TC scout,dont short change your shooting ability to quickly.
Ive had to do a lot of testing to get my Mag barrel to that group.
Different OAL made a big difference especially since,both the Mag and max barrels have large 'leade" or throat distance from barrel to barrel.
Powder charge and brands made a difference too.
Even the crimp makes a difference. Ive experimented with light,medium and a factory roll crimp die that Lee sells.My best result concerning crimp was a slight taper but your results may vary.
Im not a hunter, but I used to be. Sorry to hear about your bad season.
Guess you dont want to hear about this 15 year old girl here in Rowan county that shot a 6 pt from her stand.
Then shot a 192 lb 7 pt with in minutes of the first one.
She made the newspaper here with that pic.
Guess hunting is like real estate,, location and location, that and a bit of luck.
