Yes, I can recommend a heavy weight, spitzer or LFN, and it will shoot great, but perhaps not quite at full power, but perhaps you don'want the full recoil this gun dishes out every time anyhow? Truth is, if you use LBT lube. and send a throat slug when you place the order the bullet will probably handle as much velocity as jacketed produce in this cartridge, as cast will slip out a bit easier at the pressures of interest. (I'm believeing max recommended pressure is 50,000 psi.) At 60,000 psi, pressure with jacketed and cast are very close to the same when using LBT lube. If using any other lube work your loads up gradually as max pressure will come with way less powder than with LBT lube, but leading will come far below max pressure.
To make what I'm saying more clear. Understand that when people say the Taylor won't handle cast bullets well, they didn't have a bullet 'Taylored' for the gun, nor did they probably have LBT bullet lubricant. Without both maximum velocities will probably not be very interresting to most owners of this rifle. - In my book I show a photo of a row of spent primers, still in the30-06 cases, all showing very safe pressure, which I assume was running near 60,000 psi. The load was producing as I recall a 1 1/2 inch group at 100 yards. The last cartridge in the row is one that fired the same load and bullet except I wiped the LBT lube out of the bullet grooves and filled them with 50-50 alox beeswax, the old standby formula for many cast shooters, which isn't matched by many lubes. I had a dry Arizona mountain for a target backstop, and if that bullet would have hit it there would have been a gyser of dust, but I couldn't tell where it hit, and it certainly didn't hit the target. The barrel was leaded very heavy with that one shot and I had to hammer the bolt open with a 2x4! I feel completely safe in saying pressure jumped to 80.000 PSI and probably a lot higher. The case was ruined, with massively swollon case head, primer fell out, etc. I've taken cast in a 458 Win mag to well over full jacketed vel with groups staying in an inch, 7 Mag very close to max but stayed below max because I wanted less recoil. I may not have been able to get it to max either, because of it's high velocity.
With any high power cartridge, if you to go way over normal cast speeds take a hard look at the LBT GOP method of paper patching. It will go as high as most people care to go with velocity, with super accuracy and never a fouled bore.
