Has anyone had a chance to try this yet? It seems to be a high energy, high density powder that may have some good possibilities for the Sherman and other cases. I wonder how the temp stability is?....rich
The 66 grains of LRT in a 6.5/284 behind a 140 was driving me crazy as it was supposed to be the same burning rate as Retumbo so I called Ramshot and had a nice chat with their tech. He confirmed that 66 grains was indeed the max load, but couldn't/wouldn't explain the approx 10 grains difference in charge needed (if you could put that much retumbo in a 284 case) which of course you couldn't!
When you look at data for the 300 RUM, the charge weights ARE similar. I know different cartridges act differently with the same powder, but that is REALLY extreme.
At any rate, he did say that LRT would give 110' more than a max load of Rimshot Magnum, which is saying something! He also said that they tested the powder for temp sensitivity from -40 to +140 and saw 3-5% variation. I'm not exactly sure if that is a linear scale, but would like to know if it was the same ratio from 20-90 degrees F.
Yes, I talked to a tech also and was confused. He said it would be to slow for 7WSM and 7WBY. but then they use it in 6.5-284 and 30 Nosler. Doesn't make sense to me.I called their tech a while back as well and got the same answer. I left as confused as I began with the same question. Ya, it would be great if you could get that much in?? It's kind of like the old saying " if we had a little ham, we'd have ham and eggs, if we had any eggs"!

Yes, considerably slowerSo it is slower in burn rate than Ramshot Magnum? Would that be your take on it Rich? Or not necessarily so...
Slower than Ramshot is a must for my use.
I should post a pic of my powder stash sometime!Nice. Here I go again. Another pound of powder added to my reloading warehouse.
