Anyone load .45-70 with Vihtavuori?

[Thegreg]

Have you looked at Reloder7? supposed to be very good with the 45-70

I've not looked at Reloader 7 but will have a look. Trying to find a Viht powder to be honest, moving most of my other calibres onto it.

You don't tell us what gun you are shooting your reloads in - it really DOES matter, even with a lead bullet.

I have a Uberti Winchester Model of 1885 High Wall - my load, out to 500m - is 32gr of IMR4198. That is with a 405gr lead flat-nose.

Your 57gr load seems to me to be rather more than the recommended top load from the Hodgdon reloading manual, 26th Ed, page 479

H4198 44gr

'For modern rifles designed for high pressure loads only'

Like the Ruger No1, for instance. Or the Marlin whatever it is, but not any kind of modern replication of an older design.

You are quite right, that was a typo on my part, the 57gr was of H335. I've gone up to 50gr of H4198. That's using 300gr jacketed soft points. Still below the max load according to Nosler. For 405gr Lead heads I use 40gr max of H4198.

My rifle is a Browning made Winchester 1886, capable of handling the same loads as the Marlin 1895.

I've found a table quoting that Viht N130 is an equivalent to 4198 so might look into that a bit further.

'kay. Your 'Browning-made' 1886 is actually an SKB-Miroku-made rifle, same as mine over in OR, except that mine is in 30-06. I have the half-octagon/half-round barrel, with 'Diana Grade #1' detailing. Second-hand, from a guy who was getting the ever-living snot kicked out of him by it. He was 5' 1" and built like an elf, and may have weighed in at 90# wet.

Thanks for the replies. I have seen the data on The Vihtavouri website but it doesn't really help for the lead bullet heads I want to load. The one lead bullet they do give data for is 510gr gas checked, and the powder quantity is significantly less than the jacketed rounds.

I currently load 350gr & 405gr hard cast, without gas check. I can put a full charge of 4198 behind these with no issues and there's plenty of data to back it up. The American forums haven't turned up much because they don't use much Viht powder.

I'll keep looking!

Cheers

Using 12gr Trailboss in my load with 405gr lead works fine. Nice light load
I would not worry about it when we leave the EU should sort it out
