[QUOTE="Idaho Trecker, post: 2996707, member: 67706"] Thanks for your concern. I stopped when I saw/felt pressure signs like I do with any other cartridge. I guess I will start preface any data I collect with MY rifle more often. It's sad that it has to be said constantly but as you said it's the internet. Yes it is above book listing but as stated they are very conservative and run at Sammi length. Also, their 250 grain bullets have VERY long bearing surfaces that will slow them down and see pressure sooner. The nosler loads are all based on the super short Sammi spec with their long bearing surfaced bullets taking up a lot of case volume and building pressure sooner. No I do not have a strain gauge. Do you have one? Recommendations on one? I had this throated long. My dummy round was set with the boattail 050" above the neck/shoulder junction of the case. The 250 smk has a very short bearing surface. In my testing I've done I've seen between 60-90 fps more (same charge) just with having a bullets seated .100" or deeper vs 020" off the lands. This is a brux and in my experience they seem to run a little faster than most others. All the little additions from the reamer to the barrel to seating depth and bearing surface length add up to where I'd expect it to be. [/QUOTE]
