My 20BRAI pushes the 55gr pills to 3900fps.
Although the accuracy node for my barrel hangs around 3750-3800...

Who did you find to make you a 28in 20 cal barrel?

I know some barrel companies that make 20 cal barrels won't make them over 26 because they can't bore them straight enough that long and still meet their standards/specs.

Most barrel manufacturers will make what you want... might cost a little more...

Correct Sherm !!!
I snuck over 4000fps looking for the 3850 speed... I only lost 2 prices of Peterson brass, so it wasn’t all bad..lol

I know Krieger won't. When I ordered both of my 20 cal barrels for my 20-250 I was going to go 28 but they wouldn't do it. Maybe some of the others don't hold their tolerances as tight as Krieger does, not sure.

My 28" 20 cal barrel has shot an .078 group are those tolerances good enough.
