More thoughts and new information:
MSC/MASA that's Maribel Airgun Shooters Association, will have an outdoor Field Target event this Saturday Aug 5th. Gate opens at 9 for sight in, 10:15 safety meeting , 10:30 match. Likewise come Oct 7th that will be our second match. Any airgun as long as it can shoot a pellet at least 750 fps. That's to be able to knock the targets at plus 45 yards. We pretty much stick to .177 or .22 calibers, but that's not a rule. Questions email the rifle range, see web site.
Thoughts: in prior discussion I talked about equipment and the costs. Don't get intimidated by those $ figures. Any affordably priced gun will do the job. Piston guns are common in the retail stores. Benjamin, Beeman are known performers. PCP guns from Benjamin and Gamo have low cost model that can easily be hand pumped. The real issue become range finding the targets in the field. Thus you need a scope that is AO adjustable on the bell or has a side wheel adjuster. With these devises you can dial in the target range to calculate pellet impact. As a rule you will need a scope that ranges down to 10 yards because that's the closest target on most courses. If you will shoot hunter class you need only a scope that goes to 12X. You can have more power but you can not use more in hunter. In the other classes power unto 50X are common. A good cross over scope would be in the 8x32-50mm range with side wheel. Common scope brands are Crosspoint, Utg, Leaper, Vortex (when on sale) in the under $200 range. Go to the online airgun retailer for best selection. (Pyramid Air, Airgun depot, Arizona Airgun etc.)
If cost is the biggest factor get a piston rifle. I would suggest the Benjamin Trial NP with leapers 4x12-44 side wheel scope. That should cost around $300. If you like the PCP concept I suggest the Benjamin Discovery with the same Leapers scope for about $450. What ever you decide to get, choose .177 caliber. Reason (example) you have .25 cal rifle (1/4 in) and must shoot thru a (3/8 in) target hole (common) not much room for error. One note if you decide on the piston gun you will need to learn the artillery hold (google) to get it to shoot consistently at all distances.
Come out and shoot with us, we don't bite.
