Re: .17 rem 37 bergers?
jax338, The others are correct, and many (including I) have tried the 37 grain Berger, and found that a 1 in 9 will not stabilise it.
History shows that a 1 in 7 twist will stabilise and shoot it accurately, as long as the velocity is kept below about 3,450 fps. Push the velocity above 3,450 and groups open up and the bullet will often come apart.
Walt Berger in reply to my letter in 1997, advised that his 37 grain VLD were like the other Berger VLD bullets, and were designed to operate in the 3,000 - 3200 fps window where they gave best accuracy.
The REM 700 in 17 Rem usually has a 1 in 9 twist, and should stabilise bullets up to about 30 - 32 grains in weight. My suggested options to try would be: Hornady 25 grain Vmax (BC .235), Berger 30 grain HPBT (BC of about .230), and Todd Kindler's 30 grain VLD has a BC of about .270.
I don't want to be a doomsdayer, but from personal experience I believe that a good custom stainless barrel is necessary when using the .17 Remington or a larger wildcat case, as barrel fouling was excessive in the three factory 17 Remington barrels that I tried. Good luck with your .17 Rem. Brian.
