BCL TRS Bronco Howitzer .308 range expectancy?

[flintyboom]

What kind of accuracy do think I could expect, and what would your max range be to hit something like a 12" gong? These have a 9 1/2" barrel, so I don't know what limit that would put on its potential.
I have a Remington 700 precision. 308 with a 26" barrel that is a good 800-900 yd gun. Is that distance cut in half with this? Any opinions or experiences are welcome. Thanks

Go to JBM Ballistics and play with the velocities and ballistic coefficients:

Mine shot sub MOA with a 12.5 inch barrel at 100. YMMV.

Thanks for that info. Have you tried it out at longer range? My other .308 loves 168gr bthp around 2700 fps

I only tried it at 100 with 150 grain Speer Gold Dots. Fun rifles!

With the right choice in bullet and load your rifle is easily capable of 1400 yds and maybe further. I shot my 20" 308 to 1200 yds.

It didn't like anything heavier than the 168s. I tried the 175s and 178s, but could never get them to shoot well with the 1-12 twist. My data showed it going transsonic around 900 yds
