    I've done a fair bit of work to my Lelya to get it customized the way that I need it to be. A big part of that effort has been focussed on the barrel, where my objectives were to eliminate all flyers induced from leading, and have it provide laser beam accuracy with a select handful of heavier projectiles. 

    During the tuning process, I learned that there is a real fine line with the barrel's tension (via the 12mm barrel nut), which makes all of the difference with accuracy.

    So today, I drove out to the mountains to test some changes that I made to my Lelya. I had the regulator set pretty low for optimizing shot  count with the JSB Monster RDs at 836FPS. My spread is 1 with this tune for all but the first 3 last two (40) shots in a 290bar fill. The FX Hybrids were shooting at 830FPS and I was only getting the 24.8's out at 780FPS. The fog was THICK today. I could only see the targets clearly at 68 meters. These are 10 shot groups (my NF 1-8 scopes have parallax fixed at 125M).

    Excuse the messy targets – I forgot to pack splatter targets today, so I had to get creative with the targets on my carboard from a previous zeroing session lol

    JSB Monster RDs


    NSA 24.8's:


    I shot these off of my bipod and padded shooting mat, no rear bag – the Lelya is very stable and well balanced with just the bipod positioned where it is. I think the FX Hybrids have an edge over the other two in my short barrel. My new Taipan shot them well today too, but the Monsters were just ferocious with the Vet!

    In any case, I'm very happy that I have numerous options for ammo with that guy. The more the merrier! 🎅

    A couple of things to add:

    • My POI on the top two were the centers of the neon crosses, and the bottom was the corner of the outer bullseye diamond
    • This would be the third choked LW barrel now that I have used with all three projectiles, so they're all compatible in my book

    Very nice groups.  I think I'd heard something similar about the R5M barrel lug.  

    Doesnt the 125yrd parallax  make grouping at shorter ranges trickier?  I imagine it would depend on the scope in part, but I honestly don't know.

    Yes, it can definitely throw POI off … ever so slightly.

    When you're behind the optic aiming at targets that are closer than the fixed parallax distances, if you move your head a little in a circular motion, you can see the center dot move a little (I'll measure it next time I'm out) – just as you would with a variable focus optic that wasn't focussed properly.

    In terms of precision shot placement, I work through this issue by making sure that my optics are setup in a way, where I do not have to "fight" against the unfocussed parallax. I just have little tricks that I use with my cheek rest, where it feels uncomfortable or unnatural to plant my face somewhere that's outside of the proper point of aim. Hard to explain, but that's what I do.

    I wouldn't want to use them as full-time BR scopes for close target shooting. You can totally do it, but you wind up spending a little more time validating POA than you would with an adjustable scope.
