300 win 180gr Sierra Matchking.

[deerslayer223]

Need some help. I've always been a nosler bullet man myself for all my loads and everyone else i've agreed to do a load for. My dads buddy asked me 2 load him some shells for his 300win I agreed he brought me some 180gr Sierra Matchking HPBT I own no sierra book and i've looked around on the net cant even find anything to get a starting load on that. Preferbly IMR4350 if thats possible if someone could give me a pick me up id love it.

I would start low with 4350 at like 67 grains and work up. Max Load I found for 180 gr bullets (only matchkings I found was 168 175 and 190's) with 4350 is like 73 grains. In my 300's I love imr4831. It doesnt matter what brand of bullet at 180 grs I shoot 72 grains of powder. Again a max load. Id start low and work up til I found the sweet spot.
