For the sake of brevity, I did not want to go into a diatribe on how every bullet/velocity has an optimum twist. Not stable, not accurate, but OPTIMUM.
If I was able to lighten up your day, I guess it was worth posting. I do realize AR shooters are not generally looking for match performance and those who are, might be shooting heavy bullets at long range. I think the average shooter is using 55-62 grain bullets for inanimate targets. And the BEST twist for those bullets is (in theory) 1:10 to 1:9. The 50gr should be optimum in a 1:12, and there I do have considerable experience.
Now you have to give me more than 4 words. Or better yet, help the OP with his choice. As for me, I would not buy a roll of used toilet paper from Ilion NY.
It was worth a laugh anyway... shooting 52bthps in a 6.5 twist 223 with ZERO issues, but also allowing me to shoot 90s....
The over twisting thing is over rated...
RE Rem... I buy one of their guns now and then, last one about a year or so ago. I have yet to have a complaint about anything Remington.... YMMV as lemons come along all the time from everyone out there.
OP choice.... either one would work for most purposes. Pick the one he feels best with.
