A good friend and I headed out predator hunting. Lots of coyote tracks, some Lynx, one wolf track at our first spot, but no action. Weather wasn't ideal, +2c and windy as hell. We headed back to the truck and drove to a spot I found on google earth and wanted to try. There was a fresh Lynx...
What we have here is Winchester, a competing company to Hornady, bringing out a similar performing cartridge to the 6.5 PRC. Like the PRC, the 6.8 Western is SAAMI spec to succeed. Factory ammo with heavy for caliber, aerodynamic bullets, working in factory rifles. A heavier bullet option to...
No high pressure signs with any load except an ejector mark on the highest IMR 4955 load
Varied from below 10, to 40-50 fps on 3 shots
All these loads were in virgin brass. Now that the batch is all formed, I will anneal, bump shoulder .002", trim, uniform pockets and flash holes, then get...
Should receive a couple of them next week. 26" 1:7 twist, one on a Tikka t3 and the other on a CRF m70
75Amax, 75 Scirocco, 77 LRX, and 88 ELD will be the bullets. Lots of promising powders - RL26, RL23, RL22, H4831sc, Magpro, RL19, RL16, H4350
Last weekend I tested the cold gun/warm gun difference. Day 1, cold rifles (-2F), Day 2, warm rifles (72F). Ammo was cold (-2F) in both days testing
Ammo left outside overnight in temps of -25C (-13F) . Was exactly -19C (-2F) when I shot, same as day before with cold gun/cold ammo.. Rifles...
Interesting data below. Ignition consistency suffers in the cold on average. But that doesn't explain to me, the increase in velocity. Just shows a sloppiness of velocity
223, Dominion small rifle primer (Russian manuf.)
Standard deviation of 27 fps at +7c, and SD of 36 @ -19c

Day 3 test, ammo left outside overnight in temps of -25C (-13F) . Was exactly -19C (-2F) when I shot, same as day before with cold gun/cold ammo.. Rifles were left inside all night, loaded into warm truck (heater set to 22C / 72F) and left inside the idling truck until ready to shoot.
Ruger...
Day 2 , -19C (-2F) . Rifles/ammo had been outside for hours. So cold they burned the hands packing them to the truck. Another 10 minute cold ride with a warm bum to the range, where they were set outside in the shade.
Ruger m77 Scout 223, 55gr Hornady SP, 21.8grs IMR 4198. In +20c (68F) to...
Well this started out as a quick test of two rifles I hunt deer in November with, to see how sub zero temps effects the load specs. I grabbed my 280 Ackley and 6.5 PRC rifles & ammo, and set them outside for hours at -16c (3F) Also had a few rounds of 6.5 Creedmoor I wanted to blow off so set it...
