Looking for data to give me 1300-1500 fps with Lee 340 or RCBS 325 GC bullets in a 14 and 24 inch barrel.
No, don't need rompem stompem loads I have things to do that, just want to plink and play out to 100 yards and kill a deer at 50 yards and I gots a lot of 4895 and want to do it different than the 3031 I have been using!

Nothing I have lists 4895 loads in the trapdoor load range.

Curious folks just wanta shoot something different . . . . jus cause they wanta.

Try 44 grains of 4895 with the 340-350 grain bullets for a MV of around 1400 FPS. I have found that at these low pressures, there's going to be some incompletely burned powder grains left in your bore!

That shouldn't bother him much if he is used to 3031 as it is a bit dirty also.

I have seen in print 46 gr 4895 for 405 gr as a Trapdoor load.
I tried 40 gr in my Handi rifle and it kicked so hard, I only fired that one shot for a year.

Now I have learned that 30 gr kicks about as hard as a 30-06.

I recently did some tests with Unique powder and 405 gr hard cast, to see how much pressure the rifle could take. I got all the way to 88kpsi Quickload estimate before the brass gave out. I did not have my shoulder involved in those tests.

i asked quick load about this. I don't think there is a way to bring cast loads into the equation so I put in a 350 hornady.

with the 44 grain load it predicts 19k psi and 1519fps out of a 20" barrel. This load should give about 80% case fill.

Don't know if this helps or not. good luck.

I seems to me 4895 is a little slower than 3031 and usually I have to use a couple of grains more of it to get equal velocity. I find it hard to believe 40 grains of 4895 in a 45-70 provided anyone but an elf with excessive recoil.
