Glockky IMO it all depends on exactly how your chamber was reamed.
Only way to be totally sure is to do a chamber cast or a pound cast.
With a Handi Rifle both are pretty straightforward.
I am using the .360dw brass for my best loads, including some of the lee 200 grain. Mine are not set quite that long. All depends on exactly where the ogive kisses the rifling.
I am not pushing mine hard but so far it has been my most accurate rifle.
3 in a one hole smaller than a dime at 50 yards, 2 touching at 100 yards with the third I managed to pull it an inch up and left. Shot at a golf ball at 100 yards they all 3 would have hit. Not quite MOA, not that day. Not guns fault, its doing what it needs to do. Blame is all on this old shooter.
