[QUOTE="Wachsmann, post: 914207, member: 10429"] When I bought the 300RUM I was hoping to get about 3150 to 3200fps out of it with the 210VLD or the 215berger or the 208 Amax. But I just don't think it will do it with the factory barrel and not having a pressure issue. Or I don't think mine will do it. I had read a lot of posters that seem to be getting 3150 to 3200fps but I have been told that the volicities below seem to be on par with most factory guns. Unless the poster were doing some embellishing. Even on the 93 grain load I did not see any ejector mark but where the primmer is hit by the firing pin I think it may be starting to creater. I seen this on another post with the cratering and the ejector mark. I don't know which sign of pressure comes first. the ejector mark or the cratering. The 91 and 91.5 is completely smooth at the edge of the dimple left by the firing pin and the 92 to 93 I can catch my finger nail on the edge. I seen a picture of this and it looks slightly the same so I think I'm at the max or very very close. I know 93 is one grain over book max for retumbo also. The good thing is all these shots fit into about a 5 inch circle. I did not hold for wind and I adjusted my turret for a velocity of 3050 fps. So this would get me on the paper in the center for what I figured and it did. So I'll probably wait till it warms up a bit and retry this test out at double the distance or 1 K and make the adjust or come ups using the velocity off my 91 grain load, and hopefully I'll have better light conditions. Also I did not clean the barrel during shooting. I started with a clean barrel. I shot 2 fouller and then started the test out in the western desert of Utah very overcast which gave that grey appearance to everything. Had about 3 to 4 inches of snow everywhere as well temp was 30 degrees.
