Does anyone have some recommended loads for this?
I'll buy some factory brass and load my own for starters.
What powder and bullet combos are y'all using?
Will a 22# recoil spring be enough?

Thanks

I have two 45ACP 1911s with accessory CorBon 400 barrels and have been shooting them since the round was introduced at SHOT Show in 1997. Living very close to Cor-Bon's HQ in Sturgis helped too.



Your #22 recoil spring should do just fine. As an aside you'll find the POI quite different from what your stock P220 barrel delivers.

I use a Corbin cannalure tool along with RCBS FL Die set #17501 (roll crimp). I also have a set of Redding FL Die set #80919 (taper crimp) but found the roll crimp to be preferred when handloading. I liked WAP for my 135 (Sierra JHP #8425) and 150-5 (various) grain loads but now that it is discontinued I use Ramshot Silhouette with the same amount of powder. Way back when I bought 1M brass from Starline. Mine are the old style with large pistol primer pockets. New stuff uses small (https://www.starlinebrass.com/brass-cases/400-Cor-Bon-Brass/). Never liked the performance of bullet weights heavier than 155 and frankly load mostly 135s. That said factory heavy fodder is fine, just never was happy with my 165 gr handloads. And yes, the extra tools and time to load this round add to the cost but you can't put a price on "doing it right" for safety.

Thanks for the info. That helps a lot!!
