Remember-check multiple sources and work up loads in your rifle(s)
Well, nothing to brag about but I have it worked out to have a load that works in two guns and also “matches” Black Hills 175 match which I have a lot of dope on.
No pics of the first set that I did last week. Lee and Hodgdon list 42 start and 45 max for this combination. I called Sierra and they list 36.? to 41.7 max. I loaded 42.5 -44.5 in .5 gr increments accuracy load was 44.5 but the primers were flattened. I went back and loaded 41-43 in .5 grain increments and ended with 43 as chosen. No idea what happened on that charge with 43 on the Remmy, velocity was low on one shot and I obviously pulled that high one:mad:
03-31-11, was 45 cloudy with a mist DA -237. Used a pack w/saddle for the front and rear bag, was prone. No work done on the guns in regards to triggers, etc. all stock.(700 has Hooper Ordnance DBM-uses AI mags)
Remington 700 SPS 20" with Leupold M3
AI AE II with NF 3.5-15 x50 mil/mil, w/zero stop.
Once fired Black Hills brass, WLR primer, 2.8 coal, Varget and 175 SMK.
Nothing fast but they’re safe!
700, average velocity was 2439–that’s with 43 grains of Varget and the BH loads I chrono’ed
When I did the 44.5, I was 2525
AI was 2470 with 43 of Varget and BH was 2478. The 44.5 was 2625, but when it gets to 95+ around here that would be too warm with that round-be safe
When I checked that BH’s last it was 70 degrees and it was 2500, not fast, but accurate–gets me to 1K though.
What you see is the 700 on the left and AI on the right. The two upper rights were two controls with BH for checking the chrono and also checking CCB since I will keep collecting that data.
For the hell of it, I shot one each of the loads on the bottom left with the AI to see what difference there was with all together(no 43 there as I used it on the 700.
Anyhow, though I would share a recipe. If I was only ever shooting at 100, I would use 41 grains as it was accurate as well-I could throw a rock faster though–
