Andy,
Sorry if I missed this, but what is the power source for the fridge?

Gun Dog,
I shoot rather large quantities of Wolf Classic and Black Box (polymer coated / steel case 223) and have never had a problem. I'm curious to see how your Gold performs, because I have a piston AR that doesn't like Wolf Steel Case. I need to try a Carbine buffer in it before I start spending extra cash on brass case ammo (currently has a H2 buffer).

I've probably shot in excess of 10,000 rounds of polymer coated / steel case Wolf and outside of: A) being very dirty; B) being on the weak side; C) providing 2-3 MOA accuracy its great training ammo. I often chide "steel case haters" who spout off the standard "would you put 89 octane in a Ferrari" line. The fact is, Wolf steel case will pay for itself very quickly:

SHIPPING COSTS OMITTED

Wolf Steel Case / Polymer Coated 55gr = $225/1000
PRVI Brass Case 55gr = $320/1000
Federal 193 = $400/1000

Using the cheap brass case as a comparison:

BCM MidLength Upper with Charging Handle & Bolt Carrier = $585

Cost Difference B/T Steel & Cheap Brass = $95/1000

$585 / $95 = 6.16 Cases

Every 6.2 cases of steel case ammo funds a whole new upper.

Brass Case For Training = Fools Gold
