A friend that no longer reloads gave me an older box of Hornady bullets. They are item# 4520 250 grain 45 Colt jacketed hollow points with exposed lead tips. They appear to be very similar to the current 45 Colt 250 grain HP-XTP bullets #45200. I have two initial questions for the more experienced here. I currently reload jacketed or plated 230 grain RN (Zero or Berry's).

1) Can these bullets be loaded in 45ACP brass? My initial thoughts are yes as the bullet diameter is the same as most 45ACP lead bullets. My concerns are that this larger dia is for a jacketed bullet that may result in a casing bulge.

2) If yes, where would a prudent starting load be with Bullseye and W231 powders in a 45ACP casing? My instincts tell me heavier bullet, less powder. I currently run 4.6g BE over the 230g RN Zero bullets, maybe starting at 4.0 grains? (I don't have access to my reloading manuals and tables right now, sorry)

Input from those more experienced is much appreciated. These would be fired out of the RIA 1911, 5" barrel.

Thanks;

Here's what I'm working with.

Based on measurements of the bullet (0.645" OAL) and seating them to the top of the crimp ring shown, I'm starting with a 1.210" COL which will be verified by a plunk test and cycling a mag full of dummies through my 1911.

Probably get away with it. I would be concerned about the loaded ammo feeding and chamber fit if they had a bulge. Besides the larger diameter and weight increasing pressure the extra bearing surface would come into play. Another issue will be the extra seating depth reducing case volume. Given all those factors I would start with pretty light loads, less than 4g.
 
If you have a 25 or 625, you could load them in auto rim cases or standard cases with moon clips and they should shoot just fine.
I don't have enough experience with automatics to comment on its reliability in feeding in that type of pistol.
 
I'd be shooting them from a 1911 nicky4968.

Titegroups - I'll be checking the actual bullet insertion compared to my 230 grain Berry's RN to see how much case volume may be changed. I don't know the length of the Berry's offhand. You've convinced me to start at about 3.7 grains Bullseye and go from there...
 
I've loaded quite a lot of heavy bullets in .45 ACPs, including the 250gr. Hornady bullet mentioned. In such "Bulffalo Stomper" loads, my preference is for cast bullets, but the jacketed versions work well, also, if one is careful. As long as your loaded rounds chamber well and the basic load is not excessive, a little bulge is no big deal. My favorite bowling pin load is a "stretched" H&G 68 weighing 240gr. over a hefty charge of SR4756 and running at 960 fps.
 
While not jacketed, I load 255 gr Oregon Trail for bowling pin loads. they are fired through various 1911's without problems. I have been using mild powder charges very similar to 230 gr lead.
