Re: Gun Builder's Accuracy Guarantee?
No problem, here is the brief explantion.
I mount one of our test scopes (mark 4 or NF) or the customers scope if they provided one. If its the customers scope, then I do a quick box test on a proven personal rifle.
Loads:
I have several "standard" loads that we use per caliber. They vary in bullets and powders. If a customer says they want to use a specific bullet, then I do the testing with that bullet, but will also test the other loads as well. I had a guy that just wanted to shoot Hornady TAP ammo in his 308. I purchased a couple boxes of it for testing and also tested the rifle with the standard 175SMK load as well. What I have found is, because the rifles are all chambered with the same reamer, my standard loads are pretty consistent barrel to barrel. Sometimes a little tweaking may be needed, but its rare.
Range testing:
All testing is done under field conditions. I shoot prone off a bipod and feed from the magazine. This allows me to check the function of the rifle and how it is going to behave under field conditions. I shoot 4 test targets at 100yds to start with. 5 shot groups for the smaller calibers, 3 shot groups for the big boomers. This gives me some idea of consistency. Then I move out to 500yds and 950yds. Again, a few shots to check consistency. Generally I have 30-35 rounds down the tube when I am finished, sometimes slightly less.
Once this is all complete, I clean the rifle, enclose test target, load data, and a dummy round. The remaining targets go in the customers file with the build data.
I know there are alot of reputable smiths that don't test and their rifles are very accurate. I just prefer to test them before shipping them out. This is just our process is all. I am just a "small fish" smith in the big pond. I just figure if a guy has waited 4-6 months for the rifle, he is wanting to shoot the damn thing. Not mess around with load workup, etc... I know that part of the fun, I just speed the process up a little is all. Most guys actually just stick with the standard load I provide and call it good.
Hopefully this answered some of the questions. There is more detail in it than this, but it at least gives a little idea of our process.
