I have a 760 whose serial number indicates it was made in 1997, and from memory, thats roughly when i purchased it (yes, it has a rifled barrel). It generates much more power than a stock 1377 that i purchased a few months ago. From what i understand, the 760 prob has a brass valve and the 1377 an aluminum valve, would i get the power that the 760 currently produces in the 1377 if i swapped valves?

The 1377 has a stock, a crosman steel breech, and a centerpoint scope, also did the trigger work and recrowned the barrel-just wanted to explain that ive got a little bit of time and money invested in the 1377 and would like to increase the power a bit without grinding parts away from the valve or spending any more money.

I know some of you folks are probably gonna wonder why i dont just leave the 760 as is since it has the rifled barrel-well i have pretty bad eyesight and really like to shoot with a scope, and i dont have a whole lot of confidence in the plastic dovetail on the 760 for mounting a large scope.

the big diff comes from barrel length.

First off, thanks for your alum v brass clarification. I've been to your website and you seem quite knowledgable concerning all things airgun. So a couple more questions for you. What are CURRENT prices from crosman for their longer barrel? Specifically the 1760. There are prices all over this forum but most of them are from a couple of years ago and dont help alot now.

My next questions for you are simply your opinion. I've spent hours reading all the past posts and even the archived ones, ive plugged numbers into the fpe calculators that are available online. It seems that the debate between .177 and .22 in the 13xx series of pistols is purely opinion. From what I can tell, the fps that you lose in the .22 equates to roughly the same fpe that you get from the higher fps in .177. What is your OPINION on the .177 v .22 debate and while I'm at it, whats your opinion on optimum barrel length in each caliber? (and yes, I understand that this is purely opinion-I'd rather take the opinion from someone who works with airguns and knows them than from a 16 year old kid that just bought his first one.)

I greatly appreciate your taking time away from your business and busy schedule and answering my questions.

.22 is for killing stuff, or knocking down reactive targets like FT or Silhouette.


.177 cal is for punching paper, or be'n mean to beer cans.

That is really it in a nut shell, but here is a bit more :


The .22 cal will always be more efficient and carry more energy to the target then the .177 given the same gun with
same power plant and barrel length, etc.
The 1377 pistol is a perfect example and really magnifies the disparity.

With a 12" barrel and full mods, I get this pistol to a guaranteed 12 FPE with less then 15 pumps
( usually get closer to 14 FPE with that many pumps ).
In .177 cal, and the exact same mods, same 12" barrel, I can't get it over 10 FPE.

Furthermore, the .22 simply punches a bigger hole in the target, animal if are talking hunting....and really you don't need more power to punch paper than it takes to get the pellet to the paper....so FPE only matters for hunting.
Not only does the larger pellet make a bigger hole, it carries it's energy much further down range and delivers it with much more authority than the little pill does, and penetrates further.


as for pistol barrel length, I prefer 12" for looks , balance, and power.


To look at it from the stand point of a powder burner's perspective, He would choose a slow moving 50 cal to take down a buffalo, not the way faster .223 , and for the same reasons pointed out above.
