Keith: Glad the Kimber SCP is working for you. Sweet pistols, eh?
In regard to those 200gr SWC's, a proper taper crimp measuring .469" at the case mouth should let those puppies function 100% in that gun. I've got four of 'em, and all four run that load through them like snot through a goose. I found that some of my old loads put up some years ago using RCBS dies did not give a crimp that gave perfect function through various 1911's using the 200gr SWC (H&G 168). Once I ran them all back through my Dillon .45 taper crimp die using the .469" crimp, problem solved.
Another thing....all my Kimbers work fine using Kimber mags, but I've been changing out to Wilson Combat mags in all the guns here.......you'll notice the difference right away. Wilson's followers are part of the formula, also the external dim's seem to be better, as the mags drop free easily from all four of my guns. Don't get me wrong, Kimber makes primo mags, I just feel (subjectively) Wilson's are better.
Both my carry Kimbers will digest just about any commercial carry load I've ever put through them. Federal Hydra-Shock HP, Winchester PDX HP, PMC Starfire HP, Rem Golden Saber HP, Speer Gold Dot HP and Hornady Critical Defense/Duty all function at a completely reliable 100% level. All seem to shoot well too, it's just picking the most accurate one in your gun, or at this point in time, what you can find and buy a stash of to last a while.....no small chore.
After I got a Kimber 22 Conversion Unit, I find myself always carrying it on one of my alloy frame guns during rat shoots for those little sneakers that pop up 15 yards (or feet!) from the bench. Accuracy using Win Power Point HP's is one ragged hole at 25 yards. Not the equal of my Ruger Target or S&W M41, but plenty accurate for Skippy and his pals.
Looks like you're almost set to have a nice 1911 Dual-Caliber setup in 22/45......let us know how it works out.
