The first thing that people do is google it and their first reaction is, 'holy shit, that's a $6k rifle!'. What usually happens afterwards looks something like this:
- Posts on forums wanting best caliber/rifle/build/scope/reloading setup/everything
- Gets an 'off the shelf' rifle like a Remington 700 5R or RPR in either 308 (85% of the time), 6.5 Creedmoor (10% of the time) or some random caliber because, reasons! (5% of the time)
- Shoots this rifle a little
- Posts on forums wanting a better/different scope for said rifle and ends up buying/selling/trading around for scopes because of various likes/dislikes/needs
- Buys various accessories, reloading equipment, different stocks, different rings, different rail, different trigger, different bipod
- Now wants to put a 'match' barrel on the gun even though it has 314 rounds through it at this point
- Eventually decides that he wants a bigger/better/different caliber because he has either gotten good at <500 ranges or because X caliber is better/faster/cooler/whatever
- Process starts all over again.
Most start with a 308, then go to a .260 or 7mm or 6.5CM or whatever. Then change calibers around a bunch of times and then go to a larger caliber. All while changing around stocks, barrels, triggers, scopes and every fucking thing under the sun for mutiple rifles now.
In the longrun, had you bought an MRAD that is capable of firing 308, .260, 7mm, 300WM, 300NM, and 338LM out of the EXACT same chassis while you are using the EXACT same optic with the EXACT same setup each time, regardless of what caliber you are shooting - you'd be light-years ahead money and quality wise. You wouldn't be stuck buying/selling/trading shit all day, you wouldn't have to 'relearn' a rifle each time you took a different caliber out because the optic/stock/LOP/whatever was different, none of that shit. Hell, want a suppressor? You only have to buy 1, and its for all of the calibers on your MRAD.
And if you worry that 'it isn't a custom gun', well, I've had them all, and the MRAD is a <.5MOA gun out of the box for me. Go look in the MRAD thread in bolt actions and I have a few target boards up of 5, 5 shot (one after the other, no cherry pickers) groups during load development that averaged under .6 inches @ 200 yards.
