The Rammer 69's have done exceedingly well for me and are slicker than 69 Sugars. Those are nice "problems" to have. Maiden Rammer 69 Voyage was aboard a Krieger laced 22BR,in hasty/schit conditions. Virgin false shoulders,forming cases. Hint.
From there,I've gunned 'em in 223,223AI,22PPC AFI,more BR,22-250,22-250AI and Speedmire...all happily. Hint.
I'll whistle the Rammer 75's through some High Zoot Boltguns with magfed Smooches and extrapolate from there. Hint.
I reckon they'll be jut fine. Hint..............
