Hey all,
I'm loading for a Henry 45/70 and I'm running into some issues. I realize this isn't exactly precision rifle, but I'm really running out of places to ask this.
So I loaded up a bunch of Speer HotCor 350gr flat nose rounds to the Speer loading manual COAL. I ended up having to single feed these in my lever rifle because they were too long. I called Henry and asked what the max COAL is for this rifle to cycle, they stated 2.590" but wouldn't tell me how to achieve this because let's face it... it's a liability for them. I estimated my rounds to be equal or slightly less than 2.700" COAL.
In order to get these Speer 350's to seat deep enough for the crimp, I'd have to trim the brass from the standard 2.105" to 1.990". I was concerned about this option, so I looked at another bullet, the Sierra 300gr FN. In order to achieve the same COAL I'd have to trim down near the 2.010" mark to be able to crimp properly. Lastly, I looked at a bullet that you're supposed to trim the brass down to 2.040" from 2.105", that's the Hornady 325gr FTX. The FTX would put me at 2.590" with book-recommended data, but it's not the bullet I'd like to use.
This is the only straight wall cartridge I reload for and I'm fairly new to it, but I'm not new to reloading. I'm concerned that trimming the case down .100" or more is going to really cause pressures to spike. Is it common to trim the case relative to the partition location on the bullet you intend to use? I'm running out of ideas for making ammo that can cycle before I shuttle everything and the rifle. ANY help would be greatly appreciated.
