Anyone have a good starting charge for 160 CX's in a 7 SAUM, with H1000, H4831SC, Magpro, STAB HD, Retumbo or any other appropriate powder (not R26 as I have never seen it). H1000 tends to be good to me. I have a Hawkins Hunter mag with extended COL, so I will be pushing around 2.95 COL. 24" CarbonSix barrel on a REM 700 SA I recently trued up. Thanks in advance.

Hello, I have been trying to find out the same information. Were you able to find out anything? I was slightly concerned with case capacity. I was hoping to use H1000.
So the most accurate load I got was at 61.0gr of H1000, COL of 2.94". Velocity at 2870 FPS and SD's at around 8 FPS. Brass is ADG. Groups around 0.75". I have yet to try any other powders as it was pretty good to me. I did go up to 62.0gr with no pressure signs. It was starting to compress the powder though.

Might want to check with Longtine88 even though he gravitates to the heavies. I shoot 160AB's and 143HH's in my 7SAUM but it's an old school Model 7 with a slower twist which is fine with me as I am a SouthEastern USA whitetail hunter. Retumbo too slow. I use RL23 and RL26 but H4831sc is a good option. Sacrifice a little fps but accuracy should be good. I have no experience with CX but shoot HH's in a mono.
