Boy oh boy, you guys and your hi-bred cartridges. That ain't me, but I did have Rem 700 action sent to Shilen Rifles to get it rebarreled from .243 AI to .22-250 Rem with an Alternut bull barrel. for a grand total of about $675.00 in June of 2022.
The folks there were a joy to deal with at that time.
The action already had a Jewel trigger so that was good.
I guess I'm not understanding the desire to go to .22-250 AI for just a 150 fps increase in velocity.
OK, no trimming the cases, but I set up one of my case trimmers for each cartridge I reload.
Yes, I suppose that longer and heavier, more efficient bullets for greater distance is driving this also.
The .22-250 Rem is such a flat shooter that in my world, lower Michigan, I won't need any better cartridge.
