TheVabene73: do you think by trimming off the cone of the original valve will increase velocity to my 1377
David Matthew Summers (Matt): I've killed squirrels and 🐦🐇🐀 with mine. Since its a straight shooter I go for head shots. I hit a 🐇 and he ran off. It took 30 minutes to track him Dow. He was done.
Myles Nicholas: So it's 10 pumps for every single shot, that put me off.
Glenn Hanson: Man. I am resealing mine for the first time ever. I can see why that o ring and cup have to be in excellent condition. It's hard to believe that that pump system can overcome the pressure exerted from that spring on the inside!
frederickwentz: I pop squirrels out of trees, and killed a few rabbets with mine. Its the loading that gets me, But at 20 feet it puts a hole into the side of a old dryer. Now I may go to a flat top.
fatbarry barry: for this to be on sale in the uk it had to be under 6ftlb im sure air comes back out the valve after 10 or so pumps, seal up the overflow if its not tamper proof, i had a rifle like this called a sharpy ace you could pump it up til the pin in the roostering arm snapped 20 pumps would be over 35ftlbs
Kaka Brar: what good is that gun for ? i mean we cannot hunt with crosman 1377. 600 fps is still little less for small game
Joshua Purple: nice detailed walk through of the pumping mechinisms of the 1322/1377...I have actually been looking for somthing like this for awhile now...I have my new alchemy airwerks power RP pumper valve coming today and wasen't sure what I needed to do to take the valve off/apart....still looks like its gona be a pain lol
Mekratrig: Nice, clear, explanation and reason for doing the mod. Thumbs up.
quicksilver40: Thanks for the vid on the flat top parts I've been looking to add.
toneknob: another plus for using a multi pump pneumatic is that you can get full power all year round, unlike CO2..
seller559: Thanks for sharing that. You made it very understandable.
makeil kalashnicov: I really know how to spot an accent, your accent sounds like you're from maybe northeastern Oklahoma?
steve l: I live in the UK and the instructions state if I exceed 10 pumps the excess pressure is vented off, how is the pressure vented and could this be over-ridden to increase the pumps to say 15 without damage
Bob Barker: Great video I have to say though I felt like it was richard kuklinski talking.
Qyuubi786: Hey Mike do you know what type of thread the piston uses, It looks like 1/4" BSP but when I try to use a 1/4" fitting they don't fit.
NotSoDumb: What isn't mentioned is that with a modified valve, one that has had the capacity increased and a lighter spring and using a high pressure piston, you can now pump the airgun many more times than the recommended 10 times. I've done a lot of the mods, including a longer probe pin and pumping my gun up to 25 times, which seems to be the sweet spot now. You'll find that you need to put more air in the valve to get the pressure up. Replacing the hammer spring and a longer bolt probe, which places the pellet further into the barrel, keeping the pellet skirt from being centered in the transfer port hole and a few other things like a better breach, you can make these pistols really sing. Some people say that the longer bolt probe actually slowed the pellet down. That might be true for some but for me, just using 12 pumps, I chrony tested a 7.9 gr. Crosman Premiere and saw a difference of an additional 20 feet per second. At 25 pumps, I'm seeing a bit over 700 fps this old 1377 American Classic with which is unbelievable with the stock barrel.
w1bmw: Great explanation! I just picked one up today and really appreciate the lesson. I've got my stock, barrel, steel breech, etc on the way, but had no idea where to start on the innards. Thanks!
Terry Watkins: I have a older model probably late seventies, only problem I have is the pin has a washer clipped on it so I can't just tap it out. Does anyone know how I should remove that, it's pretty heavy metal and it's hard to grip with pliers
Holiday: We don\t make alot, but our group do get to travel frequently. Just this year we went to Bangkok to get pictures and their holiday schedules. We are still in a growing phrase so best we can aim for is break even. I think everyone have to overcome the same type of challenge when starting something new. Don\t give up!
