[QUOTE="Wachsmann, post: 914026, member: 10429"] Well I tried the test today and as much as I hate to say it I only had so so results. I was doing this at 400yrds and I thought the markers I used would produce something but that's were I went wrong. I used my wife's washable markers that she uses during her tutoring classes. I was only able to keep track of the first 3 sets. But it was not a bad day since I got some good volicity readings with my chrono. When I bought the 300RUM I was hoping to get about 3150 to 3200fps out of it with the 210VLD. But I just don't think it will do it with the factory barrel and not having pressure issue. Or I don't think mine will do it. I have been told that the volicities below seem to be on par with most factory guns. 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. 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. So I'll probably wait till it warms up a bit and retry this test out at double the distance and hopefully beter light conditions. Will also probably start out at 91 grains. Also I did not clean the barrel during shooting. I shot 2 fouller and then started the test.
