I got a PM about my loads. The 243 Win in my gallery is a Sako 75 with a 1:8 twist Border Barrel. At present I have the following loads in use:
105 AMax 42.7gr N165 10 thou off the lands 2816fps
105 AMax 39.5gr N560 10 thou off the lands 2658fps
107 SMK 43.6gr N165 5 thou into the lands not chronographed yet.
87gr VMaz 44.6gr RL-19 on the lands not chronographed yet.
All Sako brass, CCI 200 primers. I am trying to seat to within +- 2 thou.
I have chased the 108gr Bergers and 105gr Speers around, but didn't get to a satisfactory conclusion. I shot both AMax loads at 400m at Castlelaw recently and was quite pleased with the results.
As ever these are my loads and may not work for you.
