I purchased a Benjamin Prowler years ago but it shot so poorly with OTC pellets from the box stores that I closeted it for several years thinking I would find some miracle fix online someday and resurrect it from the closet once more. My wife bought a Diana and some JSB Exact Jumbo's so after a good scrubbing and a polishing with Flitz, I loaded up and shot a string of 6 shots at 30m and after the fouling shot, I ended up with a 5 shot, 12mm group! Amazing success! I tried the box store pellets again and found them to still be minute of cantaloupe accuracy at 30m so JSB it is from now on!
Things I would have changed:Gosh... give them away? The cost is fine, 4 tins delivered with shipping for $60.00 is amazing!
What others should know:These seem to have a light film of lubricant on them and the skirt in my batch measured .225" on average and the head measured .218" on average. This was an almost exact match to my lands of .2182" after measuring the bore slug.

What is the normal percentage of bad pellets per tin? I had to throw away about 20% of the pellets because of damaged skirts.
Will these be too heavy for gamo swarm maxxim .22? I've been shooting 14.33gr before.
No. They should shoot pretty well.
I'm about to order the Sig ASP20 22CAL. My plans were to order this pellet or the 18.13 Hoping some of the ASP20 owners would help me make a decision on which. Thanks for any suggestions.
You really need to try a few different .22 pellets. There is enough variation in tolerances between barrel and pellets to warrant trying different pellets before settling on what your rifle will like most.
