My 1322 has the stock 10 inch barrel, btw
On anything beyond 15yrds I definitely prefer the 1377. Beyond that distance with a 1322, you simply can see the pellet trajectory. Which is a kind of loopy one, actually.To me the 1322 is a short distance up to 10yrds puncher only. And does that great !
I would expect that with the same vavle the .177 + heavy pellet has to have a range advantage. In powderburners whenever they neck down a cartridge meaning the amount of gunpowder is the same but the caliber is lower the potential effective range seems to increase. Theres a reason why most rifle bullets are skinny/long.
that is once you make the fpe internally... which to match the fpe of the .22 with the same valve will need ~1/3 longer barrel...

point is it will end up liking what it likes at what speed it likes them at... once valve size exceeds about 1/3 barrel volume...the fpe/fps gains slow their rate increase a lot... but Short barrels and small valves tend to favor light pellets...Big valves and long barrels favor Heavy for caliber pellets...
All good information, what barrel on the 1322?
I guess it all comes down to the old saying; it's WHERE you hit em, not WHAT you hit em with.

I don't remember all the specs but something like, steel breech, 16-18" barrel, stock, scope but totally stock as far as power goes - though I'm sure got a little extra from the barrel. He never pumped it past 10 but usually used 7-8 pumps, and was was effective with squirrels with it.
Good info, If I hunted a 1377 I'd be using 10 pumps or more, so he pushed this little gun to the minimum limit and still had success (I hope they didn't suffer). I assume that was a 10yrd shot or less at that pump level on a squirrel. I bet he was using a 7-8gr pellet too? If I hunted with less pumps (which I would not), I would also use a lighter pellet. My 1377 does fine on mice at 5 pumps with a wadcutter.

My 1377 does fine on mice at 5 pumps with a wadcutter.Also the FPE muzzle energy figures of the 177 vs 22 can be misleading because a 177 needs less fpe for killshot due to less frontal area so a 177 at 10 FPE will penetrate much deeper than a 22 at 10 fpe. I going to be testing my 766 (the vintage version of 2100) on soft pine wood with a special pellet when I get it. And compare it to some other crosman/benjamin pumpers on pine. Feel free to try a similar test in your 13xx. Penetration in killzone is what matters in the end for hunting.
