If it helps you any, I built my .240 on a "budget" most would say. I bought a Mcgowan barrel that was a #3 24" 1:8. my action is a Zastava m98. After doing my own work, trying the action, reaming the chamber ect.... After glass bedding and (a lot of) load development, I found that because of the weatherby free bore and the high velocities which it shoots, it WILL NOT print any Berger bullets under 1.5" at 100 yds.. (But I have a 300 wby mag that puts 210 burgers at .25" groups all day....?) anyway, I found that it shoots flat based bullets very very tight. I went with the slightly less accurate load (.41" @100) with 105 gr. A-Max. I'm pushing 3,307 fps with h-1000 but only get 5 reloads before showing signs of case-head separation...
Hope this helps, I'd just like to put in my input that buying a higher quality barrel would have probably saved me time and a lot of shooting... (Have a 7wsm with Proof research barrel that will shoot anything 1/4" @100)
