Hope your happy w/ the MOd 70. I have the black and blue and love the gun. Perfect balance, litewt. handy, $379w/Simmons 3-9 Bull**** scope already attached.

HOWEVER!!! I've had constant feed problems with it. I hope you don't find this problem w/yours.

If your roll your own, i'd start by going down. 2 reasons: I know the damage it does to whitetails and also have heard about accuracy probs from some.
I don't have the acc probs, but don't shoot match type stuff either.

I'm shooting 100 power pts @ about 2 1/2" @ 100yds, 3 shot group
That's about as still sa I could hold it anyway

good luck
Brad
