Thread: New build 30/284 Remington

1 in 10" is unusually fast for an NRA barrel ,especially if it's a Din vintage one. Most as KG says average about 13" with 12 being as fast as they tended to go.

It might be 1:12, I could be confusing it with some of my other .30 cal tubes. I will check. However the point I was trying to make is, that with the extra velocity from the larger case you maybe able to stabilise some heavier 180 gn pills, and it is worth loading up a few flat base ones to test it out.
