9mm 1:10 twist barrel, 115 and 125 Brazos data?
Curious if anyone has tried the lighter 115 and/or 125 Hi-Tek coated bullets in a 1:10 twist (1911?) barrel? Theoretically...way over-stabilized, but can they still group? MVs? I get okay results with 147 gr CRN Hi-Tek bullets, however, I was looking for 50 yd or 25 yd data for their lighter weight CRNs.
I was thinking about it in terms of my service rifle: the 1:7 twist barrel is great for 77 and 80 gr Sierras, but it also shoots 53 gr Sierras very well at similar MVs.

Try them and find out. My CZ SP01 has a 1-10 twist and shoots fine.

With Atlanta Arms 115 match, I've shot groups at 25 yds from 10 twist kkm barrels that clover leafed.
The fast twist barrels group at 50 yds with standard/typical velocity ammunition in 9mm, 38 Super and 45.

Walther PPQ, SWC is not good, 147gn Brazos is not good. My gun really likes RMR Match Winners so I am sticking with those, +1 on the Atlanta Arms.
