Reliable, very accurate multishot
Moderate weight and good fit
High cost of accessories especially magazines
The need to buy tanks, pumps, quality scopes
and mounts. If you elect to use a tank you have to find someone to fill it.
I’ve had my 410e for about a year now and I’ve shot perhaps 5000 pellets through it. It just keeps getting better and better. Right now I’m averaging .310 inch error over 25 shots at 38 yards and I expect that to improve as I get a quality bench and bench rest. I like the ability to improve my accuracy with more attention to detail.
The gun has the Pomona power mod but I am so pleased with the chrony results that I haven’t touched it.
I’ve done extensive pressure fill testing using JSB .177 4.52mm 8.4gr pellets with the following results:
3000psi fill yields 76 shots at 1017fps +/-32 fps
2900psi fill yields 46 shots at 1024fps +/-16 fps
2800psi fill yields 38 shots at 1026fps +/-13 fps
2700psi fill yields 22 shots at 1030fps +/- 4 fps
With the current accuracy I’m deadly to rodents (I have a pest problem) between 18 and 50 yards.
I’ve had no magazine problems (I have 5); baffle blowout, o-ring blowout or any other problems.
Before I bought a CF tank I made sure that I had someone lined up to fill it to 4500 psi. With the 88cu ft tank that yields about 46 airgun fills to 2900psi and 50 shots per fill.
