Hey guys~thanks to everyone who chimed-in on the last thread (H322) and I now have loads worked-up using it and some RL-10x. Today, I had a chance to pick-up some H4895 so I did. Wondering if you guys have any data you'd like to share, to get me started. My Googling seemed to turn-up a few ideas using it and bullets in the 39-40gr. range, but I'm flexible. I have a few 39gr. SBKs left (with nothing available when they're gone), but some 35gr. Berger HPs, 32 and 40gr. V-max.
Not sure if I posted this photo here or not, but here is the new rifle on day #1 of load testing at the range. Too darn cold, but even the southern-most part of Canada (where I live) doesn't want to let go of winter this year.

Cold up there still, eh? One of the reasons I don't live up there any more (that, and the stupid gun laws!).....here the rats are up and begging to be shot already.

Hang in there, spring will spring up there eventually.......... "they" promise.
Can't give you any magic 40gr formula using H4895, but I can show you a typical group shot with my M700 204 11-twist using the 40gr V-Max during load development. I don't shoot much paper, mostly critters, so this is from my files just to show that the 40gr VM does indeed shoot. My Cooper 12-twist also tolerates the 40's.
Play with charge weight and seating depth, and you'll most likely find that 'sweet spot' for that nice 'lil Cooper.

Hey Rick~thanks for chiming in. Yeah, nasty here today...about -4C and 30km/h winds. If you're from up here..I don't need to do any conversion for you!
Guess I'll dust-off the 40grs again and try them out. Pretty ugly groups using them with H322, and I haven't bothered to look if there is any promise trying them with the RL-10x. As for punching paper~really not my thing, I just do it for load testing. I prefer my targets to have fur. Groundhog fur to be exact.

Wish we had prairie dogs/gophers here like you guys have out there. Trying to set-up a hunt in Alberta for gophers, but their numbers were WAY down last spring/summer, so my hunt was postponed. Correction, they prefer you don't call gopher shooting "hunting" in Alberta. lol
