Throat length, does it really matter that much?

[QUOTE="Lefty7mmstw, post: 1003304, member: 48043"] Kirby, I believe I am running into the high jacket stress issues you have mentioned with the 171 barnes in my 7stw and 7rum. They both appear to love the bullet in cool/cold weather, but shoot very poorly at warmer temps with this bullet. In contrast, my 7rem shot the 171 barnes very well with a mild load no matter the temp. I am not seeing this issue with either rifle with hdy interlocks, berger target, or nos bonded. personally, I'll let my rifles have their freebore and load to mag. restrictions, as if you build the load to be accurate with the freebore the sky cannot suddenly fall in on you... If she shoots, she shoots. As to the small volume increase related to longer oal, remember that you only get roughly 25% of the case capacity increase in increased speed. So a 1-2% increase in case capacity is translated into jack squat... it's lost in the noise. [/QUOTE]
