I just added 45 colt to my list of ammo i reload. Now the issue im having is the brass is cannelured and so is the bullet......now if i press the bullet in to a col of 1.595-1.600 like it says in the reloading manual the bullet is seated deeper than the cannelure on the bullet so when you try to crimp it you bend your brass.........so is it ok to trim the brass back to the cannelure on the bullet?????? the brass now is within the limit it should be i would have to trim it shorter.... im using the hornady lock-n-load press.... hornady dies......240gr hornady xtp .452....cci lpp 300..........

It won't hurt a thing. After some firings and re-sizings the case cannelure will tend to flatten out anyway. Load the bullet so the cannelure on the bullet will be at the case mouth, crimp it, and that is the AOL you need to use.

Welcome - seat the bullet so you can crimp into the cannelure. Don't worry about the cannelure on the brass case.

Ignore what the book says the OAL should be.
You can't use what your book says, because you don't have the exact same bullet design the book used.
The correct OAL for any revolver cartridge is determined by the crimp groove on lead bullets, or the crimp cannulure on jacketed bullets.
Seat & crimp to that and the OAL will take case of itself.
DO NOT trim your cases shorter then the .45 Colt 1.275" Trim Too length to try to make it right.

Just measure your brass to be sure it isn't above the maximum SAAMI length, trim if it is above, and then seat to the canelure on the bullet and crimp. As stated, don't pay any attention to the canelure on the brass, it will iron out and disappear anyway. To reiterate, be sure to follow the recomended trim to length for the brass, don't over trim, and don't let it go beyond SAAMI.
thank you for all the info....when reloading my .41mag and 44mag all the specs in the book were dead on.......so thats why when the info in the book wasnt matching up i was getting nervous....and it cost me about 7 brass cases.......once again thank you!!!

This is often true, however I have ran into situations where seating in the crimp grove made the round too long for the cylinder. Check to make sure it is not too long for your revolver cylinder before proceeding.

Welcome to the forum...
Like said above, load the bullet so that you crimp in the bullet cannelure. Again like said above, ignore the cannelure on the brass, that's there from the factory load and means nothing when you're reloading. (just adding my voice in agreement to the above)

Fun caliber to reload!
Just check on the price of ammo vs what you're spending to make your own.
Anytime you have a bullet with a cannelure, the rule of thumb is to seat to said cannelure.
That's what it's there for.
