Re: 338 Lapua load development with 300 grain Sierra

Those groups were shot at 200yds so the bullet tip didn't cause that much variation. It may or may not cause some but it would probably be measured in thousnads of an inch and not 1/2"+ increments as you are seeing at 200yds. We're seeing differences measured in 2-3" of vertical at 1000yds to give you an idea.
I would say you are experiencing load developement issues (assuming you felt comfortable with your shooting behind the rifle [img]images/icons/wink.gif[/img] ) I see your going is .2gr increments which is good based on my experience with this Lapua case. 1/2gr increments is too course from what I can tell for whatever reason. It doesn't make sense, but that is what shows on paper for me and some other 338 shooters also.
Could be that H1000 isn't the powder for your combo. What primer are you using? I beleive you mentioned that conditions weren't the best...... don't underestimate the conditions in which you shot them!!!

But to directly answer your second question, David's bullet tip tool is around $30 I think.

Snow and rain were continously pouring as I was shooting my groups. I am using fed 215M primers, I tried a bunch of loads with the 210M primers and pressures were much higher and accuracy wasn't as good, the 210 were running a bit faster too.

Steve, I will shoot some h1000 at 1000 yards and see how it does at longer ranges. Then if I'm not happy with the performance I'll try some RL 25, and maybe some Retumbo. I like to stick with Hodgdon powders to keep the temperature sensitivity to a minimum. Plus I have 16 LBs. of H1000. What things would you reccommend I try to get the H1000 shooting better?
