Well Im not sure if anyone here gives a rats ass about BOSS (http://www.browning.com/faq/detail.asp?ID=107), but I have been curious as to how much it will improve the groups, on say... well anything. So here I sit with my .300 and its big BOSS brake which works pretty good as a brake, but will be worth a damn as a BOSS?

My base load is a 165 Sierra GameKing sitting on top of 76 grains of Reloader 22 powder, with Winchester brass and CCI 250 Magnum primers. It should give me ~3100 FPS, I could run it up to 78 grains and 3200 FPS, but I'm under the illusion that if I back off a few grains with my "mild" loads, my barrel might give a damn. Probably not... but It helps me sleep at night.
The purpose of this load is for my all around animal killing, target maiming, zombie needs, as the bullet is cheap (Paps gave me the box, he didn't want to feed them to his .30-06) and it Sierra totes it as a capable of taking up to elk. It does wonders on praire dogs (doubt its expanding, but they didn't feel any difference) and should handle coyotes and deer fine.

Right now, with Mr. BOSS set at a factory suggested number for 168 grain loads, I can hold about an inch at 100 yards. This would be outstanding for a Fudd Gun, but my .300 is a fucking shitty hunting rifle, (probably a poor target rifle too) so Im after tighter groups than 1". I could do extensive case prep, but that tends to defeat my ideas of a GP load that I can reload several hundred of, quickly, and employ for any and all sorts of shooting. Any accuracy gains I see in the next months, should be due entirely to my adjustment of the BOSS brake.
I'll update it as I go, hopefully with some decent gains. Right now, its a bastard outside (somewhat hot) and after shooting 3-6 rounds the barrel is scorching and doesn't cool for some time.
