started testing 250 SMK's over 91.0, 91.5 and 92.0 grs RL25 (from left to right, top three groups). Average velocities/extreme spread (FPS/ES) were 2692/38, 2708/34 and 2738/32. Three shots consistently went into less than 1/2 MOA, with two of the five opening up the group to around MOA. Not sure if it was the conditions, or the kit. Then I tested 250 Scenars over 91.0, 91.5 and 92.0 grs RL25 (from left to right, middle three groups). Average velocities/extreme spread (FPS/ES) were 2784/38, 2788/33 and 2823/22. Again, three shots typically went into less than 1/2 MOA (4 into 3/8" with the 92.0 grain load, two in the same hole), with the others opening up the group to just under MOA.
Magnífico, para un rifle de bajo coste.
En USA ya se le llama "el rifle de francotirador del hombre pobre". Unos 1.550 dóllares.
Yo le cambiaría el disparador por uno extremadamente ajustable (más al estilo 40X).
Y sobretodo, lo probaría con munición match comercial, Lapua .338 Scenar. Es un valor seguro.
