[QUOTE="Little More Money, post: 1898553, member: 112768"] Since everyone here was so helpful I thought I'd take a minute and share the results I've had so far working up loads for this build. I have roughly 65 rounds through the barrel now, been mostly using Retumbo, Reloader 23 (per lots of recommendations here), H4831SC, and H1000. I've only loaded 143 Eld-x bullets so far. RL23 is a real dandy, I haven't started fine tuning groups yet, but it shoots really good groups at almost all powder charges, I'm getting about 2950fps with magnum primers, and about 2920fps with standard primers. H1000 and H4831SC are both super accurate, but the velocity is considerably less with both, 2700ish with H1000, 2800ish with the short cut. I still have more room to work up on more speed with both these because I haven't ran into pressure yet but I'm more focused on other powders because of the speed so far and the fact that H1000 is so hard to come by. On to the Retumbo now, which is why I came here looking for info in the first place. I'm hoping to get out this weekend and shoot some 5 shot groups and see how close the velocity numbers are and longer range accuracy. I ran into pressure with Retumbo and magnum primers at about 2800 fps, so I switched to standard primers and started working up again, this has been the first most surprising info that I've discovered so far, with standard primers and Retumbo I'm getting 2915fps and no pressure signs, 115 fps faster with standard primers over the magnums?? The second thing I've found really interesting is how much smoother shooting, considerably less jump, and way less recoil the rifle produces when shooting Retumbo vs all other 3 powders. Best groups so far are jumping the bullets .010-.020, less jump I run into pressure and less velocity, more jump and groups open up considerably. My barrel ended up finishing at 25 inches, I was hoping to get around 2950-3000 fps with the 143s but it's looking to be a little less than that. I've read lots of guys getting considerably more velocity out of this cartridge but I suspect using longer barrels? Also from what I've read a fairly tight neck and jumping bullets a short distance is not a combination for speed. Should I be happy with the speeds I'm getting in the low 2900's? Anyone else ever had a certain powder give some of the upper end velocities with considerably tamer rifle behavior like I'm experiencing with Retumbo? Again, thanks for all the help and info from all of you, much appreciated. [/QUOTE]
