I recently put together a .224 Valkyrie using a trued, stainless PTG left hand action with a fluted bolt and an M16 extractor with a Criterion 24 inch light varmint, 1-6.5 barrel. The rifle shoots lights out, the best group was yesterday, shooting FIVE rounds into yes--- .111 using an 80 grain Sierra HPBTM bullet and 27.1 grains of PP 2000 in Starline brass and a BR-4 primer.
I have a Rem 700 left hand 6.5 Creedmoor that I also built but the Creedmoor started life as a "plain old" standard action and the only mod was lapping the lugs and installing a Calvin Elite trigger.
ANYWAY, there is something that the new action does that the old one does not and that is the bolt handle will lift approximately one half inch (measured at the end of the extended bolt knob) when the rifle is fired. The "old" action does not do this.
I pulled the firing pins on both bolts and the "old" bolt uses the factory standard Remington fluted firing pin and the PTG firing pin is a solid, much heavier firing pin. I didn't ask for it in the build but the "solid" PTG firing pin costs 10 dollars more than a "standard" firing pin so I'm assuming they think it's an upgrade.
I swapped out the firing pin assemblies and the "old" firing pin in the new bolt BARELY cause hardly any bolt handle movement at all. The only difference between the two is the weight of the firing pin itself which is fairly substantial.
Why would it do that?
