[QUOTE="Hired Gun, post: 161479, member: 1290"] My Accumarks all shoot and have yet to find one that won't go sub moa. H1000, Retumbo and 50BMG are all to slow for a 26" barrel and that case. IMR7828 with Fed 215 primers. 200 grain Accubonds seated as long as will feed from the magazine reliably. The Accubrake is a fine brake but does kick up a bunch of dust if shot prone. I would expect velocity around 3200 to 3250 for this set up. To really get it to sing I have found that bedding the action and recoil lug tight will get rid of the fliers. Make sure you are not trying to use windage adjustable scope rings on it. They shift all over on this application. Double dovetails work well. I also prefer my Weatherby triggers adjusted down to around 1 pound. The action must be torqued down with a torque wrench. Hand tight won't cut it. Unbedded they need 65 inch pounds. Bedded I am getting away with 55 inch pounds. Make sure you are not resting the front of the rifle where the sling stud is getting into the rest on recoil. A firm but steady hold really helps the groups. I have found it is very sensitive to hold and rest consistancy. I have grabbed up more Weatherby's from people that can't get them to shoot only to run a sub moa group for them right there when they were shooting 3" groups and bad mouthing the brand. 3 shot groups are plenty for evaluation. I never shoot foulers as my cold clean first shots always go right in the groups. I use Wipe Out to clean my barrels and do it every time I take it out. My Accumarks all seem to work best with clean barrels. [/QUOTE]
