I met a guy 3 years ago at the range with a rolling block, he let me shoot it, been having thoughts ever since.
Im considering a 1860s 12.7x44R Remington rolling block. I see using 500 linebaugh, or 500 alaskan brass is a realistic option. Some talk of trimming but dont mention a length. Clearly a chamber cast is in order, just trying to get more knowlege before jumping in. Which mold are you using?
Any handloading advise, or wait for another caliber?
Speaking of groups have any targets to share?
Id be happy hitting milk jugs 9/10 times @ 75-100yd
