105 A Max and the 243?

Who is getting 2950 to 3000 fps out of their 24" barrel and what powder are you using? Thanks.

I'm getting 2775 fps with 47.0 gr of Retumbo out of a 22" barrel. I chose a lower velocity node, but I think with a 24" tube and choosing a node closer to max, would get you around 2950. In the Hodgeson manual, they say the max charge of 49.0 gr of Retumbo was running at 2986 fps out of a 24" barrel. Good luck.

I'm using 38.0 H4350 out of a 22"barrel. Others have chronoed loads with that charge and got around 2800. Not all rifles are the same and my barrel is shorter so I should be getting a little less. Seems alot of guys are running H4350 and getting good velocity from it. I picked a lower charge in hopes of taking it easy on the barrel.

Retumbo baby! It got me 3k from a 28" Lothar Walter.

Around 48.5 grains, with a magnum primer. This is a compressed load. Be prepared to pour that powder slowly.

I've gotten there with Supreme 780 and Hybrid 100v.

115 dtac at 3120 in a 26" bartlein with 46.5 gr of RL25. I also got 2900 out of a 22" shilen with a dtac and 39 gr of RL17.
