The rifle I used is a model 12lrpv. Everything is stock on this rifle, I haven't even bedded the action on it. I figured why mess with it because it's always shot great. I did work on the accutrigger to lighten it up a bit. It pulls at about 1lb. I've always liked the suprise factor of the gun going off when benchrest shooting. The scope is a Sightron 36x. This gun has never shot a critter. Nothing but paper. Although there may be plans in the future that will change that
One thing that I do with all my rifles and you may too is that I use a torque wrench on the action screws. That way I know the action doesn't have any pressure points on it. The ammo I use is Nosler brass, 35gr Berger bullets and VV N135 powder. The charge is 26.9 gr. Seating depth is irrelevant here because every gun is different. I always try to start at 10 thousands off lans(hope I spelled that right)
I try to keep my brass all at one length. Most of the time I go ahead and trim b-4 reloading just to be sure they are all the same length. Oh, forgot to mention that I use rem 7-1/2 br primers. I use a RCBS Rockchucker press. All of my other equipment for reloading is RCBS also. 10/10 scales, powder dump etc etc. As for dies I use redding. Just a standard set but I do use a compitition seating die. As for my bench equipment I use a Caldwell Rock BR front rest and a standard bunny ear rear bag. I'm what you call a bag sqeezer in the benchrest world. I've tried to free recoil but it just doesn't work for me. I put a light hold on my gun, take a deep breath, let about half out and hold it. Then squeeze the trigger. Pretty basic stuff.
One thing that I do when shooting at circle targets that no one has ever mentioned is that I don't line my crosshairs up in the center of the target. Your scope consists of 4 pie shapes, I take one of the pies where it comes to the center crosshair and line it up so that the top or bottom of the circle sets on your horizontal line and the side of the circle sets on the vertical line. This way you know you are using the exact point of aim on every shot. I hope that this isn't to confusing, I sometimes confuse myself.
Anyway, that's all I've got. Sorry about the long post. Hope this helps someone out there when it comes to target shooting. 
See Ya.
