Muzzle velocity please:
I live in South Africa and therefore do not use the same powder as available in the US, therefore cannot use your advice on powder vs bullet gn - but need advice on best muzzle velocity for accuracy on:
Howa 1500 synthetic stock 3006,
Barrel: 1 in 10" twist,
Barrel length: 20",
for 168gn boat tail bullets.
(All testing done at 100xmeters)
I started testing 155gn Sierra Comp bullets, but it produces flyers,
I have already tried 175gn Sierra Comp bullets and got it down to 5x shot 12mm(I do not understand your inches thing - sorry) grouping,
180gn gives me no grouping worth mentioning to anyone alive, so it stand to reason that going over 180gn is no option.
Due to the different powders available between US & SA my only option is to test at Muzzle velocity.
All help welcome.
