I thought this was lost, but came onto it when looking for something else today. This was shot after I finished tuning my Ruger 10-22 Deluxe that I'd accurized and re-barreled with a Shilen Bull and replaced the extractor with a Clark extractor (I'd since modified factory extractors for some subsequent jobs). Done 19 years ago. It obviously likes Lapua Master ammo.
This target was supplied on-line for a Prove-It test of rimfire rifles, posted on a website. This target had the best average group size for many weeks, until someone with a super match rifle beat it out.
