Okay found an answer to my post here about what was possible with 10 and 12 twist bbls. and velocity and what was being tried in that regard.
By accident i found Larry Gibson's tests with those twists in 308 i believe on the NOE forums. Thanks for your time and results on that with the xcb boolit...very impressive, especially the 12 twist. I think that will help a lot of folks obtain a bit more velocity with what they may have along with good load tecnique.
And yes i know a 14 or 16 twist makes it easier. This spring or early summer i plan to go that route with an 06 in 14 twist with the xcb boolit and beg goodsteel to build it for me using the xcb reamer for a good tight fit with that boolit.
Should be a fun project and just use some of the 06 brass to neck up for my 14 twist 35 whelen too.
If anyone is interested in getting a bit more from a 10 or 12 twist they have on hand "right now" in 30 cal. you may find Larry's tests on the NOE sight very helpful. At least i did.
Not trying to start an argument on twist rates, but this is a discussion on high velocity and i'm interested in just what can be done with all of them.
As has been mentioned in one post here i hope the continued interest and testing for high velocity here on this forum results in more interest from the factories in putting 14 and 16 twist bbls. on some of their rifles.
