From: Q&A's, TFS 77-3, Jan. - Feb. 1989
"For bullets, I like heavy ones that are not very blunt, although there has been a lot of good shooting done recently with flat-nosed 165 gr. bullets. In .30 caliber, I start at 190 grs. and go up from there. Fit the body length to your throat, and insure the nose is engraved by the rifling.

A number of powders have been used successfully in these two cases, from RL-7 and 4198 on the fast side to 4895 and H335 on the slow side. If you intend to shoot low pressure loads, the faster numbers would be a better choice. Start around 15 grs. of RL-7 or 4198 in the 7.62x39 case and about 20 grs. in the .30 BR."

From: Product Poop - New RCBS .30 Cal. Bullets, TFS 46-14, Nov. - Dec. 1983
"I got good results instantly with this bullet [RCBS 308-165 SIL] in my .30 Rem. BR, shooting it from the mould as-cast, without sizing, and using non-crimp Lyman gaschecks with either 23 grs. of RL-7 or 264 grs. [probably 26.5 grs] of IMR-4895. When cast from linotype the bullets dropped from the mould at .303" on the nose portion and .3105" on the bands. I was skeptical at first on having only one grease groove, but this was found to be adequate with hard alloy, despite the fairly high velocities I was getting (est. 2000+ f.p.s.)."

"From my Hart 1A action with 12" twist Hart barrel, using reformed, neck turned Federal Match cases with Fed. 210M primers either of the above charges would shoot consistently under 0.7 moa. I ran several 10-shot groups at 200 yds. working up loads before our match at Wapwallopen, none of which were as large as 2", the smallest went .987, and several were in the 1.2-1.5" range a t 200 yds. At Wapwallopen I fired a 196-4x for score at 100 yds. and a 1.025 group agg. using these bullets. I switched to another heavier bullet at 200 yds., but conditions were poor and I didn't do as well with the Hoch bullets as I did with the RCBS at 100."

"Later I tried a heavier version of the RCBS bullet, lengthened by one band and ring to give a 180-gr. bullet of the same shape when cast from linotype. I shot these in a match at Fairfax and got a 196, using bullets which were not sorted by cavity or oriented, or even weighed, since I had cast them the day before the match in a new mould. I went to the match on a lark not figuring to do anything, but the bullets shot well. I did no load development, but simply shot the same charge I had with the 165-gr. ones, 26.5 of IMR-4895."

From: Moly Coat and Cast Bullets, TFS 139-9, May - June 1999
This really was a test of moly coating cast bullets, but the non-coated data was:
Eagan MX-4 (200-gr) - 31.6 - Varget - Reformed Norma 6mm BR case - Fed205M - 2024 fps - 0.8543" at 100 yds. from XP-100 Long Range Handgun.

I believe that all of these firearms were throated specially for cast bullets.

Hi

I have a 30BR that was built by Jerry Stiller on a predator action designed to shoot cast bullets. It has a 1 in 12 twist Bartlein heavy barrel (no freebore) + a Zeiss 6.5-20x50 target scope. I have done extensive experimenting with 115-130 grain GC bullets. I am now into 150's from RCBS and Lee. Best powders heve been 4198, 4895, Varget, Benchmark, H322 and 3031. I have also worked with RL-7, 4320, AA2230, W748, Ball C and XMP 5744. Bullet sizes mostly .310. I need a new chrono so velocity info is limited.

I also have done alot of work with a 22BR and .221 Fireball both custom guns.
