sabinajiles said:Another big question is exactly how big is the bore? Is it closer to .458 or a .450? This will make a difference on sizing third party bullets. It also will probably not be possible to get a barrel drop for a full form die.
Common 45cal ML bores are basically a 45/70 barrel. .450 lands and .458 grooves. My old 45cal Accura was closer to .452 lands though and from the many reviews ive seen of CVA conversions they have been around .451 lands. So i would imagine the new 45s will be close to .451 lands. Thats great for guys wanting to shoot land riders but not ideal for HLB sabots.
What i would like to know is the number of lands. Ive seen 45cal barrels ranging from 5R to 8 groove. Again its not a huge deal for land riders but i prefer a 8 groove barrel for sabots.
