Well, I finally got around to loading up.
I used the aforementioned Dillon, ADI 2205, Hornady dies and copper washed projectiles out of Rusa Leather in ChCh.
I made the cartridges up to the specs in the Lyman 49th ($25 US from Dillon Precision thank you NOT greedy NZ retailers!)
and this is what happened.
When I loaded a mag and tried the rounds for chambering, the very first round extracted and left the projectile in the lead, spraying powder everywhere as the case ejected!
It appears that the South African bullets have quite a different ogive to the originals (I am comparing to Norma, Federal, HMS and PMC which I had in my stash) and will require seating a lot deaper than the Lyman manual would suggest...
We had an M1 day at IMAS Bay of Plenty (Awakeri range) on Saturday and it was bloody excellent fun!
We shot 25 yd snap on pistol turners using reduced fig12 targets.
We then shot a 100yd trinity and then the 100yd 'Action M' and they all performed faultlessly.
I found that not having fired mine, the rear sight was not far enough left for me and I was hitting low and right. Three clicks across and a bit of manual elevation adjustment and voila! she was grouping about 6 inches or so (remember this is not benchrest, it's timed competition from prone, kneeling and offhand positions)
