    75 grain lead wadcutter .357 MAg Brass using Bullseye out of 77/357

    My goal is a very light load to use in a upgraded 77/357 shooting Bullseye and a 75 grain lead wadcutter in .357 brass. It will be used just for the fun of punching holes in paper at 25 and 50 yards. Any suggestions as to load or applicability of powder? I have Bullseye on hand and not wanting to get another powder.

    I've shot a variety of wadcutters in my 77/357, 3 grains of BE, bullets ranging from 148 to 160 grains. Shot great at 25-30 yards, by fifty yards any accuracy pretty well vanished. Good for shooting squirrels.

    Any reason you want such a short bullet?

    The savings in lead may not be worth the short bearing surface of such a truncated wadcutter. You're in round ball territory with a 75 grain WC.

    In a revolver you will find a 75-grain bullet is going to shoot a foot or more low at 25 yards compared to a standard load. If you want a low noise load with light recoil try loading a flush-seated 148-grain wadcutter with 1.5-1.7 grains of Bullseye, about half a regular charge.

    My DAD & UNCLE tried them in the early 1960's. Not really stable past 20yds or so.
    Happiness is a Warm GUN & more ammo to shoot in it.

    My experience exactly. These might do you at 25 yards, though groups will likely be nothing to write home about, but at 50 yards you'll think you have a smoothbore. I have used them in multi-ball loads and in beginner's loads for training my 7 year old daughter. I do not think they will work well for you, but all my experience is in revolvers, if you have already cast the boolits, you can give them a try. 2.5 to 3.0 grains of bullseye should give you the best results.

    I hope you load them up and give a range report on them. I would start with 3 grains of Bullseye and go from there. Would like to hear the good or bad when hotels done. thanks Todd

    I have had good results with 231, but have changed to Bullseye for the duration of the supply. At 25 yards it is just fun to shoot. Pull the trigger and a nice round hole appears with accuracy good enough to be enjoyable. My concern is this is a completely lead boolit and pushed too fast will lead the barrel.

    If one views this as a gallery load or just a grown up BB gun it makes sense. It also provides time to learn the trigger of the rifle at about 4 or 5 cents a shot and all the time smiling.

    I have tried round ball loads out of a 38 revolver in the past and was disappointed with the lack of accuracy achieved. Besides it is just fun to have holes that look like a paper punch cut them out.

    Just harmless low cost entertainment. No intent other than punching holes in paper at short range with no recoil or much noise and putting a smile on my face.

    PB234, I wasn't suggesting that you use a round ball, I was commenting that a 75 grain wadcutter is almost the same weight as a 36 caliber pure lead round ball. That's a very short wadcutter. I think you'll get better results with a longer (and therefore heavier) wadcutter that has a bit more bearing surface and can carry a little more lube with it down that long barrel.

    A WC can be very soft and still not lead the bore provided the velocities are reasonable AND it has the right lube.

    I don't think the recoil of a 148gr WC is even going to be distinguishable from a 75 grain WC when shot from a 77/357 rifle.

    My guess is the slight savings in lead per shot isn't going to be worth it and a more traditional 148 grain WC will yield better accuracy.

    I have been using a couple coats of Bills Liquid Lube with success. I only mentioned the round ball as an aside. The 77/357 I am using has been worked over considerably with a new barrel and trigger, stock, non functional metallic sights, etc. It turned out fairly OK but overall a disappointment. It was one of those occasions where you send something to a smith and get back a bunch of parts that don't work perfectly with each other.
