I look in on the Pyramydair blog occasionally.
Just had a quick look.....well worth a quickie visit.
There's a four part test on that new Diana AR8 rammer. Obviously full powered. Interesting read and the comments re the recoil are amusing. Trigger sounds good. Hold sensitivity.....
And an article on spring gun power adjustment. Mainly referring to how manufacturers may try and engineer apringers for different markets' power requirements. Maybe not a lot new for many of the more technically minded on here, but well worth a read. Especially the part about costs, testing, parts listings, inventory etc.
Oops - "Speinger" instead of "springer" in the thread title! Could you fix it, please, kind mods?
