I have ventured into the AR platform and have a question about the ratching rifling vs std?
Here is a link showing the difference
http://www.shilen.com/ratchetRifle.html
Is this type of rifling inherently more accurate for heavier bullets? And how does it preform for the ligher 55gr. I'm building me a varmint gun and looking for a high grade barrel. But I will be shooting the cheaper bulk ammo too. On my property I do not have any area that requires a shot past 100 yrds , but neighbors around me 300yds is very doable. Main use will be for the coyotes and paper punching. I have another gun for the hogs, 458 SOCOM
With night vision setup for it.
Also if have the barrel fluted, will it impact the accuracy of these bull barrels?

These erector set guns give you a lot of options.

I haven't done anything with 'Ratchet' rifling so I cannot provide an informed opinion on your question.

Blue,
While I hate to mention another website while here on GTO, perhaps you should ask your question over on AR15.com. Someone over there is bound to have an answer for you.

My research indicates indicates it's only offered on the fast twist 1:8. Apparently it works good for the 80gr and up where you have a long body bullet. No indications of it being as effective on the lighter shorter bullets. I decided to go with the std button rifling for this build.

Listing other websites in posts to assist our members is not discouraged here, the main thing is to help a fellow member in need. I know that there are other websites frown upon the practice but this forum is all about helping fellow shooters.
I am glad you found info that helps with your question. I shoot a lot of 69, 77, and 80 grain bullets with the faster twist standard rifling barrels and achieve superior results with the choice. You should do well with yours in that it provides you with more flexibility with the lighter bullets too.
