I've taken my Turk 88/38 to three good smiths and all three suggest, highly, not to shoot it.
It seems the Turks were poor metal workers and, in my case as with many, the mauser's receiver, barrel and bolt strength is very poor. And it seems their quality was hit and miss....in that, some gun metal had high tinsel strength while other gun metal was near pot metal quality.
I'm not sure who can, or how one could, improve the metal quality in order to safely shoot it. In fact, without changing out the complete barrel, receiver and bolt I see no viable and inexpensive way to convert mine to a shooter. So, I'm out over $100....kinda expensive for a collection of parts. But, dang, it sure looks good and is pristene otherwise.
I checked back with the gun store to see if they would trade it back in toward another gun buy and they just laughed (probably like they did when I walked out with it). That was one valuable and educational learning experience.
I'd be VERY careful when even considering a Turk and I would only consider buying one unless the seller is a qualified smith who blesses the gun as sound or someone who allows you to take it to a good smith to be checked out. In other words a Turk is certainly one gun I would NOT buy sight unseen and outta magazines such as Shotgun News.
I've heard stories that the Germans sold some of their mausers to Turkey so if you find one of those I would suspect the quality would be high enough to consider it as a shooter. But watch out for true Turkish made mausers.
After replacing the sights on my two Swede 96s so they zero in at 100 yards I'd have to rank them as El Primo! They shoot as accurately, if not slightly more accurate, than my American Springfield/Remington 1903/A3.
My Yugo M48 is ranked second.
Keep in mind that many, many mausers were manufactured to be accurate at 300 yards so if you do buy one don't panic if it shoots high at distances our ranges are at normally (100-150 yards). But there is always Brownells to buy a good and inexpensive front sight blade that can be filed down for 100 yard ranges.
As pointed out by Big Dog the 8MM is no whimpy caliber and it's very very close to a 30.06 round......large and powerful enough for most North American game....a tad light for elephants unless it's a straight on head shot, lol. The only problem is the majority of surplus or foreign 8MM is corrosive. Sellier and Bellot sells it non-corrosive but it's slightly more expensive than surplus.
