Leshiy 2 350mm .22 and Slug

The FX slugs slide right out the magazine . They are .216” . I tried some NSA .217 and they stayed put but just barely. I have ordered some .218” which I think will be the ticket. Don’t know what the barrel measures out at as that is very important too. You could still load the .216 and .217 slugs in the magazine from the front like you do on the Umerax A6 . The steel magazine clip would keep the slugs from falling out the back. Then once the magazine is in the action the slugs can’t fall out. Just because they are somewhat loose doesn’t mean they won’t be accurate. My Umerax K500 Huntmaster is very accurate with any slug and most pellets I put in it and they are very loose fitting by design because you have to load them from the front so don’t think the ammo has to fit the cylinders exactly to be accurate. As long as the cylinders index with the barrel And most important the ammo is sized properly to the bore the ammo will center itself with the bore . It has no other way to fit. I haven’t increased my reg pressure yet which will be required to push slugs fast enough so I haven’t tried shooting them. Still waiting on Ed to make the video on tuning the Leshiy 2. I can’t help with the .25 but I do have the .30 barrel kit and the NSA .300” slugs fit snug in the cylinder. I haven’t tried them either because I’m waiting on Ed to make the video on how to tune the Leshiy 2 . Oh did I say that already 


 
From pure theory point of view the projectile is pushed while in magazine and engages the rifling as it moves forward. Pellets have 2 contact points at opposite end of the projectile so fairly easy to get straighten out if pushed a little side ways. With slugs there is only 1 contact area/point so if it is not engaging the rifling dead straight it will be harder to correct. 


if anything try the longest(long contact area to help straight the projectile out) and the biggest diameter so the slugs won’t be loose in the mag which causes the project tile to not engage the rifling dead straight. 


This design simply won’t work well with slugs consistently IMHO. If you want to shoot slugs then a gun where the slugs are seated consistently with a probe would work better. In semi auto realm the AEA’s semi auto system which uses a reciprocating probe is the better design and that gun is known to shoot NSA slugs well. 
 
I've done some testing with .22 slugs, but most of it was for naught. I was testing some NSA slugs in my Cricket II and decided to give them a shot in the Leshiy 2. I had known from previous shooting that they were all pretty bad in the 875-950 fps range. The Leshiy 2 was setup for JSB 18.1 in the 860-870 fps range. I had the NSA 17.5 gr and 20.2gr, both in 0.2165". Loaded them up and it was shooting the NSA 17.5gr right around 825 - and the grouping was tight. I shot the 17.5 a lot more and was impressed. Re-configured the L2 to shoot the 20.2gr right around 825 and again accuracy was spot on. 

I've taken both 0.2165 17.5gr and 20.2gr slugs out to just under 50 yards in my back yard and they're both giving under 1" to sometimes 1/2" groups. They handle my swirly windy back yard much better than pellets. 

EDIT - I wanted to note I've lapped my .22/350 barrel twice with JB bore paste to get the accuracy I am getting. OOTB the barrel was shooting a bit of a spread.

I do get the one odd flier per mag which I've attributed to what others have mentioned already. Even though the feeding from the mag into the barrel is generally very smooth, I'm sure it doesn't take much for a poor feed to cause a flier.

Now regarding the slugs falling through the magazine. You gotta get a speedloader and just keep the magazine in the gun. You simply remove the backplate, position the speedloader and let the slugs fall into the slots.

I have been playing with the nsa 20.2 grain .218 slugs and have been the best results out of all slugs I’ve tried. I got 7 in one hole basically twice and both had a ow right flyer. I did not change reg pressure yet and I think they were shooting around 800fps. Yes they still fall thru mag bit I use a speed loader that last plenty on a 300cc bottle and just fill mag on gun with no problems so far.
