i have not spent $8000 on my lathe and tooling.
i had a us navy submarine lathe course 2week/then 1 week
i actually did some work in a marine repair shop
i am good at mechanical stuff
in 2015 i built a 6 dasher for 600/1000 yd br. as luck would have it, as i was finishing it the nationals came close by and i signed up. 4 day event. my first 600 yard match , day one i was just over mid pack at 600 , day 2 i shot a little faster, but as i was still working i had to leave as soon as shooting was over. ends up i tied a 3 target national record and won by a decent margin.
folks there is no way to put a price on the personal satisfaction of winning a national championship with a rifle you built yourself.
if you can afford it, and like mechanical stuff, give it a shot
