I’m looking to start working on my first wildcat. I’ve been reloading for about 10 years now so I have quite a bit of experience there. I’ve just never done a wildcat. Any advice on what I should look out for and potential dangers that differ from loading a standard SAAMI spec case? My game plan is to make a 25 wssm ackley with 40* shoulders shooting the 133 Berger’s. I’ve heard the Winchester brass is pretty thick, I know I’ll have to turn the necks. I’ve gotten pretty good at reading pressure signs so I’m not to worried about working up a load when my brass is fully preped. I’ve also never had to fireform anything. Any advice would be greatly appreciate
Thanks very much Mike! This helps a lot!!. I already have my action so I’m kind of stuck with what I have. It’s a Terminus Zeus. I’m been worried about using Winchester brass. I’m guessing if I weight sort the and do all the prep work they should work fine huh?
I've noticed that you have mentioned Winchester brass a few times in your replies. I am not a fan of Winchester brass as I get only 3-4 reloads out of it before I have to start over again. There are not any signs of pressure at all, however the primer pockets seem to loosen up on the brass. I just got some Norma brass and hoping to get some longevity out of that brass. I'd like to find some .280 Remington Peterson brass, however at the present shortages that isn't going to happen any too soon. I built a couple of .270 Ackley Improved rifles a couple of years ago. And that was "because" I wanted to try reloading for a "wildcat". It is a great cartridge with some incredible ballistics, however.............I start out with load data from the .270 WSM and have found that the performance is close to that of the .270 WSM. With that said, if I had it to do over again I would probably build a couple of .270WSM rifles instead of the .270 AI. If you have the time and money to dedicate to fire forming/hydro forming, annealing, neck turning and all that goes into a wildcat cartridge, then by all means go at it. I was seriously looking at the .280 Ackley Improve (SAAMI), however didn't go the build because I felt that Nosler was going to hold everyone at their mercy with component prices, and.......they have. Right now .280AI brass costs more than the 28 Nosler brass and is a little more difficult to find. I know that I am talking about a different sized cartridge than what you are planning to build, however the work that one has to put in to making the brass is the same. Also in my particular situation and what is going on with the heavier .270 bullets I would have selected a 1-8 barrel instead of the standard 1-10. So.........as a suggestion on a wildcat build I would also take a strong look at barrel twist and the availability of bullets as well as the availability of the brass to make your wildcat casings.
