190g LOAD SPECS 300 WIN MAG

[donwells]

In the spring of 94 I bought a 700 Sendaro, I was with the Sniper School and AMU the guys at the unit set the throat and headspace for me at the same specs as the long range comp rifles. I had saved up my TDY money and Premier reticle built me a Mark IV with a custom reticle designed for the 190g Match King.The specs were 1-10 twist 24' barrel 2900 FPS I was shooting the AMU 190g ammo with this gun and actually shot a 3 shot group at 300 KD range that went just under 1" but i have no idea what their load specs were but i know with the right medicine what this gun is capable of. It has been years since i shot this gun and want to get back into it. The powder that i have now is.. IMR. 7828 - 4198 - and 4350 I dont have a loading manual or know anyone who does.

Could anyone give me the specs for the 190g match king with Winchester super brass for each of these powders with a velocity of 2900 fps with any recommendations on which would be or is the best choice so i can try to get it tuned back up again. Thanks

74 gr of 7828 & 69 gr of IMR 4350 will get you close to 2900fps. Don't have any data on the 4198.

Look at the Hodgdon website for load data. https://www.hodgdon.com/basic-manual-inquiry.html
This will give you a start and published max. Obviously you have to find the right load for your gun.

I think the 7828 will give better case fill but it can be sensitive to temp. The 4350 will be better with lighter bullets (I used the H4350 for a Barnes 175LRX and 168TTSX).
