Wayno and mcb66, do you both have the newer, 58x series Mini-30s? I've heard that the 58x series shoot the Russkie ammo more accurately with their thicker barrels (much like my 583 series Ranch Rifle does) and that all 58x series Minis have a stronger firing pin and that coupled with a Wolff hammer spring, eliminates many of the issues with light strikes with the Russkie ammo. Can you confirm this? What specific brands of ammo do you shoot through yours?
Yes, both of my Mini-30's are 582xxx series. Again, the first one will fire any steel-cased ammo. The second one will not. It has a 20% fail-to-fire with berdan-primed ammo. Accuracy has never been an issue in either one, regardless of any steel-cased ammo, in fact I will say the accuracy is quite good with any ammo. Which brands of steel-cased ammo? Wolf, Herters, Tulammo, Silver Bear, Golden Tiger. When my Mini-30 fails to fire, it does dent the primer with what would seem plenty of authority, but still not enough to ignite the hard primer. On the second try it does fire. It fires any and all boxer-primed ammo with no failures of any kind.
I've not changed the mainspring and I do not intend to. As hard as it does dent boxer-primers, I do not want to increase the hammer force and risk puncturing the softer primers.
For the record, I've also shot steel-cased ammo with my Mini-14, and I've never had a fail-to-fire issue.
And as I've said previously, my intent is not to shoot steel-cased ammo exclusively, but I do need to know if my guns will handle it if it's the only ammo that might be available.
WAYNO.
P.S.
I just visited the Golden Tiger website. On their cover page it says this. Duh. :lol:
"NOTE: 5.45x39mm & 7.62x39mm caliber firearms may require a heavier Hammer Spring for ideal performance
and reliability while using Golden Tiger Ammunition in these two calibers.
Please see your firearms manufacturer or distributor for details."
