Hello , I decided to make some serious shooting tests with my Ataman M2R Carbine in .22 , rear bolt action. I put a lot of pellets through it and the result is that this gun , mine anyway , is very pellet fussy . I shot H/N baracuda match , FX Hybrids , Predator Metalmag , H/N Sniper and Hunter Extreme , Superdome , H/N Field Target...none of these were grouping correctly. All were shot at about 860 Ft/s
The only pellets it shoots accurately , and very accurately, is JSB 18,13 gr , followed by JSB Hades 15,89gr. You're going to say that all I have to do is to stick with these pellets ; I just wonder if others owners got the same results , or maybe better ones with others pellets.
Another point I found out was the gun is also fussy about the moderator . I put one I did myself years ago , using a Weirhauch mod body in which I put conical shaped plasic caps from plastic bottles and aluminium spacers ; the bore , though , is quite large for .22 cal , about 10mm ...but it works for the gun . As I try to put some other moderators like Donnyfl , Huggett ( as used on all my guns ) , the groups open indecently ... can not understand why..
So guys , if you could give me some explanations or advices about this , you'll be welcome.
Ataman , anyway , are still great guns in my opinion.
