Hey fella's,
I lent my chronograph to a buddy this past weekend and got it returned with a bullet hole right through it. Haha, he felt terrible but it's no big deal, I'll just have to send it in. Anyway, I was planning on going out tomorrow to chronograph a few more loads with my .300 and can't now. I was hoping one of you kind gentlemen would be willing to run Quickload for me so I can get an idea of my velocity with the new loads. It will also be interesting to compare the Quickload projections to the velocities I recorded a few weeks ago through the chronograph.
The specs are as followed:
.300 Win. Mag
215gr Berger Hybrid Bullet
3.675" Overall cartridge length
28" Barrel
H-1000 Powder
5 cases measured for case volume averaged 92.22grs H20 (was very surprised at the consistency of the case volumes) Filled to the top of the neck
I chronographed 10 of these cartridges a few weekends ago with 76.0grs of H-1000 and they averaged 2,885 FPS, ES=12. Really curious what my loads at 77.0grs are doing. They are shooting just as well as my 76.0 gr load and still no heavy bolt lift, flattened primers, cratered primers or ejector marks. This is as high as I will be going though, don't want to kill my brass.
Thanks in advance!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
