slow barrel

[Bang4theBuck]

Underperforming ammo is a known thing in 6.5 PRC, especially in Hornady. Too bad you aren't interested in reloading, you could gain back the performance that the cartridge is capable of.

Your method of establishing dope is fine, and better than most guys take the time to do (not counting us geeks of course), kudos to.you for.making the effort.

The chronograph your buying will give you very accurate velocities at the muzzle. This will highlight the next problem with ammo manufacturers......their BCs are often overstated too!. Atleast you will know exactly what to adjust in your ballistics app.

In my experince, ballistic software algorythms are approximations, especially when you are trying to true your data out to 1000 yds and beyond. My 6.5 PRC is shooting 160 gr. Matrix VLDs at 2,950 fps. This has been verified over two different chronos. However, when I "trued up" my data input with actual results I was seeing on the targets downrange, the program automatically dropped my muzzle velocity by nearly 200 fps to make the software results fit my actual downrange experience. It could have left the initial velocity input of 2,950 fps alone and adjusted the bullets BC, but I guess it is just easier for it to adjust the velocity. Don't worry about it. Your barrel is most likely not slow, but rather your ballistic software is compensating for its algorythms not quite matching actual results.

Chronos are nice tools to have but as mentioned above, targets don't lie. Consider conducting your trajectory validation test a second or even third time. If you get the same drops three times in a row and have shot at to your maximum range, it really doesn'tmatter what the chrono says.

Is it a new barrel?

I probably have 250-300 shots through the gun.
