Too windy today to post groups but I had to shoot it to see how it sounds and get some velocities in .22 and .30 calibers. My first impression of the gun is its impressive how much power can be had out of this little gun. It’s literally a pistol with a stock attached. Not a super light weight but heavy enough to hold steady offhand. You definitely need to get a high strength rare earth magnet and glue it to something to carry with you to take the black cylinder plate off the back of the red cylinders. I made my own with a magnet cemented between two pieces of leather with a lanyard to hang around my neck. It will be interesting what others come up with. A potential problem came up regarding the cylinders while working on my gun on my garage workshop table. The cylinders have a strong magnet within them and so they attract any little piece of steel metal. My table had tiny shards of steel from filing and grinding that I had not cleaned up well and before long my cylinders were covered looking fuzzy. They were not easy to clean so be careful where you place your cylinders and check them regularly . Even the magnet you will use to remove the cylinder cover will attract metal shards and can transfer them to the cylinder and cover. Now I have the gun I see there is no clearance to add any material to the outside edge of the cover so that isn’t an option. I’m going to try filling one of the cylinder protrusions at an angle to give a little relief to get a finger nail under the cover. My cylinders do not have numbers on them so that will be my #1 when loading and I can see when I’m about out of ammo. My gun came as a 350mm in .22 so I assume the regulator is set at 130 bar. I shot JSB jumbo Monsters RD 25.39 gr. At a velocity of 783 to 788 FPS. I then shot Predator Poly Mags 16 gr and got 883 to 890 FPS . Last I shot JSB Hades 16 gr and got 889 to 897 FPS. I then put my .30 caliber 450mm barrel on which is so easy and quick. I was never a fan of multi barrel guns but this one is a snap to change . I can see why Ed added the split ring to the breech end of the barrel as it gives you a positive stop but that means you have to remove the moderator every time you change a barrel to pull it out the rear of the action. With out the ring you can just pull the whole assembly out the front and leave the moderator on the barrel and insert a different set up from the front saving a lot of time . It is no problem to just close the action with a cylinder in place and when the barrel touches the cylinder you tighten the lock screws and it is set. You still have to make sure the barrel is just touching the cylinder when you have the split ring on the barrel. If Brian reads this maybe he can let us know if there is any harm in inserting the barrel from the front without the split ring. I then shot the JSB 44.75 gr and got 618 to 621 FPS. Obviously the regulator needs adjusted up for the .30 caliber but the instructions do not show how to do this and I’m not going to get into tearing down the gun until I see a video from Ed or ‘Brian . I’m hoping I can set the regulator at 160 for the .30 and then drill out the extra Puck to tune it down for the .22 to shoot what it likes best. I talked to Brian today and he is working on more videos for us so be patient . I ordered the ShoPot forearm and moderator for both the 350mm and 450mm barrels. I can tell you the standard moderator on the 350mm in .22 is very quiet with reg on 130 bar. The ShoPot set up have more of a Pop to them so I wouldn’t call them back yard friendly. I shot the gun without the moderator and it cracked like a .22lr! So the moderators are Still working well. Perhaps some one can tell us how well the other larger Valkyrie moderators work. Be sure to clean out your barrels before you start shooting. They are coated with machine oil. I’ll post more on accuracy once I get the barrels worn in and the wind isn’t an issue.
