I have a 6.5 CM with 24" barrel being cut and threaded to 18" for suppressor, 8 twist. Setting this gun up for Deer to about 500yds max. and shortening up for easier movement in brush and blinds. Thinking of giving hammers a try again. Would you use HH or AH and what powder for 18" barrel? I have varget, staball, IMR 4166, IMR 4955.

I would experiment with Varget and powders with a faster burn rate than Varget for your application. As far AH vs HH, I don't have a recommendation. Have you looked in the data that GL Taylor has collected on Hammer Loads posted on this site?
Take a look at the 121 Hammer. Sta-ball should make it sing.
Short barrel and hammers will need faster powder than normal. With the HH I'd run the 110 or 124 with a faster powder and I'd lean towards the 110 as I like them running with high velocity. Maybe try Varget and 4166 as they are faster burning powders and you should get complete burn in the 18" barrel. Some of the slower powders may work but I bet they will run VERY dirty. Good luck.

Where do I find this GL Taylor data? Thanks

Call Hammer and talk to Steve.
I PM'ed him. He didn't have anything for 18" barrels. Referred me to the load data sheet on this site. But no data there for 18" or powders I have on hand. There is one with 20" and one of the powders I have, so I can start with that I guess.
What I was hoping to find out are people really seeing a speed increase with the AH's over the HH's and does that hold true with shorter barrels?
