Thanks...to clarify the cooling issue was that by the time I got the "tower" constructed to get the target viewable from my shooting bench I had 15 minutes left to shoot AND retrieve the target/tower. So I had to fire off all 4 shots as fast as I could load and shoot accurately then run out to retrieve everything.
To be fair, besides the cooling, all four shots FELT solid. I do not think rushing hurt my shooting just the cooling issue, I can't wait to repeat this in a more conventient/cool setting (not 90+ degrees, my gun hates heat).
I had the same thought as you, the majority looked to be windage. However since it was virtually dead calm and I know from previous summer shooting that my POI shifts once the barrel gets too hot, I think the two shots to the left were the last two after it got hot though I'll never know for sure.
The heavy conicals have done well at long distances in MLs for over 150 years, it doesn't surprise me they work for you. Try some of the newer, higher BC sabots like the FTX or 300gr Shockwave. Personally I think the 325 FTX is the best comprimise between weight and BC out there right now that will stabilize out of a 1-28" twist. I would love to build a Rem700 or Savage conversion to shoot this bullet sabotless in a .458 barrel but that is priority #2 on my gun wish list. This would enable smokeless shooting (my state allows smokeless but gun caliber must be .45 or bigger) so I could improve trajectory by increasing velocity -- but I'm not sure I'd like the recoil generated.
