Most of my loads for my deer hunting rifles I use IMR 4831 powder. For bullets this year I'm going switch to Barnes 180 gr. triple shock bullets. In my Barnes reloading book they had the best luck with H4831SC. I want to experiment with something different, has anybody out there had any good luck with any particular powder?

I've had good luck with H1000, every load I tried got me .5-1" at 100 yards in my old Vanguard Sporter. Below is one of my typical groups using H1000 powder. The bullets I used were Hornady 178 grain A-max's.

I get sub-MOA with 82 gr of IMR-7828, Rem brass, 180 gr Partition or Hornady, Fed GM mag primer. You might be abe to go up to 85.0 gr in Weatherby brass.

86 if your rifle allows and you believe the IMR Handloader's Guide for Smokeless Powders.

I use surplus WC-860 powder (similar to AA8700 or H-870). Fed 215 primer and a Hornady 190gr or Sierra 200gr. Shoots about .75 MOA.

I've been shooting the 300 for about 25 years. When I first started, I used MRP and H-4831 using data from the old Weatherby Guide. It even gave you a "factory equivalent load" (81.5 MRP). When RL-22 came around, it practically identical to MRP so I use them interchangeably. IMR 7828 will yield a bit more velocity, but I get factory specs 3250 or so with MRP or 22 and 180gr bullets. jorge
A good principle to guide me through life: “This is all I have come to expect, standard lackluster performance. Trust nothing, believe no one and realize it will only get worse…”
