[QUOTE="Bang4theBuck, post: 1858060, member: 73596"] I would strongly encourage you to do your load development with a chronograph. I would put a shout out to those on the forum to see if you could meet up a fellow shooter and borrow a chronograph, if need be. If you cant do that, then I would work in developing the load at ranges that that would show you the velocity deviation via impact elevation. 300 yards maybe. Unfortunately, I am speaking g from experience when I say that I've found many ¹/4-3/8 moa loads at 100 yards only to find out later that the es was 30-40 fps, which makes long range predictability really tough. As for you components, I think that the Lapua brass will give you better accuracy results, typically, but the hornady brass can be decent in this cartridge and will likely have significantly more capacity for powder. So, as crazy as it sounds, using that brass for a rifle with a shorter barrel like yours may not be a bad idea. (I hope I dont get beat up for that comment). Of the powers you listed that you have, I would probably go with the Varget, since it is an extreme powder, and wont give you fits with temp changes, but I think any of them could work. I dont have any experience with H380. I dont know if any of that was helpful, but I hope so. [/QUOTE]
