Powders for Medium .475 Linebaugh Loads with Jacketed (325, 400 gr)?

[rockhound758]

Hello from rainy Ohio!

I have a .475 Linebaugh and will be starting to load for it using jacketed 325 and 400 gr (both Speer and Hornady). Part of the reason for loading jacketed is my indoor range here won't allow cast and while I'll shoot outdoors some, I want to be able to shoot there as well. I've read that when using 296/110 it needs to be pretty close to max load or else danger of hangfire, etc. Hornady and Speer manuals also show 296, 2400, Lil' Gun and AA#9 for the jacketed. I'm definitely going to be loading some stout loads.

That said, I'd also like to load some medium level loads using the jacketed if possible. I'm seeing some good cast loads (light with W231 and medium with HS6) but those are cast loads. Anybody have some good recommendations powders for moderate jacketed loads for the .475, and/or suggestions on how to carefully convert over from those cast loads?

Thanks in advance and take care all.

N350 is a good 480 ruger powder with 412 gr lead but I only used 10 gr. Those you mentioned are good and hodg universal again with about 10 gr. I got my info from the internet but I have tried these and they are comfortable, fast enough and are accurate

Okay, thanks. Have you tried any of those loads with jacketed? I see lots of moderate loads with cast/lead but hard to find with jacketed and I certainly don't want to assume they're the same of course. I've been searching all over the internet and most jacketed loads are with 110 or 2400 and probably fairly full house loads, whereas most moderate loads (with Lil' Gun, HS-6, etc.) seem to always be with cast, not jacketed. From what I understand, you take a cast load and use it with jacketed and you're likely to have a significant increase in pressure, so I'm just trying to do some research. THE last thing I'd ever want is an overpressure problem with a .475 (although there's a little more leeway there than a .454 I guess).
