I might try out both techniques to find out if its worth going the 6mmBR way.
How many cal. expenders would you recommend for the necking up process? 7mm, .30 (and .338) I guess?
I think I'll be able to share results somewhen in may to june since I'm just doing research at the moment because of lacking the money for such a project right now (unfortunately it's not the only expensive hobbY I got
).
However I already got a promising "baseline"... a Savage SS target action
