Hornady FMJ 200gr / N105 / CCI 350 LP Magnum

Equipment/conditions:
- Glock 20
- IGB custom barrel 4.6" with full supported chamber
- primers: CCI 350 LP Magnum
- recoil spring: DPM MS 3-spring system for Glock 20/21
- firing pin spring "Red - 28 Newton"
- powder: Vihtavuori N105
- bullets: Hornady FMJ 200gr
- brass: Starline (new)
- OAL: 1.266
- temperature: 30 F (-1 C)
- 1 string: 4 shots
- distance from 1st Chrony screen: 3m (approx. 10 feet)
- I cleaned barrel quickly with brass-brush and hard-plastic brush after third string (after 12 shots)

load (grains)~~~~~average (fps)

11,0.................1216
11,2.................1218
11,4.................1225
11,6.................1242
11,8.................1264
12,0.................1289 primers flattened a bit

IMO the last load w. 12,0gr is safe in this configuration if barrel is clean and temp. is low, speaking of course for MY aftermarket IGB barrel with full supported chamber and considering that after approx. 500 rounds it has less friction or better said, it's a bit broken in.
My woods carry load against feral boar carrying light body armour will be 11,8gr

Warning: Do not try such loads with unsupported barrel or at higher spring/summer temperatures.
