This weekend I was trying to get my 99 to shoot to a level of accuracy and at a cost I could be satisfied with. I think I am on the cusp of succeeding. I was loading a 180grain cast and GC'd WW, lubed with LLAlox over 12.5gr of Unique in a Lithuanian GGG 7.62 case. I seated and crimped the bullet at the second groove so that the GC would stop at the bottom of the neck so no lead would be exposed to the hot combustion gasses. The level of accuracy pleased my, 1.25 inches at 50 yards with factory open sights. I have two problems however that kept me from declaring it a success.
The group was 12 inches low, with the rear sight set as high as it would go. Fixable, I can order a lower front sight to solve that problem. The big problem however is that when closing the lever, excessive force is required as the bullet will engrave upon the rifling for about .075. I fear that if I back the bullet up to clear the rifling I will expose the lead fwd of the GC to the powder gasses and end up with terrible leading.
Any ideas?
