	A friend is having Paul make up a 32-20 barrel for his CPA. Claims 1550+ velocity with 205 gr bullet. It would seem you will really go thru cases with that pressure? Just like to hear from anyone shooting it and the positive/negative. Thanks,Pete

	Four of the good folks in our group who were shooting the CPA 32-20 all went back to the 32-40 and that move and their behalf should speak for itself. Yours Sincerely John Louis

	Received my .32-20CPA, Shilen #4, 28", 14TW, groove 0.3210, bore 0.3120 mid-September 2013. Bullet is MOS .322-205. Casts 207.5+-0.5gr 20:1. My pet load shoots 1557 f.p.s. I have used only Starline brass (cost:$ .25 per case +-). Fore warned by my friends out west., I retired 100 cases after 9X per case without a failure. Figure better safe than sorry. My brass cost at that rate = $ .03 per shot fired. Powder cost = $ .06/shot. Primers +- $ .06/ea. Can't shoot my rimfire for that. I'm 77 years old, have 500 new cases in inventory + another 500 with 1X - 6X through. I think I'm OK for a while. Still loving my .32-20CPA ............ still seeking my 1st. "250", but figure the thrill is in the chase. I am a stubborn Dutchman!

	Hey Ray that 250 is coming shortly the 32-20 CPA will indeed shoot and it sounds like you are well ahead of the game on having enough cases for you to get there. You have a couple of fellows in the Modesto and the Central Sierra Schuetzen group wishing the very best and we are behind you all the way our friend!

	John and all ............ You have been my inspiration and guided me this far. Too late to turn back now. My heartfelt thanks to all my friends who have supported my efforts. Sincerely, Ray Hoagland

	Seems to me I read Paul's reason for the 32/20 was to meet "Traditional" class rules in a short case. No rule, concerned about case life, one of the cartridges based on .357 Magnums probably a better choice. Just a guess treat it as such Boats

How can one take a "Traditional" case, stretch the twist, bullet weight, ect beyond imagination and call it "Traditional" yet if one uses a Hornet case, nearly identical to a 25-20 if it not? Sound like all BS to me

	Good way to look at it Bob. I have A 32 Ideal in one Borchardt Zischang, cases made at RMC. The other Borchardt set up for BR is a 32-357 RKS. I will still call it A 32 Ideal in Matches, if they need the "Traditional" It is as close to the 32 Ideal as you can get.

	Back to the original question ............. The details of my rifle are above. From Sept. 2013 - March 13, 2017, I have put 5,250 rounds through the barrel. SO FAR, no signs of case failure, case head separation or loose primer pockets. I am working with 950 "active" cases. I use them "in progression" - some fired 1X, 2X, 3X, etc. I have 100 that have gone 9X. I'll try for 10X, then retire them for reliability sake. I've found my best results with a bullet of 205 - 207gr. I have a beautiful MOS .322-218, but I suspect it is just plain too heavy. One more test to confirm, then back to reading wind, mirage, etc. Perhaps a heavier bullet and higher velocity contribute to case deterioration. Shooting friends with far more experience than I lead me to think this is the case. I don't seek trouble!

	"---heavier bullets and higher velocity lead to case deterioration----" Only if the higher velocity is pushed by "TOO high" pressures for the case,etc. Other factor as you know, if that heavier(read too long) bullet needs more velocity to stabilize, you need a shorter bullet. beltfed/arnie

	Arnie, It seems my "go to" bullet (Mos .322-205, OAL: 1.160") casts @ 207.5 +- 0.5gr shoots best at 1557fps. My Mos .322-218, OAL 1.150") casts @ 218 +- 0.5gr shoots LESS well using no greater powder charge & produces lower velocity. Experience tells me that, if I increase the powder charge, I get pressure signs from my fired primer. I figure I'm close enough to the edge - don't want to go over. Maybe that's why I'm having so much fun with the .32-20CPA?! Thanks for your thoughts, Ray

	A lot of case life in the short .357 based cases is up to the shooter. If you want to shoot 230-grain bullets in a .32 because Greenhill says that you can than you are going to have short case life. When I started with my 32-30 I shot a much longer bullet than I do now. I couldn’t get more than three shots out of a case before sticking forced me to go to a different case. This made for poor performance on paper. So I went to a .050” shorter bullet and backed off on the powder charge. Now I can shoot 50 shots or so before the case gets sticky. This gave me the kind of consistence it takes to shoot a clean target. Just because you can doesn’t mean you should. 40 Rod

	IMHO the 32-20 CPA is alot like a gal that has horses; the early promise of fun but ultimately heartache at the end. My third year and I'm still struggling. I think the grey-beards on this forum called it correctly. I see a rechambering to 32-40 this fall.
