I am going to cut my 1895 to 18" +/- this weekend, if the magazine tube I ordered gets here. My question is does anybody know if there is an optimum length of mag tube? Since a 45-70 shell is right at 2.5" the barrel can be removed in basically 2.5" increments once you determine a distance. Problem is if I use my standard 1895 it holds about 4.5 rounds and that equates to about 11-1/4" and the tube is 13-1/4" which leaves 2" for compressed spring, followers etc. If i use my CB i come up with 3" for spring and follower.
If I use the data for the standard i need an 17.25 barrel to get 6 rounds, to get 7 rounds I have to have a 19.75" barrell. 5 rounds would be 14.75" not going there.
If I use the CB measurements I need 18.25 to get 6 rounds. 5 rounds would be 16" which I think is really a little too sort.
I would like this barrel as short as possible I know the safe thing would be to cut it to 18" and cut the tube to match. It would probalby work no matter what.
BAsically I did the calcs and answered my own question. But just in case has anyone gone shorter than 18" barrel and still been able to load 6 rounds in the tube? Or on the other side have aan 18" barrel and can not put more than 5 in the tube.
