The previous post on the oversized bore of the P95 got me wondering about my new purchase. I just slugged my P95 barrel today and came up with 0.3565 for the groove diameter. Since I'm starting from scratch with reloading components for 9mm, I'm thinking maybe I should go with slightly larger bullets than standard.
0.358 seems to make sense for cast, though that's 1.5 thousandth's instead of the recommended 1.0 thousandths over groove diameter. Any problem with that?
For jacketed, I'm thinking about returning the .355 bullets I've got and picking up some .357. This is 0.5 thou over groove diameter. Anybody think that will be a problem? I don't think I've seen .356 jacketed bullets anywhere.
This gun is intended for plinking and working on my technique. I despise inaccurate firearms though, so anything simple like bullet size I can do to bring group sizes down is a good thing. I've got a 10MM for more serious work, which slugged out to exactly 0.4000, lucky me. Yes, that is an aftermarket barrel.
Edit: I guess there are a couple options for .356 jacketed at Midway. That HAP is a decent bullet too, from my experience. Would .356 be better/safer for my gun?
