I have breezed through most of the posts and it was interesting to me how shooters I know SHOOT and compete suggest any newbie consider ALL the parts of the shooting process which include rifle, optics, and feeding it.
If the goal is to be good at any form of precision shooting, SHOOTING will be necessary. That means reloading and burning up lots of components including barrels.
As shooters, we have such a huge range of great rifles that can produce sub MOA with little work. In fact, we now have factory rifles that can approach 1/2 min AVERAGE even at longer distances. These can cost as little as $1K.
So the biggest question is what is the ENTIRE budget including the rifle, optics AND shooting.
At $1.00 to 1.50 per bang for F class competitive 308 ammo and the need to shoot a few thousand rds a season to get proficient, running costs approaching $4K per season is not out of the question these days. And that doesn't include travel, matches, cleaning and support supplies, replacing worn parts.
If the newbie can afford a $5K rig, $2.5K optic and then afford the $2 to 5K it takes to feed it, AWESOME. But most of the shooters I have met and helped run out of gas after buying the rig. Some even complain about the costs in reloading gear which is peanuts over the lifespan of the shooter.
a 1/2 min rifle whether it costs $700 or $7000 is still a 1/2 min rifle. Way too many shooters forget that the target doesn't care how much it costs to launch that bullet.
My recommendation to ANY new shooter is to work back from how proficient they want to be, to what they can afford to shoot over the year(s) it will take to get proficient, THEN to the platform(s) that can help them on their progress.
Chat with top competitive precision shooters and they likely will focus on needs to improve consistency and wind reading. The highest dollar whatever only enters the mix if it will actually do something to help their end result.
Also, many top dollar custom actions require MORE skill to maintain then those "lesser" actions suited to the average user.
Any shooter that wants to get good at this sport will be spending ALOT of money. The smart move is to spend it on things that help improve skill.
YMMV
