Is pressure related to throat erosion? - 09/16/13
This is another "just curious" question.
Let's say I'm shooting a 7 Rem Mag. I have a high pressure load and a low pressure load, using the same grains of (different)powder. If I'm shooting a lower pressure load, but with the same grains of powder at the same speed, would throat erosion be less? I'm guessing it would.
I've heard that slower powders are more damaging. So if I shoot a reduced load with a really fast powder several hundred feet slower(Blue Dot)in a 7 Mag, throat erosion is no longer a concern, right?
Last year I sold my two 7 Mags. I bought a 7-08 instead. I was struggling to get my ES down where I wanted it with the magnum. And I thought since I mainly do target shooting, there was no sense it the extra recoil and shorter barrel life.
I'm really liking the 7-08, I was just wondering if 47 grains of H4350, at high pressure in the 7-08, saves more barrel life than 59 grains in the 7 Mag at lower pressure.
Thanks
