Mines the "A" with a 24" barrel, I hand load for it but I stuff them with the 200grn Core-Lokt's, an excellent combination!
What powder are you using? I have a 336-A I need to start loading for.

H335, 39grns, WW brass and CCI 250's
My rifles a first year for the 35 that has the "Ballard" barrel vs the "Micro grove" barrel, I usually get about 1 1/4" groups, not bad for a 62 year old rifle off the hood of the Jeep.
