If you will search my past posts you'll find a thread I started on 38 special wadcutter loads with data , targets etc. For best results use a quality swaged not cast HBWC . Best is the Remington 148 HBWC , Zero or Magnus 148 HBWC , Hornady 148 HBWC . Speers are the worst as are Precision Delta . Any mild SP primer will work . Powders that'll work nothing faster than Bullseye ( ie Clays , N310 , N100 etc. ) nothing slower than VVN 340 . Once cases have been fired in your 52 instead of FL sizing , deprime them & take a Lee FCD . Take the guts out & leave the carbide ring . Use it to size cases . It'll work cases less & not reduce them down . Bell case mouths just enough to start bullets without cocking . Seat flush with case mouth & crimp . I use a light taper crimp to .369 . I prefer Remington cases as walls are thinner & easier to seat a HBWC without reducing them down in size . Mine prefers 3.1 - 3.2 W231 with Rem 148 HBWC , Fed 100 primer . 2.7 - 2.9 WST , 2.7 - 2.9 Bullseye or Acc #2 have been used by others . Velocity envelope is 700 - 800fps . Do not exceed 800fps or 3.0grs of Bullseye or you'll blow the skirt of a bullet . If that happens & you pull the trigger again you just bulged your barrel . If you don't see a hole in the target , noticable change in report or recoil check & make dang sure there's no barrel obstruction before you pull trigger again . Wonderful guns but fincky about ammo & technique . Some trim all their cases to 1.145" which allows a smidgen of lead to be proud of case mouth & claim it helps with feeding . 25yds & shorter with a load it likes & shooter does their part a 52 is hard to beat . At 50yds a 38 special will hurt your scores much more than help .
