Load information for Xtreme Bullets 150 Gr Plated

[rjc324]

Looking for a reduced load which will produce a muzzle velocity of approximately 1500-1700 FPS. I've checked all of my load data and the majority of minimum loads I find average around 2200FPS. Any help would be greatly appreciated.
The bullets themselves are flatnosed copper plated lead bulltes designed for velocities of approx 1500-1700 FPS. I have been reloading 308 and 22-250 for about 40 years but never have I gone below stated minimum cartridge loads.

rjc324: I have no direct experience with these 'cast bullet' loads from my old Lyman Handbook. They were for 'gas check' bullets, but, may be workable with your 150 grain plated bullets.

bullet #311466 (150gr. GC) 15 grains IMR-4759 = 1510 fps.

bullet #311466 (150gr. GC) 16 grains #2400 = 1550 fps.

bullet #311466 (150gr. GC) 17 grains IMR-4227 = 1555 fps.

bullet #311466 (150gr. GC) 18 grains IMR-4198 = 1620 fps

I am always reluctant to post any reloading data and these loads are from a handbook published in the 1960s. You might want to cross check with data on the 'Cast Boolit Forum'.

The loads listed should be fine. My friends & I shoot cast, plain based bullets in our old single shots, using heavier bullets. Our normal load is 14 to 14.5 grains of either 4759 or 4227. 4759 is very hard to find & is no longer in production.

2400 was re-formulated a few years back. It is not the same as in the 1960s.

You didn't mention what powders you had available to use. Those plated bullets are still relatively soft, I think they're pure lead under the plating. Castpics has some 30-40 data. Blue Dot has worked good for me, start around 15gr.

Thanks for the input, will definitely see if I can locate any of these powders.
My current inventory contains IMR3031, IMR4064, Varget, CFE223 and ARComp. For shotshell loading I have Green Dot but I don't think that this one will work in a rifle, may look for the Blue Dot first.
Again thanks for the input I knew that I could count on your expertise in this matter.

Nothing wrong with Green Dot for cost-effective non-jacketed loads in the 13-1500 fps class. 10 to 13 grains will do the job. Of course this is pretty low-density, so avoiding double charges is critical.

Check Lyman CB handbook, 3rd edition, for verification with similar-capacity cartridges .308 Win, .303 Brit. and 7.65 Mauser. Note listed pressures. (Never accept load data from dodgy strangers!)

Thanks for the input, am trying IMR4227 first and seeing what great results I get,
Thanks again

Good luck with that. 4227 doesn't really ignite or burn well at the low density and pressure you'll probably have to employ with those relatively-soft plated bullets. Green Dot, a double-base powder with a good proportion of nitroglycerin, is more likely to ignite and burn nicely at low density/pressure.

Save the 4227 for small, high-intensity cartridges like the .22 Hornet.

These guys shoot plain-base cast bullets all the time. The goal is extreme accuracy.

Note the frequency with which 4227 is used.

Thanks Butlersrangers, tried 17.0 Grains of 4227 and it worked flawlessly, was able to keep 1" groups offhand at 50 yards.
I might try the Greendot next for a comparison.
