105 A Max and the 243?

Re: 105 A Max and the 243?

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.
