Does anyone have any good fire forming loads with any of these powders listed? The bullet is a Speer 85 gr. SBT and a CCI-450 primer. I'm not looking for max loads, just something that should cycle the action, form the case and be somewhat mild if possible. I know some of these powders are considered pretty slow but like I said, I'm just trying to burn old powder while forming new brass. Thank for the help.

IMR4064
H4350
H380
AA4064
AA4350
AA1680
AA2700




here are a couple h380 and 2700 basically fill the case and put a bullet on.  watch the case fill percent but it only goes to 50k with 107 percent so  your not going to blow anything up with either and they will probably come close to cycling.

Looking at 6X45 Hodgdon data for H335 and 60gr bullets they list 27.5gr max. So, for fire forming my brass with 55gr Dogtowns I'm going to start test loads at 27gr and work up to an accuracy load. I'll probably set the OAL on those .6" shorties at 2.13 which seems to give me plenty of bullet in the neck for adequate neck tension.
