Welcome to Part 4 of the Saga of the .220Redline! Long before endeavoring to build this wildcat, I’ve accepted that running a cartridge nearer the edge of traditional reasoning is not without consequences. Sparking off almost 70 grains of smokeless powder down a .224 caliber hole is rather extreme!
… all three kills were nearly identical: a .224″ entrance, Jell-O-lungs, and a modest exit hole…
…With Berger out of the market and no longer providing the required J4 jackets to the custom makers, finding 30’s on J4’s is mostly a game of buying up old stock… So, when I heard from Montana Mize recently that he had worked up a new 30 gr. flat base design, I was definitely interested! I got him on the phone and ordered a couple hundred of them to play with.
…for the guys wanting to neck turn for chambers that are not tight necks, be they factory or custom, the question of what thickness to turn to is a bit more muddy. Obviously, you don’t “need” to neck turn at all, for a factory or non-tight neck chamber. And of course, factory chambers are generously proportioned and sloppy of fit to begin with, so there is always concern for making things even sloppier…
There are several reasons you might want to outside neck turn, even if you don’t have a tight neck chamber. Probably the best reason is that neck turning is the “easy button” to producing excellent concentricity.
CPS stands for Competition Primer Seater. The original CPS from Primal Rights is a stand alone, bench mounted primer seater…
I got the idea to section a bunch of bullets at once for a picture gallery. Finally getting around to it!
I got a Lyman borescope recently and the first barrel I wanted to look at was this one. What I found was horrifying. Just gawd awful carbon fouling…
…Bullet selection would be from various 69-80.5grain bullets on hand, from Hornady, Berger, Sierra & ‘Swampworks’ line of custom JLKs… Then, I set out about seeing how fast a 75 JLK might go. Turns out, RL-33 yielded a whopping 4088 fps! That load showed…
Many .17 shooters have long considered the 30 gr. Gold that Todd Kindler of the Woodchuck Den used to make as “the” bullet for coyote with large capacity .17’s. But a few years ago, Todd stopped making his fantastic bullets. The dies along with a supply of J4 jackets of the correct length for making the 30 Golds are back in production and the 30 Gold is available again!
