    Looking forwarding to the experience and feedback that appears to be present on this site!

    I currently looking for any advice and feed on loads and tuning my most recent purchase.
    My recent purchase, Cooper M52 LRX chambered in 26 Nosler w/26" fluted barrel, long range stock & Vortex Viper Gen II FFP 5-25x50 glass. I started with Nosler ABLR 142gr. factory loads shooting several shocking 2+" groups. Went to handloads of 143gr. ELD-X with various charges from 81 to 85 grains of US869. Received similar results or at the very least nothing even close to the rifles factory testing card that would indicate that I'm even n the right ballpark.

    I've reached out tot both Cooper and Alliance (powder indicated on test card) but have not heard anything after a couple days. Any advise/direction would be welcome!!

    Mine shot sub .3” with Retumbo and 140 VLDs and sub .5” with US869 and 127 LRXs. Best accuracy around 3360 with VLDs and 3400 with LRXs although I did have some .6-7” groups at 3500 with the LRXs. Mine was a custom build, not a Cooper!

    Did you clean the barrel of all copper jacket material prior to trying the AccuBonds? I haven't shot the ABLR's but the originals are notorious for fouling especially when not shot in an absolutely clean barrel. I'd start over with an absolutely clean barrel now.
