Anyone have any experience with this combination? Bullet weight and powder suggestions?? Thanks.

I tried it and it is not worth it unless you shoot light flatbase bullets. Long bullets will not stabilize. http://www.jbmballistics.com/cgi-bin/jbmstab-5.1.cgi

Re: .243 cal. 1--12 twist barrel
I have a 12 twist .243AI. It shoots the 70gr TNT and the 75gr VMax great with tiny groups.
If you are shooting long range, then the 105 or 115gr would be better with the 8 twist. If you are shooting 500 yards and under at dogs, then the effect of the small bullet is great and the rifle shoots like a laser.
Hope this helps

Thanks Chad.. I am buildig a .243AI and am just trying to figure out a good load. I have always had great luck with the Vmax bullets in my 22-250 and am hoping for the same in .243.. Do you have any "pet" loads I might try!! Thanks a lot.!!ipscmaster

Re: .243 cal. 1--12 twist barrel
start with 42 grains of R15 and work up (using the 75gr vmax.)
you can also try R17. But 17 worked better with the 105's in my 243AI.

Re: .243 cal. 1--12 twist barrel
I honestly can't remember the exact load I used for fire forming, but I know it was the 70gr TNT bullets over a stiff load of Varget. This gave me consistent 1/4" to 1/3" groups at 100 yards and 300 yard shots on PDogs were a given.
I just finished fire forming my rounds and I'm going to use a slower powder with the 75gr VMax to see how things turn out. I'm hoping the slower powder will give me more barrel life. I'm hoping to get to the range in the next couple of weeks and work out a load. I'll let you know if I have any luck.
If you have more questions, let me know.

I have a custom wildcat that I used a 12 inch twist and was shooting up to 88 gr bullets at some pretty high velocities. 70 gr 4k fps and 87 gr vmaxes at 3800 fps very very well. It would not stabilize a 90 gr Berger hpbt but did the 88gr hp flat bases. I used powders not made anymore, Winchester Supreme and H414 in some loads. IMR4831, IMR4350, W760 and R19 as well as R22 and R23 also but Alliant powders are no longer available.
I am building another with a 10 inch twist and will be using a 90gr Sierra Bullet in it at around 3800fps and hopefully Ramshot Grand or a slow burning VV powder like N170 will work. Mind you I am moly coating my bullets and do some intricate load development to get these higher velocities.
