Hi.
I want to start loading some plinking/target loads for my GP100 357 mag.
Will be getting 148 grain double-end wadcutters and loading them around 800fps, or so.

Do you folks have a bullet supplier and specific bullet you would recommend to me?

Thanks much and have a great weekend!

Maybe take a look at the polymer coated option. I have very limited experience but have heard good things about them.

I would add my recommendation to the one above for using hollow based wad cutters over double ended for the use you state. Maybe try both and see what you prefer, but the hollow based design seem to work better in more guns.

I've had good results with the Speer 148 gr. hollow base over 2.7 gr. of Bullseye.

My pet load for .38 Spl. is the Lyman #358495 nominally 148 gr. wadcutter over either 2.7 gr. of Bullseye of 3.1 gr. of W231. FWIW, the W231 load will out shoot the .38 Spl. 148 gr. commercial wadcutter factory ammo in ever .38 Spl. I've shot. Be advised I cast my own bullets. I size my WC bullets to .359" for use in my guns., .38 Spl. or .357 Mag.

Do you size your WC bullets to .359 because that is the dimension of your cylinder throats? If not, why? (I'm trying to learn)

Yes. The .359" size seems to work best in all my .38 Spl. and ,357 Mag revolvers. If I use .358" they lead, sometimes badly and ..360 is a sometimes thing. Actually, .360" works fairly well in a .358 Win. rifle running 200 gr. bullets.

When I was shooting PPC the favorite load was a cast 148 gr hollow base wadcutter over 2.5 grs of Red Dot with a Federal #100 small pistol primer. Pushed it out my 6" GP100 at a little over 700fps with virtually no recoil, would be great for plinking/varmits.
