I am only shooting about 1 3/4" groups at best at 100 yrds. I've had the gun shecked by Remmington and they say it is within specifications. I have the model 700 SPS. I've tried custom loads and we are still working on them. Other than trying different loads is there anything else I can do to help with accuracy? Does anyone have a load they would share with me for this exact gun they like and that is accurate? Like out to 400-500 yards? I would like to be shooting 6" groups at this range. I have shot rifle for years and I have a Remington 700 SPS in the 30-06 and I can shoot 3/4" groups with a factory load at 100 yards. So, I am very comfortable with the Rem. model 700 and very cofident with my 30-06. The 300 R.U.M. is new and I went through a break-in barrel process (which was then trumped by a lapping process by the company). The gun used to shoot 2 1/2" groups at 100 yards (at best) and then the guys at Remington did do a little work, they recrowned the barral, lapped it and one other thing with the end of the barrel. They shot 1 1/2" in groups (I'm guessing in a lead sled). Since the work done I have shot three groups of five shells. The worst group was 2 1/2" and the best was 2 1/8" (I kept my paper and just measured it). I had no wild shots...they could have all been coverd by a small circle. The factory loads (before the work was done) were Remington Premier Core-Lokt Ultra bonded 180 gr. bullets, power level III. I also tried the scirocco bullets (Same info. as above). My trigger has also been adjusted to 2.75 lbs. The loads I shot after the work were hand loads. Rem. casing, Hodgeden powder (92.5 grains seemed to be the best) 208 grain Hornady A-Max bullets (not the best for hunting but great coefficient for accuracy). and Winchester mag. primers. I use a concrete bench with a small adjustable Caldwell rest for the front of the gun and a sandbag in back. I let the barrel cool between shots and I do my best to squeez the trigger and let the shot suprise me. I have a Leoupold Gold Ring 4.5 X 14 power scope on. I know my groups are not as tight and that could be due to not having a lead sled but even with the factory 1.5" group I'm looking for tighter. My next step is to have the barrel floated and look at bringing the bullet out further in the casing but I should be tighter at this point in time. Can anyone help?
