I think you'll be unhappy with the 190-200 gr bullets if you try to run them through anything but a single shot. Also, the twist rate of 1-12" at the speed you can run them may not give as good of penetration as your looking for. (Destabilizing and tumbling)
I find that even the Lee .309" 170gr FNGC is borderline on length that will feed/cycle through my 3 l/a .30/30's. My Marlin Glenfield M30 feeds them fine, but the two Winchester M94's are draggy/hitchy due to length of loaded rounds.
Seated deep enough to feed, the base of the bullets will be below the neck exposing The gascheck and lube groove to the powder. This isn't a problem with jacketed bullets, but can cause bad accuracy with a cast bullet.
Three issues:
1. Gascheck can be dislodged from the base of the bullet. Plays havoc on accuracy.
2. A soft lube such as SPG can degrade your powder, resulting in diminished combustion.
3. Combustion will consume the exposed lube reducing its effect, also affecting accuracy.
I recommend the Lee .309" 150gr FNGC first, and if you really believe you need the extra 20gr, the Lee .309" 170gr.
I have both. The 150 casts 160gr from a 40yr old single cavity and 158gr from a now 15yr old 2-cav mold.
My 170 mold casts to 178gr. It is no more and no less accurate than the 150. Either have given 1.5" groups at 100yds from any .30/30 I've had that can shoot that good. BTW, I size to .311". Works in all my .30-31cal rifles.
For the cost of 300 bullets, you can buy a 2-cav mold, a sizing die and lube, a casting pot, ladle, and scrounge some lead and make your own. Lifetime supply if you can get a 5gal bucket of tire weights.
I've only bought one box of 50 Nosler 150gr Ballistic SilverTip RN, and one box of Remington 170gr Corlokts in the last 15yrs and will never buy another jacketed bullet for a .30/30.
I "KNOW" for a fact, the Lee 170gr FNGC over all the Reloader 15 you can seat the bullet over (1/2" below top of case mouth, ~30gr) will give about 2,150fps and cast from 50/50 wheel weight and pure lead, will penetrate a 1,000lb moose broadside as my older brother did it with a bullet cast from my single cavity 150 mold! He actually used a mix of wheel weight and range scrap. He was stationed at Elmendorf AFB in Alaska and had a moose tag, but was hunting rabbits! He said up there, you had to hunt rabbits with a " BEAR" gun as the Brown/Grizzly think a gun shot is a "dinner bell".
He passed away in 2012, and I got my mold back, and inherited his Winchester M94.
