More Questions

Hello,
I know that I have posted a-lot of questions. I have another question , I'm sorry. I just enjoy learning from people who know more than me! So i am going to load my factory Vangaurd 300 weatherby to an over all length of 3.750. Today I measured the lands of my vanguard at 3.994 . That would be .244 free-bore. I know my 300 weatherby normally has free-bore of .361. I plan to load the 215 berger hybrids and I am hoping for a velocity of 2900 fps. Am I going to reach pressure signs sooner? is .244 enough to keep pressures in check? Or am I confused as to why weatherby uses free-bore.

I agree the speed with there factory ammo is insane!
But If I am reloading, and I am watching for pressure signs, am I going to reach pressure earlier with less free-bore than from factory?
With my overall length I will have .244 of free-bore compared to .361. Or am I missing something.
I understand what free-bore is compared to Jump. I just want to make sure my reloading is safe. And use the most case capacity I can

IMO this is a powder dependent question/answer. With the right powder 2900 fps should be achievable even with the bullet jammed.
