I decided to buy a Rainstorm to test out. I had bought and sold a Marauder, unfired, because the ergonomics and weight of it were not to my tastes. I am 5'7" and hunt in the mountains so lighter weight guns with good balance fill my stable. Almost every airgun I have bought new from $50 to $1500 had problems out of the box that needed attention and the Evanix was no exception. I like the weight, balance, and fit of the stock. The finish and grain were very good. Part of what makes this stock feel so good is a very thin wrist. Don't drop this gun!
The 10 round magazines (you get two)are robust and metal, but pellets fall out, or slide and jam the mag rotation. The magazines had a milled slot for an oring, but no oring. When I fitted an oring it did not reach the pellets. I took a Dremel with cut off disc and opened up the slots only over the chambers so that an oring would slightly protrude into the chambers ala FX magazines. Then I debured and lightly pollished the holes inside. Problem solved.
The gun is well made, fully shrouded, and quiet for the power range. The side lever works very easy and smooth. But disassembly showed easy improvements. Disassembly (before firing) revealed pellet clipping, from factory test firing I presume? I drilled out the baffles before firing my first shot. The front barrel bushing was poorly vented. Talon owners will identify with heavily venting the bushing as I did on this Rainstorm. I also stuffed green Scotchbrite pads into the rear of the shroud. Now the gun is very quiet with ping causing most of the noise. A depinger will be the next modification.
A full fill to 200 bar using Kodiak .22- 21.5 gr pellets showed velocities starting at 959 fps constantly descending to 888 fps by the 15th shot-typical Korean shot string. The hammer spring is adjustable, but full out still was on the back side of the curve. I swapped out hammer springs and with a couple adjustments got a bell curve of 30 shots with an ES of 50 FPS peaking at 905 fps or 39 FPE. Top of the curve gave 2 magazines (20 shots)with 30 fps ES. Good, not great, but typical for this power range. Accuracy was very good for a hunting rifle. The following photos show the first 10 shot group with Kodiaks at 50 yards, no wind flags and using a cheap 4X scope with no AO.
As with most of my 10 shot groups seems I let one fly, but that is real world shooting. Note no aim point as this was the first 10 shots it was several inches high. After zeroing I was pleased with the accuracy.
The two stage adjustable trigger pull after a light stoning and lube is right at 2 lbs and is crisp. I expect it to get a little better with use. The safety is recessed into the stock making it awkward to access, especially if one had gloves on.
So for a couple hours tinkering, a hammer spring, 2 orings, and a scotchbrite pad I got a very good hunting rifle.
PA had some used Rainstorms at a nice discount. I decided to buy a new one using the 10% off code. After seeing the pellets fall out of the magazines and pellet clipping the baffle I can guess why PA had the returns on their shelf.
I am pondering adding a regulator to this gun. Has anyone done that yet? I would like to hear from you if you did.
