Hi all,
I am a bit confused wrt loads for my Browning .45-70. I was under the belief the action was at least as strong as Marlins 1895 which uses the 40,000 psi load data in Hornady's reloading book however it is a bit ambiguous when it comes to the 1886 as it states the 40,000psi loads are not to be used for antique rifles or replicas of them.
Does a modern Browning or Winchester lever action count as a replica? I wasn't sure so I emailed Hornady and the advice was to use the 28,000psi data which is opposite the advice I received from Hodgdon Technical Support and pasted below:
"You can use the data for the 40,000 psi loads in that gun but the standard 28,000 are also fine. Make sure you get a good crimp applied to the bullet , that will help with consistent ignition and help the case expand to seal off the chamber. A little blow back on a straight walled rifle case is likely going to occur at least a little bit".
The reason I have been making inquires was the last range session using RCBS 300gr Cast Gas Check bullets, a starting load of 42gr Ramshot X-Terminator, Magtech Primer and crimped using a Lee Factory Crimp Die. Recoil was very mild and there was a lot of soot on the case which was gumming up the works making it hard to chamber a round. In addition the primer was still quite rounded and there was no cratering evident.
I have also emailed Browning but have yet to get a response. I'm not shopping around until I get the answer I want I just want definitive advice, I could step it up to the maximum powder load but I still would be only using the low power 28,000psi data and potentially not getting the best performance out of my rifle.
Anyone have a point of view/advice?
Cheers,
Pete
