I'm strongly considering order four tins of CPHP's since they seem to group well out of these guns.10 meters. Try the domes too, they gave me even smaller groups.

stroke is 6-1/2"
you guys are killing me i am waiting for two 362s worse then a kid before Christmas.
Loks like I will be getting a second one as well (sigh ) and will try the .25 if the report comes back that it will work. You all are a bad influence!

You all are a bad influence! I've been thinking that a .25 swap would be nice for that wadcutter mold you just sold me Before I place my order for an Alchemy brass breech, is there any reason I should not? I'm also considering the Alchemy aluminum breech, but I like the ambi setup on the brass breech. my wife is a left handed shooter and I find that I like a left handed bolt even when shooting right handed with light weight rifles. I want to stay with irons for this rifle, and going to the Crosman steel breech forces me into not using the factory rear tombstone, which I quite like after getting used to it. Since I'll have the TP out anyway I'm also ordering a Magnum Airpower upgraded port and bushing. Also I'm not going to lie, the bling factor on the brass breech is undeniable. With a beefy anodized black aluminum charging handle and a brass trigger it should look amazing.

With a beefy anodized black aluminum charging handle and a brass trigger it should look amazing.I was JUST thinking that as well... After my experience this evening with all sorts of scope and barrel movement, I'm glad I went with the long steel breech and will be drilling/tapping another grub screw as well. I passed on the brass and aluminum for that reason, I want serious rigidity.
I took the trigger group off today preparing for some trigger work. I noticed that the same method used in the 13xx platform was used in the 362. A notch in the pump tube for the valve to seat against. Anyone planning to pin the valve? With the longer stroke and more air being forced in per stroke, I wonder if the same rear valve deformation and potential for the trigger/valve screw breaking from the valve being pushed against that notch can occur? One of the Crosman engineers said they put 80,000 pumps in a test rifle. I would be interested in hearing from them how the valve held up after all those pumps?
I'm thinking that maybe the stock 2240 probe along with the steel breech might not be seating pellets far enough I need to chamber a pellet then take the gun apart and have a look because the C362 probe has a longer nose on it compared to the 2240 probe.
I just ordered an extended probe from Alchemy Werks, no wonder it's so much floppier with the steel breech than it was with the plastic stock breech.
