Maybe, maybe not? Can't have enough powder these days, I'v 2 #8 for 28 Nosler, 300 RUM, 6.5x284 Norma.
I'm shooting fewer and fewer overbore magnums where this powder appears to shine. Going to see how much I can stuff in a 6.5 rpm though just for fun, retumbo works great so far.

If it were me, and I do have Ramshot Magnum (no H1000), I would still use the H1000 type speed powder's, with bullets lighter than 175gr. This comes from using 7STW since it's inception.

What barrel length/twist?

LRT works great in the 300 RUM. I am shooting a 200 gr Federal TLR at 3150 with a charge of 100 grs. Tack driver!

Did some indoor data testing, for pressure & velocity only, this afternoon, with new barrel and new Peterson brass. Great extraction, case condition, pressure and velocities. Got 2-3 nodes nodes to work with and possibly another above 91gr?!

Just picked up a keg of this stuff, honest question why is it so cheap? Half price of vihta vuori and 30% less than hodgdon/imr.
I found good loads for this in my 264 win mag (26" 8 twist just over 3200FPS with 140 speer gold dot) and my 7mm-300 win (27" X-Caliber 5R 8 twist and 195 Berger at 2900 +) I started at 72 grains and worked up in both rifles.

I have been using it in my 257 Roy and have great results. Getting over 3300 in my 24" vanguard and sub 1/2" groups with 115 Nosler CTBT. Western Powders claim it's more temperature stable than Retumbo. It has worked well with no pressure issues from 25 degrees to 105 degrees. I'm bulding a RPM and my son is building a 6.5PRC and we plan on running it in both of them with 156 Bergers.

I've used it in 300 PRC with very poor results. I can get .5" groups wit H1000 but had a hard time getting anything under 2" with LRT.

We had the same issue with my son’s 6.5 PRC. I’m guessing that it has something to do with the burn rate in that shape of case. We have had great success in the 257 Roy, 6.5 x284, and the RPM with LRT.
