Hi all.
I am looking at having a barrel built that is a light weight and 20" long. I am looking at what twist rate it should be.
My 16" Alexander Arms barrel has a 1 in 7.5 and it shoots great.
Shilen states that a 1 in 9 will take care of bullets up to 130 gr. The heaviest bullet I will use in the Grendel will be 130 gr.
So what is the big difference about?
Thanks for any information you can offer.
