My gunsmith have two rifles built on ruger no 1 for sale. Both have a weight of 10 pounds with a 26" heavy barrel. One of them is in caliber 45-70 and the other is in caliber 45-90. The cost is the same for both.

I don�t know what to choose. I plan to use 350 grains and 405 grains bullets from Woodleigh and like to get 2200 fps and 2100 fps out from it. I don�t know if it�s possible to reach this out from a 45-70 without to get to much pressure. Maybe there is not place for powder enough in that case.

I know that the ruger no 1 is good for very high pressure, but maybe the caselife gonna to be very short. If I choose 45-90 I can use starting loads for 458 WM and get very low pressure and reach those velocity.

Anyone here who knows about load data for those bullets and 45-70 or 45-90?

Wich one shall I choose?

You may find brass for the .45-70 is easier to get (and less expensive) than for the .45-90. Also, my Lyman Reloading Handbook, 48th Ed. lists 2,152fps as the max. velocity from a 24" bbl. with a 350gr. jacketed (flat point) bullet. They used a compressed charge of 58.0gr. Vihtavuori N 133. Btw, although Lyman does have loading data for the .45-90, it is for lever actions, not the Ruger #1. Hope this helps your decison-making, ...Maven

This is what Starline says about .45/90 brass.
Quote:

45-90 - 45-70 based case 2.4 inches long




The price for 250 .45/70 brass is $87.00, but the price for 250 .45/90 brass is $179.00.

It may be possible to shoot .45/70 in the .45/90. I shoot .38 Special (1.155" brass) in a chamber that also shoots .360 DW (1.41" brass). That's close to the same difference in length between .45/70 and .45/90. The long jump for the .38 doesn't seem to matter a whole lot. If it would work, the .45/90 would give you two options on what case you can use. Ask the gunsmith about it.

You can get the desired velocity from the 45-70. Try Reloader-7, you won't have any problems getting there. The rifle will slap you around a little, but you will get there and have fun doing it.

At those pressures/velocitys in the .45-70, you're only going to get a couple of reloads at most from a case before the neck splits.

The 45/90 in the Ruger #1 with starline brass will give better figures slighlty than the 45/70 with a tad lower pressure. Just to be different go for the 45/90
