I confess...I goofed up, I just hope not too badly.
I have a couple of rifles that are fairly new and I haven't yet completed the full break-in routine on them. The problem is that the other day I forgot that my Mini-14 SS Ranch was one of them. I had been using a 3 shot/clean schedule on it and only had about 6 shots through it. My buddy stopped by the other day to shoot a little and I grabbed my Mini and we put two 20 roound mags through it, using 62 gr. FMJ Russian ammo (not Wolf).
How much "damage" do you think I did at this point, and is should I restart the break-in schedule or have I gone to far already to make it worth the effort?
In fact, I own one myself and use it for 95% of my hunting in the US with the exception of moose, bear, and varmints. At last count, it had 42 deer, 7 elk, 4 wild boar, 2 dall sheep, and countless coyotes to its credit.
I think you will be pleased with the results a bedding job and free-floated barrel will give on a Rem 700. In fact, I trust that you will see immediate improvement in average group size. Mine, which has only minor modifications... a bedded action, free-floated barrel, and a lightened trigger...will drill out sub-MOA groups at 200M all day long with handloads, and it will do near that with off-the-shelf Hornaday Light Mags in the 140gr flavor.
Also... don't worry about the guinea pig syndrome on the 700. After all, there is a wealth of information on effective modifications for this rifle. I guarantee you...if you can think of it, it has probably already been done to a 700.
Besides...guinea pig syndrome affects us all. And it always passes when you lay out a sub-MOA group or two.
