Re: Remington 700 Police 338 Lapua rifles
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: Badshot308</div><div class="ubbcode-body">I believe from his earlier posts he was running 88 grs of Retumbo and 86 grs of RL25. I called Sierra recently to see if they had done load development for RL25 in the 338 Lapua with the 300 SMK. They still have not, and the tech referred me to data in Lymans 49th edition reloading handbook. For RL25, Lyman's starting load was 81.5 with a max load of 87.0 at a pressure of 61,800 psi. For Retumbo the starting load was 83.0 with a max of 88.0 at a pressure of 61,700 psi. Lyman used a universal receiver with a 24" 1-10" twist barrel. Going to Hodgdons online reloading data page, they show for Retumbo and a 300 gr SIE HPBT, a starting load of 85.0 gr and a max load of 94.0C at a pressure of 53,400 CUP. Different units of pressure, but quite a bit of difference in maximum load charges. </div></div>
I stopped at 89 grains of retumbo. No signs of over pressure at that point, but it was about 35 degrees outside and I was already at about 2620 fps.
Without shooting more, I'm thinking I may have a blueprinting issue with my rifle. I had a guy suggest going with neck sizing instead of full length to see if that cures my accuracy issues. Anyway, this thing is so inaccurate, I'm having trouble buying anything but a blueprinting issue.
In my other rifles, I'd never see this bad of accuracy even with the very early stages of load development.
Also, I didn't mention it before, and it has nothing to do with accuracy, but the damn thing won't eject brass consistently. By consistently I mean almost never.
I'm thinking the guy who built my rifle was probably drunk or stoned, or maybe both.
