Gamo Magnums X 2

   So I've had a couple of weeks with the .22 and .25 Gamo Magnum Swarms.In 3 weeks I've put around 1500 pellets through them both.
Here's what I know about them after 58 years of shooting everything from .177 to 300RUM.
With the right glass, they're perfectly capable as a hunting/plinking rifle if you get the pellet right.
The .22 likes JSB Hades. 5 shot groups at 40m around the 3/4 inch mark, and I'm no air expert. 20m one hole 10 shot groups with the same ammo.
The .25 Likes JSB Exact Diabolo and is just about as accurate but very hold sensitive.  I've got Hades on order in .25 to see if that likes them too.
I've got a Sightmark Presidio 2.5 - 15 x50 on the .22 with an illuminated centre dot and parallax down to 10m and a Nikko Stirling 4.5 - 14 X 56 on the .25, also AO to 10m, both air rated.  The Presidio has some good quality glass and lovely fine etched cross hairs.  The glass on the NS is acceptable and the dots are a little thick, but that hasn't stopped it from performing.  Shot 2 groups in succession with that at 40m under 1 inch by a whisker earlier this evening.   That's sh*te for you target shooters but fine for small game where, if you miss the eye you still hit the brain.  Further out I'm aiming for chest shots and the .25 has plenty of punch for that.
You have to load them from the magazine with the same force every time.  As with all air weapons, seating the pellet properly counts and these are no different.  I think that may be where some people have the wrong impression about these Gamo Swarm Magnums.   The pellet loading and seating mechanism is very fussy.  Either you get it right or the flyers are legendarily off track.  Same full force every time is a necessity.  
More practice tomorrow, but that will be with the HW97.  I'll let you folks know what I think of that once I've  got it ranged out to the number recommended by Kruzaroad, 80m.  
Thats going to be an interesting challenge. I may end up swapping the Hawke on the HW97 with the Presidio, as the Presidio is way shorter and will make loading the pellet a whole lot easier.
