Don't know if it will help ya much...
I have a 20 inch barrel, with a heavy magnum profile on a Ruger 77 Mk2 action, chambered in a 20 Practical...
Don't think you'll see much velocity loss, if ya do, maybe a click or two on your scopes elevation will compensate for it...
and if you hand load, one thing good about a 20 Practical, is there is still bullets available on the shelves at local stores..
same in 17 caliber... that is why I am putting together a 17 Fireball also...
Thanks for the replies.
I hand load and use 40 gr Vmax and 34 grn nosler, both going around 4,000 fps.
I'll chrono the rounds after I shorten it and see what happens.
I found an article about shortening a 20 practical barrel and it's effect on velocity.
At 17 inches, it had less velocity spread, but was loud and they stopped at 14 inches of length, because the report was unbearable.
