How well does the Mini 14 handle Wolf ammo?
I have shot tens of thousands of rounds of Wolf through several Mini-14's and Ranch Rifles.
My ranch rifle used to do fine with it until I changed to a smaller gas port bushing. Now Wolf ammo doesn't want to cycle the action.
Most minis will shoot Wolf with no problems, I reload and collect brass but if I was in a pinch it seams its an easy find.
Good question. The answer is Yes, Maybe.
It is said that Berdan primed ammo is hard on the Mini's firing pin and can cause it to fail. The Wolf I have seen in Berdan primed
It is said that Berdan primers need a harder hit than Boxer primed ammo. This may require a Wolf hammer spring for increased reliability.
It is also said that Wolf and other Berdan primed ammo will work just fine in the Mini.
Ruger does not recommend the use of Steel cased Berdan primed ammo in their firearms.
The hard primers are due to materials used to make the primer cups. Has nothing to so with berdan, or boxer. The places that use berdan ammo generally use it for military ammo, and use the harder primer cups to reduce the chance of firing when the floating firing pin (which many semi autos have) hits the primer. Many companies make hard and soft primers.
Since the mini has a floating firing pin I would suggest using hard primers. If a hard primer causes any damage to your firing pin, then there was some serious production issues at ruger, I have never seen a firing pin damaged by primers.
The mini firing pin is not a true free floating pin as in an AR. The tail or key keeps the firing pin away from the primer until the trigger is pulled. Do a test for yourself, chamber a live round then slam the action closed hard. Remove the round and inspect for primer dent, you will not find one.
Only the Wolf Military Classic and the 75 grain WOLF Polyformance is Berdan primed.
Correction, The key/tail keeps the firing pin off the primer until the bolt completely rotates into it's locked position. Slam fires are not possible with a Mini in proper working condition.
