30 sherman magnum

[elkaholic]

I thought it was odd too. I weighed it twice more to make sure I did not mess up. ADG was 95.7g H2O

I just went up and measured another one 97.4
Is yours a 30 or 28?

 

[Copper Basin]

Mine is the 30. Maybe I have an odd case. I will test another.

 

[Copper Basin]

I did 2 more. Got 96.3 and 96.6 for 2 different ADG cases. I think these last 2 are more representative of H2O capacity.

I just measured 1 case, 6 firings on it. 30SM (ADG) and got 97.4gr H2O with a FX-120i.

Fire form load.
200 yards 3 shot sub 8lbs rifle.
Wasn't even a fluke I kept shooting and the group stayed that tight. Maybe I try to hard when I want good groups this was just settle and shoot.

Does that brass seem about right? I didn't do a super stout load and hoping it formed well enough.
Gonna be pushing some 214 hammers through some critters this year.

After about 3 firings on that brass, it'll be right.

So are you saying it will take a full 3 firings to get it we're it needs to be? I've never heard of that. I guess better question is will I have to redo my load work after the 3rd firing or is it just very little gained after first firing?

No not likely. It'll just mirror the chamber perfectly after 2-3 firings. First is not quite tight to it second typically is but not always. By the third firing, it's perfect. Most times two but three to be safe. No change to load data

With it shooting like that, just go hunting!

 

[snox801]

Thanks, ya I think it will shoot ok.
Just thinking with how good it shoots I'm gonna be disappointed when final load is done. Got to give a shout out to pierce engineering. Second rifle they have done for me and both have shot amazing. Plus they are about as easy to work with as you can get.

Wasn't aware Pierce also built rifles. Full service gunsmithing. Good to know
