Parker Sage's,

I have plowed through numerous threads on this subject, and am still unable to ferret out the exact info I seek. I just got the letter on my "new to me" 12 ga, 30" DH. It states that the gun was special ordered to target RH325 pellets and LH 350 pellets using 1 1/8's oz of "shot" (size not specified) in a 30" circle at 40 yards.

Am I right, that, if using #7 shot that the gun is regulated for like 90% and 97%? That seems like crazy tight. This might be a different story if the gun were regulated with #9 shot...but that seems unlikely.

I guess I'm still a classic double hayseed....I miss plain words like Modified, Improved Cylinder and Full!

Any light to shed?

Thanks to all in advance...
