Re: GAP10 6.5CM
I have a GAP10 in 260 but my bolt gun is 6.5CM. If George gave advice on which pill to run out of it, I'd ABSOLUTELY follow his advice. I mean, he'd know.
If you're going to reload, I'd highly recommend picking up a bunch of brass whenever you find it available. Sometimes it dries up and I can't imagine anything worse than getting a new hammer from GAP and not having components to feed it.
A lot of guys buy factory ammo for it and shoot it first and then reload it. The ammo I've seen, even at funshows, is pretty reasonable in price. I personally like to have some factory ammo laying around for the first few shots.
Reloading for the 6.5CM is a piece of cake! The ammo comes with the load stuck on the side of the box. Mine said a Fed 210M with 41.5gr Hodgdon H4350 and a 140 AMAX. I mean, if I can do it, I'd call it idiot proof. I followed Rob01's advice (and others) and just use the a Hornady FL sizer. I get 0.001 - 0.002" runout with that die. It works very well and is CHEAP. Hornady did a great job with this setup.
You're gonna LOVE that rifle.
my 2 cents - consider a longer barrel. You'll get more velocity. My 22" balances VERY well. When I ordered mine, if they had a 24" I would've gone that route in a heartbeat. That rifle is just awesome.
