Did I send you any RCBS 200 FP?

I dont have the Lee mold just the RCBS.

I sized 20 down to .356 yesterday and got side tracked organizing brass... ;)

Reloder 7 and A1680 are both a bit slow. You'll give up about 100-150 fps at a case full to the H110 or A5744, though your pressures will also be lower at max density. 2400 is actually not a bad choice, you give up a little on the velocity end but it might agree with a 16" AR better. There's just not much you can do with this tiny, square case.

Old thread but I'm shooting a pair of ruger bolt guns in legend. One a standard carbine another a 22" " go wild "
With either the Lee 200 or rcbs 200(sized. 357) and 12g of 2400 groups are 1-1.5" at 100 yards with a few larger and a few smaller.
These are seated to function in the magazine.as much as I prefer older traditional guns and calibers I fund this quite a nice gun/cartridge for cast bullets.i haven't tried really hard to fine tune a load as this accuracy is all I need for my steel ringing/clay bird busting at our range.

groups shown typical. Not worst or best.

I had 14g of h110 in the measure so I tried it with the Lee.it shows promise but needs a bit more powder I believe.i was getting groups 3/4" wide x 2" tall
