Take it all cum grano salis including this
If you choose not to crimp, and it is a choice, you might want to check cases in the magazine for bullet setback under recoil - some say the gun recoils back and the cartridge doesn't so the front of the magazine hits a hammer blow to the front of the bullet. People have arranged magazines with shoulders to match the case and sponge padded center channels in some magazines to deal with these issues. I wouldn't fiddle with the Steyr magazines here nor do I think it necessary, just making conversation.
In a Steyr Scout or as here strictly speaking pseudo Scout there is always the possibility of leaving a loaded magazine in the butt stock for many shots either single loaded or refilling the front magazine only for a series of shots - something to think about. For all I know you have a Pro Hunter or something else but I gather it is a Scout, mine is.
I started some time ago by reading Why Not Load Your Own by Townsend Whelen and Principles and Practices by Naramore and Phil Sharpe's book - the only experts I've read who had all the answers were the Herters
Of course Herters is out of business and Rock Chuck Bullet Swages just keeps chugging along.
Notice the variety of seating die arrangements - including the RCBS Vickers type, the many variations of sliding sleeve and the Redding shell holders of varied lengths and however likely it be that there is a best process for your equipment you may be sure that somebody else is getting good results doing it differently.
More specifically 7/8-14 threads as used are somewhat sloppy and the notion is that the shell holder face is square and normal to the ram and stroke and the die face is square and normal to the centerline and the die is symmetric and everything will line up peachy keen when butted and so produce a cartridge with minimum run out and maximum accuracy. After looking at your loaded ammunition and doing whatever you care to do for an estimate of runout you may choose to start the bullet then withdraw the ram and rotate the cartridge case a half turn or whatever before seating the bullet to final depth. Often this helps, sometimes it hurts.
Then too did you check the cases for overall and neck length? square the mouth and chamfer or take it that new cases must be the perfect length?
