It's a conventional lube groove configuration heavy blunt nose gas check boolit designed to stay out of the 7.62x52 powder space. Tumble lube corrugations are there on the bore riding surface to ease seating into the rifling and give a belt and suspenders approach to lubrication. Looking forwards to seeing how much I can push them.
Is that bullet prone to YAW at any distance?
That's alot of bullet, but I love the idea.
Good Cheer ; What does that boolit weigh? -06
I have had good luck with accuracy with the NOE 310-167-FN-AK3 Lubed with White label's Caranuba Blue gas checked. Using 95-2.5-2.5 alloy
and pushing it with 17.5 gr 2400. The rifle is A ReM700 with a 1-12 barrel.
Is that Lyman 311041 still in production? Otherwise I'm thinking the RCBS 150 gr. RNFP. Keep the weight and recoil moderate for a 11 year old kid to shoot.

Another RCBS 180 FNGC. Has been excellent in all our caliber .30 rifles to include Garands, M1A's, Kel-Tech Bullpup, 308 Israely 308 Mauser, and all our other bolt rifles.
But Planeguy.... your AR has those feed ramps that are going to teach you what will feed... Large FN types could be a real issue. I would call the factory and ask them.

I'm not using it in the AR to start with. Getting the GS an entry level .308, either a Ruger American or a single shot Henry if I can find one. For myself, I thought about the AR and decided there's too many liabilities trying to use traditional cast boolits in it, at least while I'm starting out.
I'm going to follow this thread. I'm getting into 308 casting myself, mostly for plinking, but I've been thinking about casting some white tail hunting rounds as well.
+1 for the 311041
I've tried the 311041, saeco 305 and rcbs 180 in my .308s and there isn't any real world difference between them. My preference has been for the saeco merely because it casts perfect boolits effortlessly.
No hogs here but at .30-30 speeds they're pretty decisive on deer with ACWW
Miha makes a .30 180 grain with a larger meplat. I haven't had any deer cooperate yet.
I don't believe there's any bad choices here.

It's my 100 yard practice bullet for my Ruger Scout (can't hunt with lead here). Accurate and detonates milk jugs with authority.
WWJMBD?
In the Land of Oz, we cast with wheel weight and 2% Tin, Man.
The dimensions on that mold are made for an odd duck of a 7.62x52 bolt action with a .303 bore and .310 groove diameter. I think the Israelis are responsible for having done that but I'm not certain.
So any how...
I'm pretty certain the mold could be ordered from Accurate with diameters suited to a standard .300 bore and .308 groove. Or, for .303's. Tom is really good to work with on tweaking diameters.
But, that said, the length is also suited to how cartridges feed in my rifle. When they come up out of the magazine the nose of the bullet skids off of the 20 degree shoulder in the chamber, centers itself up and is inserted into the bore with a very slight engraving on the tumble lube ribs. Seems to me that it should work that way in just about any bolt gun but there are differences in bolt heads and maybe there're some it wouldn't. I just don't know.
Another passing thought, surely it couldn't be very difficult to program the machine to reduce the number of tumble lube ribs and thereby the overall length.
