Ben--when the Lee bullets get boring and stale for ya, I have just the casting to re-awaken your interests with--a Lyman #462560. It even has an OEM Lyman HP pin, if you were so inclined.
I ran most of these at 1100 FPS through a Ruger #1 (7-1/4# rifle......) and the recoil was noticeable but still civilized. Having a Ruger #1 is just plain darn dangerous, though--sooner or later, you'll want to gallop that horse and give it free rein.
Mistake.
I ran these to about 1500-1525 FPS through the #1, and I do believe that my shoulder blades collided due to the recoil impulse. I had 20 cartridges loaded, and after sampling 3 I elected to break the loads down to components--return same to stock--and melt those 17 monsters into something useful--several dozen 9mm bullets, IIRC. Run to their full potential, the user could likely harvest an M1 Abrams or C-19 cargo plane humanely with these bullets.
