Re: info on building a 700 Remington 7mm into a 1000 yd gun
Matt,
It really depends on your goals and accuracy requirements. If you're happy in the 600 yard neighborhood or one minute of angle (at long range), you can do a lot without truing. For utmost precision, it's a key component.
My shooting evolved like many others. I started with factory rifles, started improving them myself, soon all my rifles were semi-customs. It didn't take long to want more accuracy, more consistency, more reach. I have seen the limits of each type of build with many rifles.
Long range is about precision. There are stages. 300-600 yards is the simple stage. 1000 yards requires a lot more precision, better rifles, and good loads. Beyond 1000, things really start to show.
For me, long range hardly starts until 1000. My rifles are full customs, trued actions, or custom actions, with superb barrels, stocks and triggers. 1/2 minute accuracy is a minimum expectation. 1/4 - 1/3 minute is typical. At long range, I have a system.
My rifle is as accurate as it can be. My ammo is tuned to the rifle, to shoot tight groups with minimum velocity spreads. My scopes are tested. My trajectories validated. I use rock solid rests, and hone my shooting techniques, and doping skills constantly. The result is awesomely accurate systems.
You can play the game at any level. Progressing through each phase, as I did, is probably very beneficial, and educational. I wholeheartedly endorse action truing. But, it's part of a full custom. I would not true an action without screwing a custom barrel on it. Nor would I screw a custom barrel on a factory action without truing. I have built several semi-customs that were superbly accurate. That said, the difference between a tuned semi-custom and a tuned full custom is usually dramatic at every step.
