Re: Barnes X

Bought a box of Barnes XBTs in hopes of doing some prep work for this season. Was warned that they were "finikie" but was supprised by what happened.

Accuracy was a bit off but pressures were high to the point of blowing primers with what has been pretty much a standard load for 140 gr Hornady/Sierra Game Kings etc.

Dropped powder and still blew a primer.

Did some measureing. Diameter fluctuated from < .277 to > than .277 and were way out of round.

Figure they would work well if I dropped velocity off a couple of hundres FPS but I'm not going to settle for that.

Just my tho'ts.
I may be the slowest guy on the mountain . . . . but . . . . I'm on the mountain!

Re: Barnes X

Range results from earlier today

My buddy and I were able to get the Barnes 165 gr X-Bullets down to a consistent .340 group @ 100 yards. But we still have a bit more work to do on the velocity.

We used 40.5 grains of IMR 4895
Comp length 2.235 with the bullet touching the lands. Having the bullets seated into the lands works best with my rifle
Muzzle velocity was 2607 fps with a standard deviation of 18 fps
Muzzle velocity was about 175 to 200 fps slower than the 168 gr AMAX and Sierra BTHP. That will be next weekends project to see if we can get the velocity up some more without affecting the accuracy to much

46 grains of VarGet gave a consistent .50Ē groups with the Barnes X bullets.

We couldnít get the 168 gr AMAX bullets to shoot any better than the mid .4ís to .5ís. Iím giving up on them and going to the Sierra 168 gr BTHP bullets.

Best group of today and my life. .153Ē group at 100 yards. It was one ragged hole. Overall average groups with this load are in the low to mid .2ís.
46 grains of varget
Sierra 168 gr BTHP
Comp Length 2.269 seated into the lands
Muzzle velocity of 2795 fps with a standard deviation of 16 fps

Thatís it for this weekend. Iíll let you know next weekend if we made any improvements.

Distance is not an issue, but the wind will make it interesting!

Re: Barnes X

Off topic a bit but curiosity got me. I looked and had 9 different boxes of X bullets here. Both coated and non coated. No TS though. From about 10 years or more ago to a box less than a year old.

Regardless of whether they shoot in all guns or not(have found a few rifles that don't like a certain type of X bullet- this is true) I wanted to measure them.

Measured about 20 out of each box. Average variance out of size and round was less than .0003 Then went and measured the match bullets I use in competition. Berger, JLK and Sierra. Both old 30 cal and a number of different .224 ones. Average out of round and off size .0002

I don't doubt that bad bullets from anyone can get out though. But that measuring put me at ease figuring the box that Roy measured was a plain fluke.

Roy-- send em back and get a replacement. Never did that with Barnes but have had to do it with Sierra and Hornady. Works out fine. No one is perfect.

Get as close as you can, but utilize your skills as needed.
