7 saum

[S96743]

Looking for load data for 154 hornadys with Imr 4350.

I loaded up some test loads for my brother last year for his 7 SAUMwith the 154gr with IMR-4350.

It shoots cloverleafs with 57.5gr. GM215M primers, Remington brass and COAL of 2.80".

Obviously goea without saying, back up a couple of grains at least and go from there

Hope this helps and stay safe.

These were with the 154gr SST

Thank you much. I was just guessing and was loading 57.5 gr to for my 7 max. I didn't realize it was that stiff of a load.

It is, we just had no pressure signs at all. If I remember correctly we started seeing signs on the primers at either 58.1gr or 58.3gr and groups also opened up.

57.5 was just the sweet spot

57.5 sounds reasonable for 154s. My Model 7 7mm RSAUM really like 59.5gr IMR-4350 behind a 139 or 140.
