Rex 3 and 160gr Target bullets

Loaded yesterday, shot today, very fresh ammo
So, here's data for Rex 3 and 160gr Target bullets (nickel plated).

- Glock 20 stock barrel
- primers: CCI 300 Large Pistol
- recoil spring: DPM MS 3-spring system for Glock 20/21
- powder: Rex 3 alias Rex Green
- bullets: Target 160gr nickel plated
details: product "cod TM4Platinum/400" at http://www.targetbullets.it/platinum...ts_709227.html
- brass: Starline and Winchester (both new)
- COAL: 1.260 and 1.263 (last 3 loads)
- temperature: 50 oF (10 oC)


load (grains)~~average (fps)
7,7.................1078
8,0.................1085
8,3.................1113
8,6.................1163
8,9.................1186
9,1.................1200
9,3.................1218
9,5.................1221
9,7.................1240
9,9.................1248
10,1...............1255
10,3...............1268

At 10,3gr of Rex 3 the case is almost full and powder becomes compressed quite much. Perhaps could go to squeezed 10,5 or heaviliy squeezed 10,7gr but I'm sure that 1300fps wouldn't be reached anyway, so nothing to write home about it. I don't recommend to use any heavier bullets because Rex 3 is too fast, neither some expensive bullet like Speer Gold Dot 155 or 165gr because you will be making mild/target loads that cost too much.
Anyway, if you shoot 10mm a lot and have some lighter non-expensive bullets, Rex 3 is very interesting because of its price.
