Not worth it to me.

I rechambered a factory barrel to 243AI and fired 26 rounds before I realized what a waste of time, components, barrel steel and money fire forming is.

The tube came off and a SAAMI 243 tube went on.

now,....the 6-284 makes sense,....neck down 6.5-284 brass and you're there.

I still have the factory 700 243AI barrel if anyone is interested....comes with 26 fireformed brass...:-)

I find the case trimming thing rather interesting. Trim your cases to minimum or even .010 shorter and you'll likely toss them for other reasons before you have to trim again. Better yet measure your chamber length. I have made chamber length gauges for a few of the ones I shoot and most chambers are .030 to .040 longer than published max case lengths.
