I received my Mora .25 Standard from Tony a few days ago. Had my first chance to take it out to the range today. Needless to say I am still learning the platform so tuning is still a work in progress.
When I bought this I had all intents to shoot the .25 Altaros King 66gr. Before todays outing I upped the reg to 175 bar and had it shooting what I thought was 895fps but came to find out was closer to 870-880 fps (apparently my v1 FX Chrony is reading about 15 fps high). I was nailing some really good groups and some not so great ones. Tried to up the speed a bit but found out I ran out of valve adjustment travel. I think I was just blowing too much air for really consistent shooting.
When I got home I tuned the reg up to 190 bar and brought the valve in more than half way. Some minor adjustments and I was shooting 890-895fps for real with the Kings. I could tell from air usage that this tune is more efficient, but it still uses a lot of air to get almost 120fpe out of a .25 airgun.
In terms of some comments about loudness - at 120fpe it is not a quiet airgun. With just the shroud it's got some bite. With the added moderator it helps but there is no way it is suburban backyard friendly IMO.
This is a big heavy rifle. Definitely a bench gun. The trigger is very nice. Very light first stage and a clean 2nd stage break.
I found getting a good view through the scope was a bit of a challenge, but it could be do to too low rings and the Mora's cheek rest being delayed. Also, no manual out so there are some adjustments I am leaving alone until I know better what they do (ie: trigger settings)
Overall - initial impressions are very good. This is my first RTI airgun. I was skeptical about being a Mora v1 guinea pig but it seems they've gotten most things right.
Edit - ok, I do have one complaint. The Mlok handguard on the bottle is a bit flimsy. Whether using a tripod or a front bipod setup there was more flex than I would like. I hope K&L step up and make a more rigid Arca rail.
