RAMSHOT LRT POWDER

Yep. I just use the virgin unadjusted Ba values for each powder. As you can see LRT is a pretty slow one at normal temps.
 
Ran a pressure test with LRT in my 6.5ss with 160 Matrix. Loaded from 62 to 70 grains. 62 to 65 grains ran up the target while the 66 to 70 grains shot a closter under an MOA. Primers all look good with no swipe on the brass at all. The very slight bolt lift at 69 & 70 grains. Pretty impressed. Going to work up some loads from 67 up in .5gr increments, & see how it groups.
62- 2749
63- 2807
64- 2830
65- 2879
66- 2923
67- 2996
68- 3030
69- 3100 slight bolt lift
70- 3152 slight bolt lift

I love the 338-378 Wby, just wish the brass was tougher. I would be interested in your velocity results with that combination. What is the basic rifle set up?
Just bgg e careful w that 69 to 70 gr load in hot weather......

You may also need to check your zero with it below 20 degrees.

LRT is a spherical ball powder that will be temp. sensitive.
