Guys just built a custom 1-8 twist 243ai and have new fire formed lapua brass ready to go. Just got some RL26 in today and want to try it with both the 105 grain Berger and I picked up a couple of boxes of the 103 grain hornady eldx . Anyone else out there playing with RL26.

I have threatened to...but H1000 just works so well. I will likely get off my butt and try some in the spring.

Yes, but only with a plain vanilla 243.



They averaged 3140 fps with a 24 deviation. It's a 22" barrel.
A little slow for what you are looking for I imagine, but if I upped the powder amount the accuracy began to drop.
This is an 8T barrel. 100 grainers were abut 100 fps behind the 95, but accuracy was slightly better.

I'm going to soon...I use RL-22 now with 105 bergers.

48 grains under a 105 hpbt in formed Lapua gets 3,140

I’m at 49 with gfl brass at 3175 fps pushing 105hpbt.

Big game rifle thread has lots of information I bumped it up for you.
