Not sure what you're saying is laughable but if it's concerning the soft point comment I'd agree. Wouldn't be practical of course but an uncoated nose it would seem would logically expand better than a fully coated bullet,just an observation.
I would assume you are not a huge fan of these methods. Personally I tumble lube with Lee liquid alox and find it works well. Always looking at different methods though.
Its been my experience with cast lead bullets that unless they are almost pure lead soft, they won't expand anyway. I have a Lee single cavity mold #90491 that has a hollow point attachment on it. It is just a normal flat nose bullet otherwise. I cast some bullets out of pure Linotype and loaded them up for my converted Siamese Mauser in 45-70. They are really nice shooting bullets and can take some pretty amazing velocities without leading. I had the opportunity to try them out on frozen beef carcasses in a rancher's dead pile. At ranges of 20+ yards, they just sailed right on through into the dirt wall of the pit. Even after penetrating the hard frozen dirt/clay, they held together with little or no expansion. They were perfect for shattering boulders.
Ok. I cast some more up. Half wheel weights and half Linotype. Still to hard, no expansion at all in the frozen carcasses. The bullets would penetrate both shoulders like they were jello. Recovered bullets still showed no expansion.
Next, I tried straight wheelweights. Finally, the bullets actually expanded but still went through both shoulders. They certainly didn't show a nice classic mushroom shape, more like a bullet recovered in an animal with SP jacketed bullets at extreme ranges. A bit of petaling.
Ok, half pure lead and half wheel weights. Finally, the bullets mushroomed in frozen carcasses. I can only guess at a 7-8 BHN.
The velocities on all of these bullets was kept to 1450fps and I used Lyman Moly Lube on the bullets. Good stuff. Almost no lead fouling. Bore was easy to clean.
I have a NECO moly kote kit. Maybe I should try coating some bullets with it to see how they do.
The moly coatings I applied to jacketed bullets were a pain in the butt. The bores needed to be seasoned but they still fouled. To clean it, the moly seasoning had to be removed. That stuff is tough to get out.
Maybe the lower temps and pressures associated with cast bullets wouldn't be a problem. Anyone else tried it????
Also, has anyone used BORE COAT in cast lead barrels??? It works like a charm in barrels shooting jacketed bullets.
