i have a couple hundred Lee 230 gr. TL round nose bullets but they average 237 gr's. Resized to .252 and they have 2 coats of BBL on them. My idea is 5.5 gr's Unique but OAL is my main concern. 1.270 seems to be nose heavy but that was Lee manual for generic 230 cast, Lyman doesn't list a cast 230 load but a 225 gr at 1.272, their jacketed 230 load is 1.275 . Shooting them in a armscor short barreled 1911, citadel with 3.5 barrel. haven't shot it yet and have 2 box's of blazer brass case jacketed 230 grain bullets i'll run thru it first. Only other powder i have that i can find a 230 cast load for is Trailboss with OAL of 1.200. Unless it sounds wrong i think 5.5 unique AOL at 1.240-1.260 should be best bet for feeding. I'll load up 50 at each length.
