It hits the target lower than a 250 in a fixed sight gun or can have the same poi with less recoil.
.45acp Lyman Book Question.

Just another caliber. The regular bullet is a 250 grain or larger. It can be loaded from mild to almost 44 Mag potential. With the big bullets it is a real thumper! As arjay said use the lighter bullet in Cowboy action shooting ( I don't) Just a fun gun to shoot.

45 Colt and 45 Long Colt are the same caliber. It seems MO bullet is using the same mold with different alloys and marketing them for different purposes. Their Cowboy #4 and IDPA #4 are the same mold, just different BHN for different purposes/velocities.

Are you askign why use a 45colt bullet or why shoot a 45colt rev? For some that shoot noth calibers, the 200grLRNFP is a bulelt that can be used in both w/ good results. So it simplifies logistics.
IIRC the term Long Colt began with the army issuing the Schofield 45 way back when.. The S&W took a shorter round than the old Colts thus the terminology to identify which was which for supply purposes.
Is there and an advantage to a long Colt and are you saying the .45acp is the same, just shorter case.
Is the brass hard to get cause I would like to get one one day.
Thanks,
Jim
My calibers I shoot are 38spl/.357mag and .45acp
The 45 acp and 45 colt are very similar in factory loads,but the 45 colt can be souped up for guns that can handle the increased pressure.
No flare please
It's hard to tell in your picture exactly were the rim is in relation to the barrel shroud, but I wanted to mention to make sure that the dummy/test round case mouth does not have any flare left on it when you do your plunk check. Put just enough taper crimp on it to remove any flare/bell-mouth. You want to hear a nice metal to metal (brass to metal) clink (high pitch) when you drop the round in the bbl. I also like to rotate the round in the bbl. & feel how smooth it turns. (Practice this with a full length sized case only to see what I mean.)
My Colt 1911 barrel has very little freebore before the rifling & I have to make sure I check any new bullet I use closely to make sure it's seated properly. You want to seat it deep enough to not contact the rifling but not to deep as to compress the load & raise pressures unduely. Like the posts said, OAL is a minmum measuement for that exact bullet & each bullet's will be different & each barrel may be different yet again. I usually have to seat round nose bullets so the bullet's ogive is just about at the case mouth or it'll contact the rifling. (My Colt & S&W 1911's are like this but the Ruger's bbl. has a lot more freebore & not so critical.)
I don't have this exact bullet but I have a similar 45 Colt LRNFP-HP bullet (for my 45ACP) that when it's seated properly the OAL is only 1.100" (the hollow-point nose is short) but the ogive just clears the rifling. The case mouth is in-between the shoulder & the crimp groove, usually closer to the shoulder, for me. Once you've loaded a certain bullet & established the OAL for it, in your gun, you can refer to it next time you load the same bullet in the same gun.
Hope this helps.

Just saw this thread, so a little late.
I have shot thousands of the Cowboy #4 in my 45 ACP's. Same bullet as yours but softer. It has fed well in any gun I have used. I seat to 1.195 as others have said. At that length you can barely see the crimp groove.
