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
