Scope dope — I hope! Part 4

Part 3

This is an ongoing series about scope questions and issues. Blog reader David Enoch asked for it originally, but many other readers have jumped in since it began. Today, I’ll talk about adjustable scope mounts.

First things first
Why do we need adjustable scope mounts? Aren’t the scopes, themselves, supposed to adjust? Yes, they are, but 2 things quickly become a problem. First, the scopes don’t adjust as far as we need them to; and second, when a scope adjusts toward its upper and right limits, it loses its precision. I will address the second problem because it’s really the principal one.

Today’s report is an important one, but it may be confusing until you hear the whole story. The last time I reported on this Tech Force M12 combo was back on November 19 of last year. A lot has happened with this rifle since then, and I’ve kept daily readers informed of what’s been going on, but it would have been easy to overlook and even easier to forget. So I’ll summarize.

The M12 I’m testing is a drooper, and I first had to solve that problem. Once I did, I noticed it threw fliers. I cleaned the barrel — but it got no better. I tightened all the screws — again, no change. I cleaned the barrel with JB Non-Embedding Bore Cleaning Compound — and still there was no improvement. Then, I shot the gun just to break it in — again, no change.

I usually have a handle on the gun by the time Part 4 rolls around. But, today, I’m still stymied by the Tech Force M12 breakbarrel. I’ll tell you all I’ve done to make sure this rifle is on the beam; but when I tell you my results, I think you’ll see I’m not there yet.

Big droop!
I discovered in Part 3 that the M12 I’m testing is a big drooper. That means it shoots very low relative to where the scope is looking. For today’s test, I installed a B-Square adjustable scope mount that has a huge downward angle to bring the point of impact back up to the aim point. It worked well enough for the test, so I proceeded to shoot several different types of pellets — trying all kinds of hand holds and even resting the rifle directly on the sandbag.
