Things I liked:Arrived with-in days of ordering. When fired with a Crossman Air Gun, competition scores increased 30 points! Works good with Avanti/Daisey CO2 800 series, provided you're an experienced shooter. Things I would have changed:Offer a 500-1000 can product. What others should know:Would not these pelets with inexperienced or first year 800 series CO2 Air Shooter. Again, with the Crossman air gun, Diablo's increased competition scores 30 points! I have been coaching air rifle competition teams for 5 years, and my current team has a college rifle letter of intent signee, and 10 other shooters that are being watched as underclassmen!
