OK, let's see how these 69g puppies fly sitting on top of XBR. Am looking for <span style="font-weight: bold">ONE</span> load to quantity-produce a really sweet 100-300 yd. combo and stop screwing around in the "mad-scientist lab" everytime I make ammo.
Cooked-Up 15 rounds each of 6 different charges in Hornady LNL-AP. Obviously VARGET and RL15 are the team favorites but those powders just meter so poorly through progressive that it become a trickle-weigh and pour drill for consistent charges. Am looking for something that will be damned-close in accuracy at 1-3 hun. Yds. so we will give this XBR a spin.
Metering was quite good in progressive with almost all charges in +,- 0.1g. A few +,- 0.2.
Started at 22.0 then 22.7, 23.2, 23.6, 23.9 and 24.3 as target weights. Have Chrono and will report back. I am going 0.1 over at 23.9 and 0.5 at 24.3 as I read multiple acounts of the IMR-Hodg. published data being too-conservative for observed pressure-signs.
Hopefully, somewhere in the 23.6-24.3 range I will find a sweet-grouping load that still has good bullet speed.
If this pans-out then I probably will be set with the user-friendly 8208 XBR and the sensible-priced match bullets in those 69g Nosler Custome Comps.
Rifle is 18", 1 in 8 twist, Shilen ultra-match barreled, SPR config. with Viltor Upper and Billet Lower with Fail-Zero BCG. It's made of good parts and has been a real 1/2-3/4 minute tack-driver with hand-trickled loads of 24.3 Benchmark and 53g. VMAX's.
Stay Tuned
