Here's my review of the Simmons Master Series ProHunter 3-9X40:
First order of business was to focus the scope. It has a small rubber ring on the ocular to turn for focusing. The first time I tried to turn it, the ring came off, so I left it off while focusing the scope. Not a good start, but a little rubber cement should fix that. Now I was faced with a decision - did I want the target (at 100 yards) in focus, or the reticle? Seems I couldn't have both, so I chose the middle route, leaning toward the target. I got it satisfactorily focused. Hmmn!
I did my initial sighting-in with Remington 140gr CoreLocts. After a couple of foulers, I moved the bullet strikes to 2" high, then fired a 3-shot group of about 3/4" The clicks were right on for distance and direction, and did not move with repeated firing. Better.
I cleaned the bore, changed the target, and switched to Hornady 140gr SSTs. Elevation was still 2" high, but was 1" to the left of the Rem ammo. I cleaned the bore again, fired 2 foulers, then a 1-1/8" group in a gusting wind. Good enough for deer hunting.
Bottom line: The ProHunter is not the best thing since sliced bread, but for $120, it will do.
