Jack O' Conner wrote letter to editor of Handloaler about the test Ken Water did and he gave his loads for the 270.
His load was 62gr/H-4831,Win Case,CCI mag primer,130gr Nosler bullet and that load was used 3 rifle.
2 rifles were model 70's with 22" barrel @ 3120fps other riffle 3210fps.
1 rifle was custom made with 24" barrel @ 3225fps
If you take H-4831 with long drop tube fill new 270 case and you take 130gr Nosler it won't be that compress. You take long drop tube you can almost get 66gr/H-4831 in new 270 case on the powder/cases I have.
