Yeah, I knew that, I just don't normally talk about other peoples big clangers (I'm guessing steel, I've gotta get outta this hole I'm making for myself.)

Hey 1895,
Take a look here, Lever Gun Performance Studies With the low velocity cast, one wants uniformity. Pay mind to detail, uniform primer pockets/flash holes. Trim brass to uniform length, (this gets a consistent crimp)
Point I meant to make, was the 28gr of 4198 load, recoils half again, to twice as much, as does the 14gr Universal Clays/Unique load.
An old study, by White's Labratory? determined that after bullet weight, the powder charge has the largest effect, on recoil. If I recall, they used a pair of identical bolt guns, one in 308 and the other in 30-06. The 30-06 always recoils more. Takes ten grains more powder, to launch a 150gr pill, at 2800 fps, than does the 308.
Never had a game animal ask, how sore my shoulder was! LOL
Glad you have joined the cast bullet fun.
One more point, is that with cast, (use Welcome To Penn Bullets INC., known Bob 25+yrs) the cost is $250/M, compared to $4,000/M for factory. That's right, cast 45/70's cost me 25 cents a pop! Way more range time.
As you have multiple rifles, would set one up for cast. My Micro Groove required a major sight change for cast. 6" up, and 6" left @100yds. For the Micro Groove, it "liked" the Hornaday 300grJHP and 350JFP @1800fps.
Your mileage may vary. LOL
Later, Mark

By actual calculation, the 1200 fps load with 4198 is about 17.3 ft. lbs (using 4700 as the powder gas V) and the 1100 fps load with Universal/Unique is around 11.9 ft. lbs. The powder used accounts for about 60 percent of the difference in recoil energies, while the 100 fps difference in velocity accounts for the other 40 percent or so.
This with 7 lbs. given as the weight for the rifle, which might be a little low, but it's a relative rather than absolute comparison.

In my younger days when I made my own fishing weights, I found that churches were a good source for lead supplies.
They all had lots of it on the roof and it was relatively easy to harvest.
Just a thought
