I have read that the only reason they went with 1/7 was to stabilize the tracer round.
But then we have all this 77, 75 and 73 grain stuff now and one would think the 1/7 would be better than 1/8 but I just don’t see it.
What I do see, and it may be a fluke but none of my 1/7 guns like the Hornady 75 HPBT ammo but 2 of my 1/8 guns and 1 of my 1/9 guns just love it.
And my 22-250AI bolt gun has a 1/8 that handles the 88 grain ELD’s just fine but obviously with more velocity.
