So I acquired a 1941 Finn Mosin ..after about 4 hours of rigorist cleaning.. Bore slugs 309 ..
trigger at this point is horrible (to be fixed later)
I have a NOE 311-247 HP Flat base mold I have been working with my 300 Blackout.. Have had real good luck finding a Subsonic and a 1450 FPS load for.. Bullets are powdercoated Jet Black
Thought what the heck I should try it in this Mosin
12 grns of Unique gets me 1373 FPS Average and a SD of 5.1
50/50/2 Alloy
Group size of 1.25".. 100 yds open sights.. old eyes and very bad trigger
shot 3 more 5 shot groups before I called it good enough to invest time to do a good trigger job and some tweeking to the load..
Sometimes you just luck into a good load from the start
