Give three rounds of Retumbo and RL-25 each a try if you can find someone willing to part with a few grains. Find your best H1000 load and add 1 to 1.5gr for both Retumbo and RL-25. You never know. I've tried this on most of my guns and with two they shot significantly better using RL. Not an issue for me using temperature regression. Shoot the RL on a cool morning if you try some. H1000 is a great powder but with only 6 rounds to add to the mix it may be worth the effort.

If you're finished developing the 210's, try three rounds with Retumbo. Same for the 215's when you get them.

Riley......77-79 grains of H1000 shoots one ragged hole with the 215's in my rifle. Use std br2 or 210 primers. I shot 80 grains a couple of days ago at 3062' but group opened up a little. It will max out at 81 around 3100'.
Retumbo also works well with a little more velocity. I would start the retumbo at 79 grains and you will likely max out around 82-83. You should be able to easily crack 3000' even with your 26" barrel. The 215's have a short bearing surface which will enable you to reach the velocity you can get with a 210......Rich
p.s. I'm trying to send a pic but my computer will not upload the file right now?

Thanks Rich, how far off the lands are you? I have 195 of the 215s headed my way. I have lots of H1000 that i want to use, i am not looking for top velocity but top accuracy.
