Crosman 1377 Pistol - 8.2 gr pellets vs 10.5 gr pellets

[bltefft]

As an excuse to shot my new 1377 air pistol I decided to compare the FPE of two kinds of pellets.

The two kinds wereL

.177 RWS Meisterkugeln, 8.2 gr AND .177 Crosman Premier Ultra Magnum, 10.5 gr.

I hope my chart ie understandable as presented. It looks like the 10.5 gr pellets will always produce more FPE in my 1377 than the faster flying 8.2 gr pellets.

Before I get cautioned that Crosman1377s shouldn't be pumped more the 10 times - I know. But I was curious, so I went up to 15 pumps this time.. After I did my test up to 15 pumps, I went back and pumped the 1377 5 times to see how it would compare to the first time around, The first time I pumped it 5 times, I get 444 fps, and the second time I pumped it 5 times, I got 443 fps.

My chrony is a Caldwell Precision Chronograph.

Here's my data tables: The 8.2's were shot today (4/19/21), the 10.5's were shot yesterday.

Where's the target I shot at. It was 11 yards away. I wasn't aiming "hard", just wanted something to shoot at as I chronied the pellets.

I'm happy with the grouping, but if the grouping was from my Daystate or FX, I wouldn't be. I was shooting off-hand, with iron sights (but not the peep sight).

Does anyone know what kind of accuracy I should see with this pistol if I tried hard? The blue stick-on target is 8 inches across.

So, I have the 1322 tricked out with a red dot sight and the stock that transforms it into a carbine. It is accurate as all you-know-what! Like, rifle-accurate. I also have the 1377 in pistol form with just the stock stuff and it seems to be just as accurate (shooting with the crappy iron sights on that, so harder to judge it’s true accuracy than the other with the red dot and the carbine stock)(but it seems very accurate as far as I can tell).

These would actually make really good, affordable competition-capable air pistols if only they had better sights and triggers. There are some upgrades out there, but doubt they will turn the trigger into anything like a true match air pistol trigger. The front sight is theoretically adequate, but the rear sight is really, really basic. You could probably get the metal breach accessory and then clamp on a decent iron sight... Sorry, have gotten away from your question....

I have a 1377 and a 1322. Neither have anything on them but iron sights. All my other air rifles have 3-9x40 or 4-12x40 scopes on them. Sometimes I just enjoy shooting the old way.

No reason not to enjoy that. Basic shooting at it's best. Glad you enjoy the pistols.
