I'm a long time reader 1st time post. I've learned alot from you folks in the forums, so much so I am finally having Rem 700 .243 re barreled to a 6BR by Jim Hart after years of shooting factory guns. I have an old Ruger M-77,tang saftey),22/250 I've had over 30 years that is my winter walking gun for fox and coyotes. I want to re barrel this gun also but it has a short magazine box that wouldn't allow me to seat my bullets out to the lands if I want to use it other than a single shot. Seeing as I have a 6BR coming I wanted to play around with another caliber and was thinking of a 22BR. My question is, can I use my 6BR dies,Redding competition) with an appropriate neck bushing or do I need to buy a completely new set for the 22BR? Also if I do go with the 22BR, what twist would you recommend for 50-55gr bullets at 100-300 yards. Thanks for sharing your knowledge with a newbie such as myself,Marty.
