Be shooting a 22 and a 20 probably by the 1st of the year maybe sooner just as my conclusions with 45 Cal came to the 18th twist and it's versatility, I believe in 50 that the most versatile twist is going to be 20 or 22 but I have to prove that, I believe the fast twist 50 cal is going to solve a lot of my own struggle with 44 cal bullets in the green sabots,, between what is available in 452 and 429 and 458 bullets the choices will be endless and I'm not even considering those Fury 50 cal bullets and other such as Hawk I want to be able to shoot all of the standard 250 grain bullets that we shoot in Black Harvesters off the shelf into less than an inch preferably around a half inch or less and I want to be able to shoot up to a 400 grain Fury or Northern Precision 452 bullet in plastic there are some excellent 458 bullets also my plans are once I find that sweet spot in the twist to turn around and put together another three or four rifles again I don't accept the results of one rifle whether it's mine or someone else's I hope El Diablo and others join me the next few years come on let's make things better!
