Am I missing something?

[AL45]

I was in Cabelas and they had Oregon Trail 230 grain RNFP .45 CAL sized to .452. They also had Oregon Trail 200 grain RNFP .45 LC CAL sized to .452. I assume they will BOTH work in a .45 ACP and .a 45 Colt If so, then why is one marked .45 CAL and the other marked .45 LC CAL?

Just a guess but does the 45LC have a cannelure? That would indicate it is for a revolver.

As a general rule 45acp jacketed bullets are 0.451. Lead bullets are 0.452.
Be careful with the type of bullet (point). Flat point revolver bullets may not feed well in a semi auto.

Both bullets are RNFP lead bullets sized to .452. I bought the ones marked .45 LC CAL and they do have a cannelure. I don't know about the ones marked .45 CAL since I didn't buy them. I usually use 200 grain SWC in the .45 ACP and they feed fine. They don't have a cannelure. I didn't realize that Cannelure bullets was only for revolvers. I have reloaded for my Blackhawk for several years but have only started reloading for the .45 ACP over the last year. Why can't you use a cannelure bullet in a semi-auto?

Why can't you use a cannelure bullet in a semi-auto?

No one said you can’t, it is just that the profile MIGHT cause feed problems. For example the flat nose may be to large. You can not crimp into the cannelure for a auto that headspaces on the case mouth.

You can use cannelure bullets in an auto pistol, you just cannot roll crimp into the cannelure like you do for revolvers, and usually its not a needed thing in an auto pistol anyway.

Once the bullet weight and recoil reach a certain level, you have to use some crimp on a revolver round, to prevent bullet jump. You don't need that in an automatic.
