28 SHERMAN MAG

[chev4x4s1975]

I built this 28 sm and it is a shooter already 20 rounds down the barrel and it's shooting really good es&sds great build by S2i it balances really good its weighting in 9.5 to 10cpounds looking shoot 180 vlds and the 195 elite hunters with Imr 8133 or N570 all 100 pieces of brass are fired formed now.

What barrel length did you go with?
Thinking about rebarreling my 7 STW in to a 28 Sherman mag.

I'm shooting 180 vld with 83.7 grains of N570 215m primers at 3295 average 1/4 inch groups at a 100

That is moving do you remember what load you used to fire form your brass

 

[chev4x4s1975]

I used a 180 Eldm with reloader 26 but not sure where I was at for a charge

What is the barrel twist needed, to shoot both the 180 and 195 Bergers?
Thanks

1:8 is a good choice and gives you more options. 1:9 is minimum.
