TT,
Your conclusion regarding the accuracy of the gun based on one load at 20 yards is useless.
You base your entire assessment of the gun's accuracy on ONE load.
You have no clue.
Try TWO guns, with MULTIPLE loads, at 25 yards, off a solid rest, and then I'll grant you credibility.
In the meantime, having done that & found both guns to be wildly variable with ACP loads, I give you none.
The guns CAN shoot decently with ACPs, but you may have to experiment to find a load that does.
You apparently stumbled across one your gun shoots well early on.
In no way is that an adequate evaluation of the model's capabilities, and in no way does it support your broad advice to disregard "claims of inaccuracy" by those who do have a basis for making qualified conclusions.
When I was getting 25-yard groups of 5, 8, and 13 inches as BEST groups in 8 different loads through both guns, my fact-based impressions of ACP accuracy differ greatly from your extremely limited experience.
