Sometime back, probably 4-5 years ago, I loaded some max loads for
my #1 45-70, with 28 gr of 2400 under 420gr. OHAS PB's. Don't know
why I did that, because, I seldom load max on anything. However, in
my recent quest to accumulate reloadable brass, I shot off 20 of those
loads from the bench. They shot ok, 5 average at 50 yds in under 2",
but boy did they pack a wallop on the rear end. The last 5 I shot offhand
and that was appreciably easier on the body.
I didn't have the box
annotated as having dac fill, but in all probability I did, as I used to use
dac fill on all my 45-70 cast loads. Any how, going back to the starting
thread, I think a 40 gr. load would take apart even a #1.
And Ben, could not agree more on the data put out there by those
keyboard cowboys. Time spent double/triple checking published data
is time well spent.
