10mm meteorite. Nasty nasty.
I have a Colt Delta Elite in 10mm and I'll never part with it. I so love that cartridge and the firearm. I wonder what velocity could be expected from an extra .400 " barrel length. Thanks for posting
Depending on the load, probably only a few fps faster if that.
Went to Underwood ammo and was disappointed to see all but one of their loads are not compatible the DE. Something about lack of case support. Neither Buffalo Bore or Double Tap ammo mentions anything of the sort so I have to wonder about the cases UA is using. I use some DT in my DE and haven't had any problems and they are more potent than most mass produced commercial stuff.
