[QUOTE="keithcandler, post: 1765218, member: 3728"] #4 minimum, #5 preferred. Great post JE! I found a pawn shop speical, a Savage Pump in 30/30 and these rifles are famous for being accurate. I work up loads at the rifle range and came up with a 1.75" load fairly quicky with a 4x12 leupold. I put on a doughnut, immediately the groups went down to just over an inch. Shooting two shot groups, I tuned the doughnut to where I could shoot 5/8"-3/4" at 100 yards, five shot groups. Groups at 200 were great, also. You have to wonder if people will think you are Queer Bait using one of those rings on your barrel, however! Different is sometimes awkward. Next attempt was a very accurate Rem SPS sporter in 223 that shot 1/2", got that barrel down to shooting in the high 2's. Next was a Ruger 270 in the boat paddle stock, not bedded or free floated, got this rifle down to 5/8" shooting 110g ttsx with H4350 at near 3400fps. I have to say that it is a real ego stomper to use one of these darn doughnuts, but dam to they work...easy also! It had been a while since I went through the BOSS Phase on all those brownings A Bolts and BAR's. So, I decided to try a RAS tuner/Brake on my 6 XC. Photo bucket has locked me out or I would show you targets of the tuning, three targets went from group size to .070 to .191. Next, I bought a Harrells Tuner Brake to put on my 6 DASHER, dialed that barrel in to shoot in the 1's real easy. I have a Mike Ezel that I am about to put on a 6 BRA, it is a tuner with no brake. I work up my best load with the tuner screwed to the rear. Then start working the tuner out in two increments at a time. Groups will get to a point to where they open up, then close back down. This very tight group we will call a node. There maybe 5 nodes in a single revolution of the brake around the circumference of the barrel. For guys shooting factory ammo only, the Harrells tuner/brake would be a no brainer to install to have incredible accuracy as many thousands of us knew with the Brownign BOSS system. I am sure that Harrells can make you a tuner without the muzzle break if that is something that you do not like. [/QUOTE]
