Of the available soft swaged HBWC bullets available today Remingtons are the best hands down. They fully equal the fine old Winchester bullets you used to be able to get.
With current Alliant Bullseye it takes 3.0-3.2 grs. to reach the same velocity you would expect to get with factory wadcutter loads. But accuracy deteriorates with the Hornady, Speer or Precision-Delta HBWC bullets if you try to load over 2.8 grs. for 720+/- 30 f.p.s.
The former Hercules Bullseye powder took only 2.7-2.8 grains to develop 750 +/- 30 f.p.s. from a 6-inch PPC gun with a flush-seated 148-gr. bullet, but that gets you only about 700-720 f.p.s. with current product which may not be enough to stabilize the bullet in 18-3/4 inch twist S&Ws or to reliably function the S&W Model 52 or Colt Gold Cup with the standard factory recoil spring.
With TiteGroup there is some lot-to-lot variation, so start at 2.4 grs. and adjust as needed for reliable function and velocity 750+/- 30 f.p.s. for the blockback-operated match pistols. The Remington bullets will stand up to 3.5 grs. of Alliant Bullseye for 850 +/- 30 f.p.s. without the skirt opening up or hurting accuracy if the revolver forcing cone is properly cut. This load can also be used in the Colt Gold Cup as a good field load if you use the full-power 16 pound .38 Super recoil spring.
I use the Saeco #348 double-end, bevel-base wadcutter cast 10-11 BHN using indoor range backstop scrap. As-cast bullet diameter is .360", the same as factory Remington 148-grain HBWCs. I load these as-cast and unsized, lubricating with Rooster jacket full strength in a proportion of 1/3 cup to 1000 bullets, or alternately using a diluted solution of Lee Liquid Alox cut 50-50 with mineral spirits in the same ratio. Both lubes work just as well for target loads, but if you change lubes you must thoroughly clean and dry the barrel and chambers of the cylinder and recondition the bore by wiping with a patch lightly wet with lube, letting it dry, and then wiping with two dry patches.
Cast double-end wadcutters require heavier charges to shoot well than soft-swaged hollow base types. I load 3.5 grains of Alliant Bullseye with Remington 1-1/2 primers for double-end wad-cutters and 3.1-3.2 grs. with factory Remington HBWC bullets. I load the Remington bullet flush seated similar to factory loads and the Saeco #348 double-end bullets with their sprue-cut forward, to the crimp groove with the beveled base band exposed. I taper crimp using the Lee Factory Crimp Die applying no more crimp than is necessary to completely remove any mouth flare. Excessive crimp damages the bullets and enlarges groups.
For serious target work I use only cases which were originally used for loading factory wadcutter ammunition. Wad-cutter brass has thinner walls with a long cylindrical section which extends all the way to the seated base of the wadcutter bullet, whereas +P and other cases made for JHP service loads are thicker walled and have a faster internal taper intended to increase bullet pull to improve ballistic uniformity with the slower powders used for factory loading jacketed service loads.
If your target revolver or match auto pistol has tight chambers, cases expand very little so that .360 diameter bullets will hold friction tight in fired brass until the shell head on the loading machine rotates to the final station in which rounds should be full-length profiled and taper-crimped only enough to remove all mouth flare. Unless your gun has sloppy service chambers, it will be necessary to resize the brass to prevent bullets from dropping down against the powder under vibration of the loading machine, which causes DANGEROUS variations in seating depth!
By loading the "fat" factory Remington bullets or as-cast bullets in unsized brass, and profile taper-crimping in this manner, case life is improved, bullet deformation is reduced and bullet pull is more uniform, because the brass work hardens and springs back much less when it is worked only once in profile crimping, versus when being cold worked three times in the usual method of full length resizing, expanding, seating and crimping.
Standard .38 Special loading dies work brass excessively because their dimensions are intended to resize cases tightly enough to provide a tight bullet fit with jacketed bullets. If you must load new brass or that which has been previously resized use a .38 S&W Cowboy Expander plug of .358" to reduce bullet base deformation during seating.
My loading method is to separately de-cap brass, tumble clean in clean corncob, uniform primer pockets using a carbide tool with fixzed depth stop, deburr flash holes with a No. 2 long center drill the first time they are loaded, then hand prime brass so primers are always seated carefully by feel in a clean pocket. I use the Dillon RL550b for load assembly to flare case mouths, measure powder, seat bullets and crimp. I use this same simplified process in loading .45 ACP my match ammo as well.
Using the Lee Factory Crimp die sizes the bullet only if needed to ensure that rounds do not exceed SAAMI Maximum cartridge dimensions. It does so by gentle compression f the bullet inside the case instead of reducing it by radically shear in a die. The un-sized, exposed bevel band of the DEWC ahead of the case mouth enables a positive gas seal in revolver cylinder throats. My .38 Special wadcutter reloads average sub 2-inch 5-shot revolver groups at 50 yards from Ransom Rest in long series of targets. It takes a very good lot of factory wad-cutters to beat this.
I'd have to give up shooting if I had to pay retail.
