7mm RSUAM Loads

Hiya team.
whats the go to powder for the SUAM with 160-162 weights?
I thought that there was some data on here with AR2209 but couldn't find it?

Ta Muz

61grns of 2213sc works in mine

67 to 68g of ADI2217

Yup 2217 for 162's for me and 2213sc for lr accubonds 150's

This shoots very well in mine. 162 amax and 150 SGK

Well bugger me! just found a partial tin of 2217 in me powder box - win!
Going to try the ELD-X 162 and see what happens - will start with 66 and work up.

Meant to ask - 67-68 with what cases? Norma necked down or Rem factory?

I run 67.5 gr with 162 Amax in RP brass, have to reduce by .5-1gr in Norma 300 saum brass. 67.5gr in the RP is still pretty warm, 68gr was bright ejector stamps on the case.

I had good results using SGKs and 2209, 55 - 60gr (work up to it obviously) some pressure signs at 70gr . Am now using RE19 with 160NABs. Have tried RE17 which was ok too but good luck finding that.

re23 spose to be good to but havnt tried it yet

Any one tried Hodgdon Superformance

there was some good advice on earlier threads - guys were seeing quite a difference using Rem vs Norma brass. Some of the hotter 2217 loads quoted above are probably based on rem brass. Start low and work up.

A long throat (allowing long ammo over all length) in a saum makes a decent difference to powder capacity, pressure and velocity.

64gr n160 and 168 bergers in norma brass

What about if the throat goes halfway down the barrel?
