W-748 for .243?

I inherited two canisters of Winchester 748 Ball powder from a friend who used to reload .223. I never turn down free stuff, but I only reload .243 right now and I can't find any load data for 748. Lots of loads for 760. Is 748 not a good match for .243? I would think that with the wide selection of bullet weights available something should work. Thanks in advance.

W-748 will work in the .243 from 60 grain to 100 grains bullets, but it is probably your worst choice.

W760 is really a better choice. 748 is a bit fast. H414 is another good choice, as is, I think, IMR4350.

KS. It really gripes my gut when people make pronouncments that such and such a propellent in not suitable for such and such a cartridge, when the question can I use the powder at all.
I do agree that W-748 is not the most suitable powder for a .243 Win., but you can use it. The following is from the Sierra 50th Anniversary reloading manual. Of course, all bullets were Sierra's.

Bullet start load gr. vel. FPS max load vel. FPS
60 gr. HP 38.7 3400 41.3 3600

75 gr. HP& MK 34.9 3000 37.9 3200

80 gr.BT
85 gr SPFB
85 gr. HPBT 33.3 2800 36.1 3000

90 gr. FMJBT No data

100 gr. SPFB
100 gr. Semi pointed
100 gr. SPBT 30.9 2600 32.6 2800

107 gr. MatchKing HPBT No data.

Based on this data, it looks to me like you can at least get some fairly decent varmint loads using W-748, but the heavier bullets would be better served by a slower burning powder. Hope this helps some.

I have the Lyman Reloading guide and a Load Book for .243 that I use. Sounds like I should invest in another manual since neither of these had the data I was looking for. Many thanks for the help.

Hodgdon lists W748 loads for the .243 throughout the available bullet weights. Lyman shows BL-C2 and H335 all over the place for the .243. That tells me that W748 will work. That said, accuracy loads shown are all with slower powders.

Comin' in from left field about .243 reloading, I've gotten 3/8" to 1/2" groups pretty consistently with 3031. I've used the Sierra 85-grain HPBT and the 70-grain Hornady spire point. 37.5 and 40.0 grains, respectively, but this will blow up your obviously inferior rifle, so don't load that much! As in, start with a bit less, and work up...

Didn't see where anyone said that.

Steve. Guess I based in on your "worst choice" comment. Didn't mean to offend.
