Ramshot LRT 300 Win Mag

[Joshua McAda]

Anybody have any experience using LRT for 300 win mag? It's the only powder I can get my hands on, works great in 300 PRC and 338 Lapua and so I'm very curious how well it would work with 230 OTMs or 225 ELD-M in 300WM.

Given the similarities to the .300 PRC you should be able to extrapolate then starting low work up slowly watching for signs of pressure.

There is some good information here along with some photographs:

I use it in a 300 ultra, shooting 210 vld's and it works great.

Gonna be pretty slow for 300 with all but the ultra heavies. Even then don’t know if you ll get it up to pressure. One way to know!!

Burn chart puts it right there with Retumbo. I'll do some load development. if it groups well at 1000 I'll let y'all know.
