So I acquired about 850 69 grain smk and 200 53 grain smk bullets from a friend. I've been researching for almost a week now and have been finding alot of mixed information about which types of powder are best for reloading. I have a lwrc, 16" barrel with a 1:7 twist. I'm not trying to get match grade performance, but I would like to have consistent accuracy as much as possible. I live in CA so the temperature can fluctuate quite a bit in the areas I shoot. I want to buy a powder that is versatile enough to where I could use cheaper 55 grain bullets in the future as well. I know that alot of the shooters here have a wealth of knowledge and would appreciate any input as to which powders would be recommended for all around use.
