Redding Competition Bushing Neck Sizing die improves my groups by 50%

[Jicko]

I couldn't believe it.... but just merely using Redding Competition Micrometer Bushing Neck Sizing die... I shrinks/improves my groups by 50%.... vs the regular Redding Neck Sizing/FL Sizing die...

Back to back testing.... 8 groups of 5 rounds each... same powder, same primers, same cases, same bullets... 100yds testing...

(if you don't already know..... 700PSS .308WIN.... 175SMK ~2650fps.... FC brass)

The 4 groups that was done with the Redding Competition Neck Sizing die (even at various neck sizing depth, ie. 1/2 neck sized, 2/3 neck sized, 3/4 neck sized and full neck sized) are consistantly 50% better than the 4 other control groups (which are all done with Redding Regular Neck Sizer or Regular FL Sizer, 2 groups each)

Edit: all rounds are seated with Redding Competition Micrometer Seating die

Those dies are expensive for a reason...they work and they work well.

but I couldn't believe my eyes... when I see the consistant shrink in group size! i am shooting them back to back in alternating sequence....

and the 4 groups are just... 50% smaller!!!

I use the Redding S type bushing dies and micrometer seating dies for my serious long range guns.

I use the Redding S type bushing dies and micrometer seating dies for my serious long range guns.

I use them for EVERY rifle. They produce great ammo, and extend the life of the brass, so pay for themselves in short order.
