I am looking to bild me a new .260 Remington on a FN action and was wondering if any one has used Polygonal rifing in a rifle .. I was looking at a 1-8.5" twist Pac-Nor and seen they had that option and was wondering if any one has used that type of barrel on a rifle befor.. I know that in hand guns they are very accurate... I am not going to be using cast bullets.. and was thinking of a 1-8.5" for the range of bullets I plan on using 100gr to 160gr
My wifes H&K 770 in .308 is a polygonal bore and it shoots well, but I don't know how cast bullets would react. I do think thye shoul dbe very good as the bullet is distorted somewhat less, differently for sure.
Ask the barrel manufacturer.

Cast bullets are not recommended for polygonal rifling. I think the care in manufacturing will make the difference -a good barrel is a good barrel egardless of the rifling.

Try to look unimportant. Your enemy might be low on ammo.

I am strickly going to be using Jacketed bullets and I only use Pachs and Buctches bore shine or shooters choice.. No bushes abd no lead bullets for me.. Pac-Nor says they work very nicely so I am thinking of taking a chance and try it out... Just realy hard to make up my mind that or a 3 land 1-8.5"

David Tubb who has now earned the national high power championship 11 times now Schneider polygonal rifled barrels. After reading through what he has written on the subject, I would summarize it by saying that he believes they offer advantages over conventional barrel rifling in high power competition.

I would think the diff between the across corners and across flats would be greater than the depth of land / groove rifling. Interesting. Thanks, BL.
I don't know if it was the first, but the Whitworth rifle was patened in 1854 and had a poly barrel. Now you can't use cast bullets in one? What jacketed bullets did they have in 1854????

I used to have an HK sporter in 22wmr It shot into a half minute pretty much always.
I own a WR double rifle from the early 1860's, it's a sixteen bore rifle with Whitworth patent (polygon) bores, complete with patent use number on the barrels. It's a brute.
