[QUOTE="Dano1, post: 946093, member: 14209"] When I first tried loading for this rifle, I was dead set on loading Bergers for it First the 140s then the 130s, It wouldn't shoot either, however, while trying both bullets, I learned that US-869 and Retumbo were too slow and Retumbo yielded decent groups. H1000 wouldn't group under an inch nor would IMR7828. I would have stayed with Retumbo, but couldn't get it to group under .800". I then tried RL-22 and groups were .750" a little improvement with the best velocity at 3100FPS. I banged my head against the wall and decided to switch gears again and tried the 129g Hornady SSTs and to save some time, I decided to use RL-22 Right off. "Pow", Groups magically went to .300" instantly. At this point I decided to try to improve velocity, and started playing with charge weight and primers. With top end loads, I found that during cold weather (20 degrees and lower), the velocity with RL-22 was about 100fps slower, at 95 degrees pressure spiked and I started blowing primers. To resolve this I switched from a Large rifle primer (CCI200) to a Large rifle Magnum primer (CCI250) for a better ignition at low temps. And reduced top end loads by 1 grain to prevent blowing primers. Final velocity is at 3125fps. As a Side note, Federal Magnum Match primers yielded a very low ES and accuracy was better, but these primers are extremely hard to find so I decided the CCI250 was the better way to go. All the powders you have indicated will work good, it just depends on what your rifle likes. I didn't have the opportunity to try Magpro or VV N-560, I can't get them here. But the RL-22 is working quite well, it is a dirty powder and is a pain to clean, but the accuracy it yields in this rifle is worth it. I'm hesitant to work any other loads as all I would be doing is wearing out the barrel, The cool thing is that both 129g SST and Interbond have identical BCs and they fly the same, we shoot the SSTs for Muleys and Interbonds for Elk. Hope this is helpful, Dano [/QUOTE]
