I took a cheap Savage donor (12FV) and dropped it in a GRS stock with Accurate0mag bottom metal for AI mags. The barrel is a Criterion 223 Match (.090 free bore). Throat is too short of “optimal” chambering of 88/90, but it’s done 195-6X at 600y with 88 ELDs and I’m seeing speeds of nearly 2700fps with that load in a 26” barrel.
I think a cheap 12FV donor is a good way to go, My build cost:
$320 for new 12FV
$350 for barrel
$550 for stock
$150 for bottom metal.
It won’t run with a 223 FTR rig, but it’s close enough for the cost and the main limitation is the fact that I’m the shooter. In better hands, it could easily be a consistent 190+ rig instead of my mid-180s avg on an F class face at 600.
Find a used Savage donor, rebarrel with a prefit set up for the match bullets (Urbanrifleman’s ISSF barrel is a great choice) and Bob’s your uncle. No better bang for the buck to 600y can be had IMO.
And now I offer a counterpoint to my own post:
Build a full custom in 223 on whatever setup you want. The real cost of a premium custom action is free. They will keep their value and essentially never wear out if you care for them.
Then you can choose exactly the stock you want (700 footprint or better), and you aren’t limited to the Savage trigger.
The real cost of shooting is the consumables. Bullets, powder, barrels, etc. The custom action and stock and such are only expensive ONCE.
Will you shoot 2000 rounds through the rifle in 20 years? Congratulations, you just paid for a $1000 chassis. Another 2500 rounds? You bought a nice action.
Barrels are consumable like everything else.
So while I’ve done the donor savage option and it’s pretty cost effective, I’m of the opinion now that if at all possible, buy the action, trigger, and chassis or stock that you want, regardless of what it costs, because you basically get to use it for free decades if you want. They don’t wear out or break.
What’s more, the joy of shooting a nice custom action is something you buy once but enjoy thousands of times— every cycle of the bolt, every pull of the trigger is return on a one-time investment.
So the advice I would give to my younger self just getting started is:
1) go cheap the first time so you know what you want to do differently next time and you’ll appreciate the difference
2) Never go cheap a second time. Buy whatever action, stock, trigger AND SCOPE you think you’ll ever dream of. Because they are basically forever things that you will back every time you shoot.
