I absolutely agree with this and with what UncleNorby wrote. For all you know you might have mashed the trigger when you shot your second shot... and having dialed in rifles professionally (I know its retarded.... but for $50 plus ammo sales.... you'd do it too...) for several years.... you can pull shots on a lead sled.

Honestly, if it were me.... I'd get you a good set of sandbags and get away from the sled. I have seen more than one rifle damaged by them (one of them was mine... and it was a 7mm-08 too.... cracked the stock on my Encore). And while I didn't used to believe it... the gun needs the give of your shoulder in order to shoot correctly... and no matter how you slice it... unless you are carrying a lead sled with you hunting (have fun with that!) then you need to shoot it off your shoulder anyway.

I'd look at two other makes of ammo on very opposite ends of the spectrum. I'm honestly kinda suprised it didn't like the 140 PPs.... most guns will at least shoot them decently.... check out Fed Premium 140 Nosler Ballistic Tips.... I hate fed shotgun shells... but their rifle ammo is awesome. Also, give a try to some of the Hornady Light Mag 139s.... Innerloks or SSTs... your choice.

Good luck.
