Here's a pic of my simple sorting of 140 ELD-M.. approx. +500 pills. My goto pill for range 6.5 cm small groups. This is a simple visual with no scientific method, and the 140.0 bin has been already been emptied once, so it really should be +200 pills, ie a lot more/higher than 139.9. I pick a bin to load a series from, to keep the pills within a small weight range.
Settled in on 41.50 gr Varget, F210M, Starline brass and 2.660" COL for about 3150 fps. Fired my SAV 10 GRS with Vortex Viper scope off a solid granite bench. Tried 8208 but Varget was noticeably better.
Have a brand new 10 GRS, mounted the scope & bubble level, its not been fired yet. The bolt is extremely difficult to remove & replace using the trigger depress then bolt release procedure. Only one out of ~ten tries works either in or out. Don't like to force anything, (shouldn't have to imo), but will it free up over time, or, can I help it along by slightly rounding some edges on bolt lugs ? TIA
