The M24 is great if you want a piece of history. After that, you are certainly not doing yourself a favor if you plan on blowing $2,900 that particular way for a target gun. The ergonomics aren't anywhere near what you can get these days, and the accuracy from one isn't going to blow your socks off.
I have an M24R for the history. I got it back when there were quite a few on the market for a decent price ($2,100 rifle only). Arguably it has a little more collector value than one with new parts, but shoots just the same as the new ones because the action and barrel are new.
Mine is a solid .9 MOA shooter with FGMM, both in .308 and 7.62x51...I never really checked to see if Federal actually loads these two differently or not. At least the .9 was extremely consistent.
It took damn near 150 rounds, but I finally found a handload that will keep groups down to .5 - .7 MOA consistently...occasionally throwing a sub-half MOA group, but not too often.
For about $3,200 totally invested (Leupy Mk4 M3 purchased separately) I'd have been a bit grouchy about the accuracy...but again, I have this for the history. For that, I'm not disappointed.
