I was gonna use them out of a 10/22 and a 597. Try to tighten up the inadaquacies(?) typical of those semis.
I still have a few thousand in the federal bulk paks, as well as about 11K of the remington cyclones.
Fassteel, those Lapua 22s shoot about 4 inches lower then the Federal bulk pak shells at 50 yrds out of that CZ. I was quite amazed at the difference.
I had about 30 of the Lapua left when I went to the 100 yrd range...Dropped all but about 5 inside a 3 in circle with the CZ. Mind you....I had to do about a 14 inch hold over.
