.270 win 165 ABLR - unknown

[qmalone64]

Looking into rebarreling my howa 1500 (30/06) with OMR. Been intrigued looking at velocities/ performance of the 270 offerings on unknowns website. In particular the 165 and 150 grain ABLR’s. Curious if anyone has first hand experience with these? Looking for velocity info from 22” barrel. I assume the advertised velocities on unknowns website are from a 26” like their other cartridges state. Not a reloader at the moment so looking at these as well as the federal term. Ascents.

Atleast until i buy a tikka in 223 and shoot tmks…..

Thanks!!

I built a 270 1-8 with a 20" McGowen barrel this year. Have not loaded the accubonds yet, but am getting 2890 fps with a 155 LRX.

30 fps +\- per inch of barrel a good estimate you think for velocity reduction? Leaning towards a 22” barrel at the moment

Posted my fps question before reading yours. Thanks for the info. Run any heavy factory loads for reference? Not a reloader currently
