OK, playing with my rum again trying to find the perfect load. A little history, new broughton barrel two years ago 27 3/8, 1-9.3, #4 contour ,blueprinted action, sako extractor, , Muzzle Brake, Bell and carlson full aluminum bedded stock, canjar trigger, Sightron S III 8-32x56 worked up a quick load that worked and hunted with it. Load was 97 grains of RL 25 with a velocity of 3300 using federal cases with federal primers and 225 accubonds. Well, this was a great load until I started to reload some of the cases. Every other one had a loose primer pocket after only one firing. Well, with the cost of brass and the availability problem of brass, I decided to work up a different load. Went to the range a couple of weeks ago and loaded up some rounds with 100 grains of H 1000 and very suprised that I was getting over 3300 and some pressure signs. In the past with H-1000, I would be lucky to get 3100, so powder has gotten hotter. So, I loaded up some rounds with 99 grains of H 1000 and shot them over the new chono today. 225 barnes tipped tripple shocks shot about 3/4 inch @ 3300 and 225 accubonds shot about 5/8 @ 3250, not bad, but had a few more to try. 94 gr of RL 25 with 225 accubonds shot about 3/4 @ 3130, 95 gr of RL 25 had 3 shots in 3/8 with a flyer on 4th shot of about an inch @ 3200 and very low deviation. I also decided to try a load that another member was having good luck with, so I loaded a few with 86 grains of IMR 4350 with 225 accubonds and had 3 cutting same hole and 4th 3/8 off and hoovering around 3200. Very promising, but some ejector marks on the cases. Then I tried the same powder charge with some tipped tripple shocks and some definate pressure on the first shot and blew out a primer on the second shot around 3250, but definately high on the pressure. To keep all of this in context, I shot 3 federal factory rounds loaded with 225 accubonds, very low standard deviation, but lousy accuracy around 3 inches. I got home and pulled a bullet on the factory round and found 91 grains of some kind of powder, maybe h4831 sc, but not sure, doesn't match anything I have. I am temped to pull a few more of these factory rounds, neck size and reseat the bullets to magazine length the same as the rest of my reloads. Just throwing this info out there, the gun shoots well, probably a lot better than I do. I am leaning to the H 1000 load to get away from the temp sensitivity of the rl 25, since most of my hunting is when it is cold out. I have also done some testing with 225 hornady interbonds and the three of these bullets seem to be flying about the same @ 700 yards. It was a little too windy today to try and shoot any distance for load development, maybe tomorrow. Any comments?
