No RD I never have.
To be honest I was thinking that 28 Nosler would match up well with the real heavy 7mm bullets,say nothing less than the 160's 162's...the 175-180's...maybe even the 195 Berger if you're inclined that way.
The case has the capacity to really drive those heavy bullets and I think that's where the advantage is.
Anyway that's how I'd go today. I shoot the 162 Amax a lot in the Mashburn but have yet to use anything less than 160 in that case.
