45/70 250g data?
- Thread starter rommelrommel
- Start date
"...Barnes only lists two powders..." Barnes data is for their all copper bullets. They don't recommend their data to be used for other people's bullets.
There only seems to be Barnes 250 grain .458" bullets. Nobody else makes a 250 grain jacketed bullet.

Every book I have starts at 300gr. bullets.

Who would want to shoot such a puny bullet out of a 45-70 anyways??
Wouldn't it be wider than it is long?

Those are what I'm using.

Probably
Should be a fun brush round, low recoil, good for eastern whitetails.

This is not going to answer your question as I haven't shot any Barnes bullets except the old 300 gr and 350 gr X bullet in my 45/70...however have shot some 220 gr castGC out of 45/70's.
As for lack of available load data for a 250 gr. bullet and your indicating that only a few powder choices were available on their websites consider the following ... Any reloading manuals that deal in loads for 300 gr copper jacketed bullets for Marlin or Ruger type loads will work for you.
Any powder indicated that is a from "Start to Max" load in the manual for a 300 gr. will work for 250 grainers. This essentially means that any powders the manual states is good to use in a 45/70 will work regardless of bullet type... under 300 grains. Just do the load work up as if you were shooting a 300gr bullet.
If you have had good success with Re7...Imr4227..4198..3031..4895/ H335 H4198..H4227..H4895 and the list goes on..you can use any and all of these powders to find an accurate load with your " 250 " grain Barnes.
If you are hopeing for much higher velocities than standard "Ruger" 300 gr loads at about 2300 + fps you may find an increase of under 100 fps may be all you get with a 250 gr max load. Same applies if you will be shooting Marlin Load data..no huge velocity increases.
The reason I state this is that when shooting 220 gr. cast bullets useing various powders trying to see how fast these could go and even working up to compressed loads in my Ruger #3 ..no real significant velocity gain was found over a 300 grainer max load.
I found this also to be true in trying to get 180 gr. Rem.s to go faster than 240 gr Rem in my .444 Marlin. Straight wall cases and their loads behave somewhat different than bottle neck case loads useing lighter bullets.
Best of luck....

If you don't already know about the "basic principals" that any "load" for any rifle that is found to be safe with a certain weight of bullet...is a safe load with a bullet weighing significantly less .....then any suggestions we can provide you with as how to safely accomplish your request for a 250 gr load is of no value.
Perhaps you could directly contact the Barnes people and they may be able to enlighten you with more possible powders/loads that are safe in a Marlin with the 250 gr bullet. Barring that you will just have to buy the specific powders they use for load data that you have already read on their web site.
Catastrophic failures seem to be quite rampant on the internet....but have never heard of one when you use appropriate powders and begin at a safe "start load "and slowly work up to near maximum.
Would suggest these failures are much like small aircraft accidents...usually "pilot error. "

I found this data for a 45/70 with 250gr bullets:
AA-2015 From 47.0 grains to 61.0 grains
H-322 From 47.0 grains to 61.0 grains
H-4198 From 44.0 grains to 58.0 grains
H-4895 From 48.0 grains to 62.0 grains
IMR-3031 From 47.0 grains to 60.0 grains
IMR-4064 From 48.0 grains to 62.0 grains
IMR-4198 From 38.0 grains to 53.0 grains
IMR-4895 From 48.0 grains to 62.0 grains
RL-7 From 44.0 grains to 58.0 grains

RL-7 From 44.0 grains to 58.0 grains
Can you provide a source for this data....have a feeling it would help him in deciding to " believe it " and give it a try.
I found this data from Steve's Reloading webpage. Do a search for his site. Lots of good info there. If you can't find his site send me a pm and I will give you the link. I would post the link here but I don't think I am allowed to do that.... correct me if I am wrong.

Thought you'd be used to that by now.

Not quite sure why you think any of this is of value? I know it's the internet, and it's safer to assume that I'm an idiot, but I'm not. I'm well aware of the basic principles of working up a load. However, I still like to operate within the range of a published safe load, as it's well known that looking for "pressure signs" is not a reliable way of determining if you're within safe pressures.
