Didn't really have a favorite till three weeks ago.
Back in 2003 I bought an as new condition M-48 Mauser from Big 5. I took it to the range one time shooting old surplus Turkish ammo. Accuracy was about 4" to 6" at 100yrds open sights. I was a bit dissapointed in the rifle and it has been a safe queen since. I had bought a box of Sellier & Bellot 8mm back then, but never shot any of it. Three weeks ago I bought a real nice Tula 91/30 Mosin Nagant and as I was walking out to goto the range to test fire it, I thought I would bring the Mauser and that box of S&B ammo.
All I can say is wow. I had three sub 2" 5 shot groups and one 3" 5 shot group with it open sights at 100yrds. Getting away from milsurp ammo and using good quality ammo was the trick.
This m-48 Yugo Mauser is my go-to rifle for hunting and anything else now. I am about to drop a dime on reloading for 8mm for it also.
I'm keeping her stock military and open sights.
