Thanks in advance for the help. 1895GG. 18.5" barrel. 45-70. I have been shooting my 325gr soft cast gc bullets with 44.5 gr of H322 . 1800fps is just fine. I have received a batch of 420 gr hard cast gc and I have been waiting for my order of H4198 to arrive. It has and now I can't find my notes from here on recommended loads for that weight and powder. I have shot the 420 gr at 1800-1900 with the H322 and DO NOT CARE FOR IT. Ouch. call me a wuss. I want to settle back to about 1500-1600 fps. What's a "starting point " for H4198 with 420 gr hard cast that will get me into that speed bracket? I'm using Win brass and Fed 210 primers. Thanks for your time.

Don-I use 46 grains of H-322 for my 420 cast at 1650 fps.Easy on the shoulder and quite accurate.You will gain nothing from switching to H-4198.

Hodgdons list this for a 405 grain cast.
H4198- 31.0- 1459fps- 17,100 CUP
In a 24 inch barrel.

Why don't you start out at 35gr. and work up? In my gun (22 in.), that would give me about 1400fps. I'd guess you'd work up to 40gr. or so at the most. It is widely known amongst cast shooters that faster powders give optimal results at lower pressures. 31gr. gives me somewhere around 1200fps with that sized bullet.

If it is widely known,then why hasn't Marshall Stanton of Beartooth bullets caught on yet?He wrote this on his 425 grain cast, Pile Driver Junior
Regarding loads for the Pile Driver Jr., I've had best loading success across the board with H322 in the .45-70, especially when dealing with extreme swings in potential temperature. I've had great success shooting it at 52.0g of H322, WLRP and Starline Brass for a top-end load, and we've received absolutely excellent accuracy reports from folks loading this bullet using H322 from 47.0g up to the 52.0g top-end load. Most customers are settling on loads between 48.0g and 50.0g in their guns.
Humm.....Dr.A-Maybe you ought to teach Marshal the benefits of H-4198 over H-322 for cast bullets. :lol: :lol: :lol: :lol:

"Ofcourse,What would Marshal Stanton No about cast bullets" RIGHT!!!

If you look carefully, you will notice that I carefully include the lower pressure remark. That is important. I use H322 and prefer it for my cast load at the greater pressure. I use H4198 for my plinking 1200 to 1600fps. loads. Marshall definitely knows more than I ever will, and he is the one I got my loads from. :wink:

So my load of 1650 fps for Big Game, is a "Borderline" Plinking load? :lol: :lol: Bet mine will outpenetrate yours....Whoops..Back to topic!!

420 cast bullets in 45-70

Hey Don,I load my Marlin with 420 grain GC cast bullets over 40 grains of IMR 4198 and they chronied in at 1706 in a 22 inch barrel. The guide gun will be a bit slower I imagine.
What city are you in on the Island?? John

The benefit of H-4198 over H-322 is that it is far more flexible and lends itself to loads that don't kick the snot out of you. Marshall Staunton has built his reputation on full hunting loads. That's all very well for those who want full hunting loads, but many of us don't.

My .45-70 shooting is purely recreational. I don't need a great deal of power and don't want a great deal of recoil. I'm also cheap and don't like using more powder than I need or GC bullets when I don't need them. The charge of 31 grains of H-4198 is about all my PB and HB bullets will take before I lose accuracy. Truth to tell, the load I shoot the most is is 12-13 grains of Unique behind Lee's 459-405-HB.

performance question?

Don't mean to highjack the thread but it seemed time to ask the question?
I been loading both 44 cal 270gr and 45 cal 420gr FN hard cast in my muzzle loader. I have not shot any deer with it yet, did I make a good choice?
I thought there isn't a deer, bear, or elk that would stand a change if hit soildly. They are sabot loads at about 1800fps and 1700fps and the bullets don't shatter or seem the less bit brittle when shot into sand bank back stop.
