I thought that might hook a couple of people.
I have usually stuck to actual manual maximums in my reloading. The only time I previously flew blind was when Barnes came out with the TTX and informed us we MIGHT be able to increase max Barnes manual loads by a grain or two. The limited info on the .375 Ruger though has me searching for good data. This is compounded by my preference for Barnes bullets. I called Horanday and they were happy to give me data for Hornaday bullets, but their max loads proved pretty anemic and were not close to what I had been getting in my .375 H&H. Other sources, including this forum, listed loads but really had no justification for them being within pressure limits that I could see other than “looks OK to me”. Now I think I can read a primer, but I also think it is a pretty inexact science. The latest advice I read is from a national shooting magazine that opines that because the case capacity of the .375 Ruger is above .375 H&H, the H&H data can be safely used to work up loads up to or slightly above H&H max. Doesn’t this miss a lot of variables or is it accurate advice. The latest Barnes manual has a couple of loads, but with powders I do not prefer. I have a lot of H&H data and would love to use it if I can.
What say yea? Murphy?
