shooting lever revolution ammo in my 45/70

factory  325gr  in my contender, is it safe?

It is considered a lever gun level load. In my 32" barreled rifle it has a very sharp recoil, you'll want a lot of eye relief if you have a scope.

Factory Hornady Leverevolution 325gr 45-70 ammo is loaded to trapdoor pressures, as stated on the back of the box, it's good for any firearm originally chambered in 45-70.

Trapdoor? Really? I was impressed by the kick, significantly more than my 410 gr 1750 fps loads.-

thanks, i forgot to mention my contender is a 12in pistol barrel with a brake. packs quite a kick with this load. can my gun handle this load safely? i shot two deer with this load, this season , one a 8pt the other a fat doe  they both  fell where they were standing.

Yes, the Hornady ammo is loaded to SAAMI Spec which is 28kpsi.

That's a trapdoor load too by Hodgdon data, they list 405g cast at 1727fps and just 23.6kcup. Lyman lists 405g cast at 1828fps in their levergun data at just 27.8kcup which they limit to the SAAMI spec, CUP and PSI have equal values in the 45-70.

"Trapdoor" means different things to different people - and to different manual publishers.  See below, then tell me what "Trapdoor" pressure really is.

Speer.........21,000....28,000....35,000
Hornady.....25,000....40,000....50,000
Hodgdon....28,000....40,000....50,000

The SAAMI Maximum Average Pressure standard of 28kpsi, what else.
