Rate Of Twist - Remington 700 BDL Varmint Special with Heavy Barrel in 22-250

[JHT]

I need to determine correctly the rate of twist for my circa 1973 Remington 700 BDL Varmint Special with heavy barrel in 22-250.  This information is critical in knowing how heavy a bullet I can use, and still maintain stability, for coyote hunting as well as other varmints.  I would like to be able to reach out and visit those coyotes with a stable slug.  I'm hoping that the rifle's rate of twist is not '1 in 12' or even worse yet '1 in 14.'  Does anyone know if Remington had ever changed the rate of twist on this model during the rifle's lifespan, which I believe is still going strong?  Thanks for the help.

A late reply, but according to my Speer manual of the period, Remington used a 14" twist rate in their .22-250s.  That is not a definative source, but likely the best you will get.  That standard twist rate will stabilize any 55-grain bullet which is really plenty for a yote.  It may work with 60s if the velocity is kept high - Nosler lists that bullet in their loading manual - but 55s are the heaviest I've tried in my .22-250s.

Lone Star,

Thanks for looking into this issue for me.  I was hoping that the twist was faster, but seemed to remember a slow twist.  Again, thanks for your input.
