Saeco #955 RNFP for 1873 Lever Action

I’m thinking about getting the Saeco 955 to feed an 1873 lever action. I have RCBS 45-230-CM (it works). I’m finding out that the 1873 can’t handle cartridges that are too long nor too short. I don’t want to cut any of my brass short to make any particular bullet feed in this gun.

Does anybody know what the cartridge overall length is when the Saeco 955 is loaded into standard .45 Colt brass?

OAL. is 1.60

I shoot the 955 in CA in a 66, not much different than a 73, for OAL of 1.58 crimped at the very top of the crimp groove.
No feed problems.
I have 2 4 cav. 955's about 20 years old, you'll like it
