7 SAUM load data

[ElkSurgeon]

My 7 saum is just about ready to ship to me. There's a lot of load data being posted on this thread, however quite a few post don't mention primer data. What primers are you guys using?

Federal 210M

Don't use magnums. You don't need them and you will get better ES and SD numbers with regular primers

I agree with this. I don't use magnum primers in my 7 RSAUM.

I think it depends on the powder, I use magnums with slower powders most of the time but testing reveals the best primer for the application…usually.

Looking promising between 61.8 and 62.2. That is where the two rifles I have done loads for have settled in. Tried two different bullets and two powders and they all seemed to be around 61ish grains and somewhere between 2950 and 3050fps—depending on barrel length and bullets weight.

Just shot this same combo except used 210M's in a S/A build that my gunsmith had me do load development for. 61-62 was a nice node around 2800 FPS in a 22" tube. Fresh barrel so slower velocity.

Love it!

Looks great, curious what the COAL length is to the lands is for this combo?
Thanks

 

[8andbait]

Mine is a short action and I'm .020 off the lands for a COAL of 2.970 in a SAAMI chamber.
I don't have many 175's so being cautious about wasting them.

 

[ssinrdg]

Thanks for the info, mine is in a long action and COAL is about 3.066 at the lands. Trying to decide where to start with the same components.
Understand being cautious, I'm in the same boat.

175 EH's and ADG brass

N565 65.0 - 65.5 is the best node in 4 of my 7 saums

N560 62.8 - 63.2 is the best node in these same rifles.

Both are going to get you to 3,000' mark

FYI all of mine are on long actions and all like them a little ways off the lands from 0.050" to 0.065"

Hope this helps
