I have a fair amount of high performance data from my 24" TC Contender. 100 grain bullets were my main bullet as I am shooting West Texas White tail.
The 75 grain SIerra Jhp is a very good varmint bullet in my rifle.
I have posted quite a bit about the cartridge on the Beartooth Shooters forum.
What rifle do you have?
My barrel is a 1-8" twist. I would like to try a 1-10" twist as old writing from the 1920's and '30's has some good reports.
Greg Mushial from GMDR has a rather slow twist .25-35 WCF barrel and he shot light weight cast and jacketed bullets very well with it. He has a fair amount of cast bullet data for the Improved cartridge on his web site.
If you dont have your rifle yet consider the .25-35 Tomcat which is a mild Improvement and a very interesting cartridge.
