Just curious to what others use. I’m thinking 22gr of h110. Looking for other thoughts. Not using hard cast, just 180gr XTPs.

I like 20-21 gr. H4227, for some reason

it performs much better, top speeds up with H110/296 in the .356 GNR ctg. I have no explanation, it just does. It is really a lot for stable and consistent. However I still use WW Mag marked primers ("For Standard or Magnum Loads" - on the box). I was getting 1500-1550 fps from my 6.5" Ruger BH.

Actually I begin by looking over old .357 Maximum loads and work my around them. 1680 does well too but I have not chrono'd them.

....I got impatient and loaded 20. I was bored and did some experimentation. I also loaded 20 rounds of 300GNR the 100gr xtps over 18gr of 2400. Had a WB experimentation moment!

Id listen to these guys about 21 grains...

In a revolver. I was using my Reeder Rolling Block with those bullets seated to the rear cannelure. That definitely makes a difference.

I was just referencing the cartridge and bullet combo.

Already decided to pull them and start at 20 gr

every gun is different. For some 20 grains might be

max, for others 22 might be. My 2 revolvers in 356 GNR both like 21 grains for jacketed and lead.
