The VMax and the Varmageddon result would suggest that perhaps I need to push them a bit harder. And maybe I'm a shyte shot as well.
Is there a way of determining how much faster my 24" would push a similar load than a 20"?
Some interesting reading for you to get a ball park on this:
https://rifleshooter.com/2015/12/223-re ... -6-inches/My 223rem pest rifle is 18" barrel. With a 50gn Zmax, BM8208 will shoot sub 1/2MOA groups at 3150fps, Zmax will shoot approx 1MOA groups at 1850fps. The Trailboss load sighted 1"high at 70m gives you a 3" point and shoot kill zone out to a little over 100m but start dropping fast from 120m.
As a comparison, a 22wrm shoots 40gn bullets at about 1800fps, from memory. The trail boss load recoils and reports like a 22wrm but can deliver a highly frangible 50gn bullet faster than a more sold 40gn bullet out of the WRM. Make for very effective and quiet pest control rifle.
