A Question on Twist Rates

I bought a Rem. 40 XRBR back in 1999. Back then the standard offering for the twist rate was 1-14.5, with 1-16 as an option. Back then I chose the 1-16. My question is this, was/is there that much of a difference in accuracy between what Remington use to offer as factory standard and the slower twist rates that seem to be in favor today. Did the faster twist rates have more to do with what was available back then as far as ammo is concerned?

This is interesting, considering Suhl 150-1 rifles have barrel twists that range from 1:16 to 1:19. I don't know the answer to your question, I'm just throwing that idea out there.
 
One of the past threads seemed to indicate that a 17 was too slow in cool temp but was ok above like 65. Personally me and my 17 ain't gettin along period.
 
I think the gist of the question is why the 1-14 twist? I think they may have some warrant for the 100-200 yd shooters but remember folks.....RF benchrest is way, way, way newer than the Remington 40X. As a matter of fact many centerfire shooters don't think RF benchrest exists in a credible form, and even more think that shooting at 50yds is a cakewalk. Twist rates are basically, in todays RF benchrest terms, best at 1-16 to 1-17. They have better performance for different conditions and temperatures. There is also zero hardline rules on any of it. It still comes down to the shooter and ammo.

to be totally honest i find rimfire benchrest to be like shooting a centerfire at 600 yards. the fact is i like this alot more than centerfire. i still shoot centerfire, but this is much more of a pain in the butt!! i can't reload. i have to test lord god only knows how many lots of ammo a year to find what my rifle likes.

Nobody but Rem. really offered anything faster than 1-16 and 1/2 the guys at Rem. have no idea why they tried the 14 twists which were somewhat of a bust anyway.
