Got the Yugo Mauser out this weekend and did a little plinking with it. Walking through the woods and sniped at random rocks, pine cones and chunks o' wood. What a blast! I keep forgetting how accurate this combination is. Range doesn't seem to matter, 50 yards to as far as I can see.
This combination does not seem to be sensitive to load, powder or anything else. It just shoots. I've loaded up 5744, Varget, IMR4895 and H4895, various seating lengths and a couple of different alloy hardness's. I use Lyman #2 or a little harder as a rule. Pretty much the same results with all of the combinations tried so far. Bang, smack, grin.
I did try sizing these down and paper patching, with essentially the same results. Bang, smack, grin. More time consuming to produce for the same results though, so I stopped doing that, mostly.
These are shot at a velocity of right about 2,200 - 2,300 fps, and regulate with the military sights pretty well.
The Saeco is a gas checked design, with one large grease groove. It weighs in at about 195+ a little grns with my alloy and checked / lubed. I seat them so that the gas check is right at the base of the neck, which puts the crimp groove about a 1/16th of an inch out of the case and the bore riding nose into the lands a bit. No crimp and neck sized only. You do have to be a little careful as any more COL and you can start pulling bullets if you extract an unfired round.
Gotta love it when a plan comes together!
