Ramshot LRT

[Fotis]

I have been thinking about trying it in my 300 Remington ultra mag with 199 grain hammers. Does anybody have a starting load or any idea what is the burning rate of this powder? I heard it's very close to retumbo but some are saying that it's closer to h869 which is super slow

All the available 300 RUM data for monos is the 180gn Barnes TSX, so looking between that and the 200-220 grain info my judgement call would be start at 88gn, but you'll have to look at the charts yourself.

I downloaded some data and it looks like 99 to 100 grains of LRT would push a 200 grainer AT 3150 or so

QuickLoad says 100.8 grains of LRT (which would be a compressed load) would send a 200-grain Nosler Accubond at 3,056 fps with a maximum chamber pressure of 64,786 psi.
