    Win 748 and cast boolits

    Has anyone had any experience with loading 160 gn cast using Win 748?

    I think the OP forgot a tiny bit of important information!
    Hell, I was there!

    Hmmm. I'd guess a 30 caliber rifle...

    The OP hasn't signed-in since yesterday. Perhaps later today we'll get some more information.

    Perhaps he means any rifle. I have but not with 160 gr (303 Brit). I was testing it with paper patch, hoping to eliminate boolit base peening. It worked. Accuracy seemed to be promising initially but I haven't followed up. Too light a load doesn't burn well so velocities might be on the high side for a lighter cast boolit (I used 194 gr) by the point the powder charge is sufficient to burn properly. I was also worried about too small a powder charge in the Brit case so I used a filler (wheat germ). Proceed with caution!

    I use it with 150 and 165 gr. bullets in a .308W but have never used it with cast.

    I've shot a lot of 311-291 and 311-041 boolits in 30-30's with 748.

    Yup--what Glen said, same info here.

    ETA--I back the data off about 10%-15% of what is listed for jacketed bullets of similar weight, though there is little reason to do so other than to moderate velocities a bit. A #311041 cast as a Bruce B Softpoint did some impressive work on a formerly VERY healthy coyote for me in the recent past. It started out at 1800 FPS over 28.0 grains of WW-748 (IIRC) and went DRT at 115 yards. I have used this weight with #311291 and c. 2008 added #311041 to the tool assortment. On paper, I can't choose a favorite between them. Cast as BBSPs, I doubt that it matters in the game fields. Place them right, and you'll be busy with venison prep in short order.

    I don't paint bullets. I like Black Rifle Coffee. Sacred cows are always fair game. California is to the United States what Syria is to Russia and North Korea is to China/South Korea/Japan--a Hermit Kingdom detached from the real world and led by delusional maniacs, an economic and social basket case sustained by "foreign" aid so as to not lose military bases.

    Works just fine in a NEF 30/30 with a GC 165 grain

    Used 748 in full loads for 30-30 and 30-40 and 7.5 Swiss. With a scoped K31 I shot my best group with cast 5 at 100 yards under an inch. If you mean one of those I have data.
