6.5 Grendel vs 300 blackout vs 30-30

[JASmith]

I may be repling to something you are not asking, but I have a 35 rem. that I load spire point bullets for in a T/C single shot, it is like a different cal. Just hand loading for the 30=30 with different bullets than normal will be quite a kick, try thst first before you spend some money

Try Bullberry barrel works -- they make a very good barrel in 6.5 Grendel. Mine is a lot of fun to shoot and I usually get better than 1 moa with almost all bullets including 140 grain versions.

I have shot a fair bit of different bullets and powders, so have some that don't do as well. N the other hand, there are a fair number of sub-0.5 moa groups in my target collection.
