I just got this gun awhile ago and it is a great value. Crosman is really putting out quality merchandise. OK, the stats first. It is a CO2 rifle using 12 grm powerlets giving about 35 shots. It has a rifled steel barrel and is .177 caliber and has a barrel sleeve, which adds nicely to the heft and profile. It comes with iron sites and has standard dovetails. It is advertised to shoot 645 fps with 7.9 gr pellets. It is 4 lbs,14 oz and 38 1/8" long. It has a two stage trigger and safety. The stock is walnut and it has a nice butt plate with a white spacer. The plate is hard plastic so it is not much of a comfort cushion.
That pretty much sums up the facts. I put a 4x sportview rifle scope by Bushnell on the gun and used it for plinking at about 66 feet. It was very accurate. From a free stance, I would say the groups are ctc within an 1/2-3/4 inch. My friend Jorge can knock down soda cans at 40 yards! Off the bench, I am sure it is better. Even a primative scope really makes this rifle great, for the sites are the standard Crosman and crude to adjust for elevation. (A little plastic piece with steps on it.) Thank the maker for the dovetails. I have put an inexpensive 4x scope, but I plan to upgrade to make this gun even more surprising. The walnut stock is beautiful and the main feature that sets this gun apart from the rest of the Crosman line.The stock widens in the front area for a nice resting area for you supporting hand. The mechanicals I am sure are identical to the many other Crosmans that are produced in varying configurations. I like the pellet loading and how the receiver swings to the side. The trigger is a light and works well here. Trigger weight is 2 pounds! Excellent. I think this is why my friends big Jorge and Javier like to borrow this gun so much. (This is often where a well made barrel and powerplant get ruined. See the model E below) The gun is metal and wood except for the plastic trigger/guard and the loading breach. Price is under $150.
The negatives are few. The CO2 loading is kind of a pain, for you really have to crank down on the port cover to puncture the cylinder. You can also expect 15% greater velocity intially with a new cylinder. I usually dry fire the first shot of the day with all CO2 guns if the cylinder has been in overnight.
Update 2012: I tried to fire this gun after years of it sitting in the closet and it did not hold the CO2. I heard the unmistakable sound of gas escaping. One of the seals was obviously bad. I decided to throw it out. I literally had put it to be thrown out, laying under some rags for months. Then, I don't know what got into me--I think it was watching the Olympic airgun competitions--I ordered a reseal kit after taking it apart. Of course, a month later when I got the time to rebuild it I had a box of parts and tiny screws, and no idea how it all went back together! (Take pictures next time...duh) With the help of a parts diagram from Crosman, I rebuildt it, and it works. I refinished the stock and added a red dot scope. You know, I think it is the beauty of the wood stock that kept me from tossing it out. Plastic gun parts of today hinder the guns of today from being kept and repaired. This is a good gun for a kid because it is not hard to pump (C02), and the red dot is an easy scope to view through.
Mounting the scope was another matter. This gun us set up for two separate attachment points--as with a scope. It is not set up for a broad based device such as a red dot. In addition, I had to be careful that whatever I mounted would not interfere with the pellet loading lever. It is kind of a strange arrangement, and Crosman has wisely abandoned it. Nevertheless, I had to find a way so the scope did not block the port. I ended up elevating the red dot on a weaver rail so now the pellet loading lever is clear of the over hang of the scope.
The groups shot is the picture is at 30 yards. about 1-2 inches. This might get better, with a bit of practice.
Let me just say I am very dissapointed with this gun. I first read a glowing review of the 1077w in the Airgun Letter. It reported how much fun people had with it at a recent show. This was probably due to the fact that it was available and many shots could be pumped out of it due to it's semi-auto nature.
The first thing I noticed when I opened the box was the front barrel site was not even close to center and the rear iron site was way off the the side to compensate. The factory obviously knew the site was grossly off but just moved the back site to compensate. A bad move by Crosman. I would have returned the gun if I wasn't so lazy, and I know I could skip the problem with a scope.
The other negative is what I have often said separates the bb guns from the pellet guns: the trigger! This gun is semi automatic and has a 12 shot rotary magazine. It has a weight of about 3.75lbs and is about 37” long with a 20 inch barrel. The gun came with two clips which are 12 shot rotary clips like the ones used in CO2 revolvers. Loading pellets is easy by hand, but, on occasion, some lighter pellets have slipped out the back of the rotary clip and caused the gun to jam. Unjamming it is easy however. Newer Crosman/Daisy products with these rotary clips make use of magnets to hold ammo in place so that you may use either BB’s or pellets, but, because pellets are typically made of lead, the magnets have no effect on them. Steel and copper BB’s work fine with those clips, but this rifle is intended to be used with .177 pellets only. I bought a Crosman 1077 because I liked the idea of having a 12 shot rotary clip in a rifle. When this gun was released, it was one of the few of its kind, and at the time I don’t remember any other gun having such a realistic design with realistic clips holding its twelve .177 caliber pellets. The Crosman 1077 is based on the exact same technology they’ve used for their revolvers, and it is most obvious when you take into account the firing mechanism which allows you to either take your time popping one pellet after another, or to fire all of them within about 2~3 seconds. Its truly semi-automatic… at least, until it jams. To advance to the next pellet requires alot of pull and this makes the trigger much too hard for reasonable accuracy. So to shoot you pull the trigger and this advances the rotary magazine, and then fires the gun. Kind of like a double action revolver. This make the trigger pull heavy, to say the least. Yeah you can hit a can at 10 meters, but you can do that with a rock. The pellet advance come first (a lot of pull) and then the release (not so predictable). Do this ten times and your finger hurts. I have read this gets easier with time. Let's hope so. Trigger weight is off the scale. I don't even think a scope would help due to the trigger effort. If Crosman separated the loading from the firing, as with the Crosman 400, this may have worked. I am not even going to post the groups since they are so sad.
On a more positive note the walnut stock is very nice. Most of the versions I have seen have a plastic stock. I guess that's what puts the 'w' in the 1077w name. Also, the pellets load into a rotary magazine which inserts into a loading block that snaps very nicely into the bottom of the rifle. Ok, I did put on a scope, a 4x scope, on the gun and I have found the accuracy to be acceptable assuming you can hold the gun steady through the trigger pull. You can hit cans at 20 feet. Probably the target maket for this gun anyway.. Accuracy at 20 feet is about one-inch groups, but deteriorates in rapid fire as the CO2 must be given time to equalize between shots.So rapid fire fun is going to have lots of low misses. Spaced shots give you 20-30 full-power rounds before the powerlet starts to deteriorate; forty to 60 shots per powerlet are possible. As a rule I shoot four magazines and then put in a new CO2 cylinder.
I guess you have to figure for the money (under $100) it's not bad for a gun that shoots out the pellets as fast as you can pull the crummy tirgger.
Update 2002: the plastic mechanism broke. The trigger was so gastly--good riddence. Usually, in my experience, what goes after years is the seals. But with so much plastic used in these inexpensive guns, they have to be handled very carefully. I hate to toss such a nice stock. What I would really like would be a return of the Crosman 400 crossed with the 1077w!
Update 2012: I plan on replacing the action and refinishing the wood stock. I bought a 1077 with a plastic stock. The kids played with the non functioning gun, and it got banged around and rusty. These pictures are the before:
I have read that there is some variability in the trigger mech. Let's hope this one is better. It will make a good gift for Little T when he is 8. First off, let's just say Crosman let me down. The new 1077 leaked C02. And I mean alot. Gas just escaping from the mechanism. I am not even going to try to fix it. Back it goes, and I will order another. The parts/seals they must be using are just the cheapest. Anyway the stock refinish has gone well and I have found out Crosman has changed a few things. Some of the diemensions are a little different, so much so that I will have to sand down the wood stock where the magazine goes in to allow it to be removed easily. As you can see in the picture I put a Crosman red dot sight on the gun. In theory it works, but I am not impressed with the tolerances of this $10 piece of plastic, so I think I will scope it, or put on a better red dot--like the BSA on the 262 in the above review. The Crosman red dot wiggles around and seems loose. There is no way to lock it down once you have it sighted in. I can easily see this thing getting moved by a simple glance. The reviews of this red dot are not flattering. More of a toy. Eh...u get what u pay 4, I guess.
Great, the replacement 1077 does not hold the C02. It has a bad seal and is leaking. Back it goes. This project just got delayed again. Here you can see I sanded down the stock. The work begins...
Ok, after the red dot fiasco, I bought an nice UTG 4X32 TS Full Size Mil-dot Scope for airguns, pre-adjusted at 35 Yards (that means you can't adjust it). It costs about $40. It is probably too much scope for this gun, but is needed to tame the trigger. What I mean is a good site picture might help with hold of the gun during the long tigger pull. Yes, I know the scope is close to the price of the 1077 gun, but if you had to buy this gun with a wood stock, it would be over $150 at this point.
I dropped the stock and damaged it slighty (oops), plus the new action is a bit different in shape which required sanding. I had to take away some of the wood so I could get the magazine out. So I refinshed it again--darker.
Initial tests show broad groups. I attribute this to the way the pellets seal in the breach. There is aways some little gap between the rotary magazine and the barrel. If this doesn't make a perfect seal the the power will vary. Here are some pictures of the finshed product. I may not shoot well, but it looks like it could. It is fun to load in the magazines with a nice click. I can go through 22 pellets in the blink of an eye. :-)
To make this scope usable I had to shim the back of it up a bit. Now I was able to zero it at 20 yards. The grouping below is of 5 crosman premiers at 20 yards (next to the magazine I am holding up), and this is from an off hand stance. It may be better off a bench rest, but I think that is about what this gun was designed to do. I only expect 2 inch groups at 20 to 30 yards. For hitting cans, that should suffice. I have heard people say this gun was designed to look like the ruger 10/22. With the barrel sleeve, the magazine loading, and the scope it really looks good. I think I have finally achieved a nice balance of looks and utility with this setup. I hope the kids like it. (It was a lot of work for 2-inch groups.)
