[QUOTE="JMac, post: 20983, member: 126"] Before there was any published data I did some testing on H-1000, RE-25 and IMR-7828. I used Speer, Nosler, Sierra Gamekings, Hornady and Swift 250 grain bullets and accuracy and velocity considered, I settled on Reloader-25. Depending on powder lot, seating depth and bullet I ended up between 91 and 94 grains. The rifle was a stock Remington 700 BDL-SS (26inch barrel) in a HS Stock and a Timney trigger. With the typical long factory throat, and the bullet set out as far as the mag would allow it was still a .090"jump to the rifling. I don't do the long range thing. Yet. I ain't good enough! I settled on the Nosler and 93 grains of RE-25. Accuracy is less than an inch at 100 and velocity is 2950fps. I have never been able to get much over 2950 without pressure signs. I did hit 3000 with one lot of H-1000 but it was a hot load and accuracy wasn't there. The gun wants to shoot, using Sierra or Hornady bullets and seated way out towards the rifling I shoot several several sub half inch three shoot groups. Smallest was .187". Anything I can answer, let me know, Joe. [/QUOTE]
