New Wildcats

Grimstod

Machinist, Designer, and Shooter.
Ever since the great ammo recession (maybe I should say depression) of 2020 hit I have not been able to get very many components. And I feel like I have fallen behind on the development of wildcat cartridges. I love this topic of making things better through wildcatting. If that's possible. Has anything new or interesting come out since the 6BRA?

Here is one I worked on a few years back. Components are so short though have hardly been able to do much in testing.

Howdy !

This is just a few comments on wildcatting, that I'll share with reviewers:

Working with wildcats of my own design, and especially... trial forming forming wildcat cases has been one way for me to keep my hand in things; even though my range shooting has slowed a bit over the period mentioned. And when I do get to the range for load testing, I will most often be shooting one of my wildcats.

Just thinking:
I think anyone wanting to shoot a SR-primered case these days, might want to at least consider using a LR-primered version of the case they shoot; in such instances where a LR primered itteration of the case is possible ( 6 X 47L, 6mm Creedmoor in example ). This itself might technically be " wildcatting "..... in a broad sense. The reasoning being..... it could prove easier to obtain LR primers than SR primers, overall.
The popularity of factory chamberings & wildcats for AR's drives a huge portion of SR primer demand IMHO. And yes, I know.....high volumne shooting competitors often demand SR primers in their chosen chambering, as an adjunct to stronger case heads; and perhaps by extension... longer life for those expensive cases.
That on its own, is not a death sentence on the potential accuracy level for a LR-primed cartridge.
Again.... just sayin'.

I think wildcatting for some shooters in some circumstances might be a way forward in support of their shooting needs. For example..... if you can't get 6mm Remington cases and that's the case capacity that you still want, you might form a 6mm wildcat on a " parent case " that provides you with the same 55gr H2O case capacity the 6mm Remington did. Such things are not " beyond the pale ", even when specifying .308 bolt face compatibility. After all, wildcatting.... historically.... has largely been about reaching a certain case capacity; desired for a certain calibre. And also sometimes..... doing some select case shaping in select circumstances; for the percieved benefits.

Don't want to wildcat ? Not for you ? Too much time & effort ? Understood.
Hey, nobody's gonna make ya !

Wildcatting is so addicting though. I think since I started doing them I have yet to chamber a standard cartridge since.


You are right about case life. If the brass you get is consistent most likely it will be $$. Also the longer you can use a case should also imply that the case metallurgy will change less from reload to reload.

Now why a smaller primer case tends to last longer compared to a LP case, that is just because there is more metal around the primer pocket.
 
Confirmed and addicted with the wild catting hobby, and I take
what I make to match's. The 284 Winchester case has been my
primary case to work with. A short version I call the 284-ELF was
put away due to component sourcing, of which the BR2 primers
were needed for this past match season in another cat I've been
competing with. One match left this year and the ELF will be back
on the bench.

the three cases in the pic, you said one is a straight 284, one is a 284-ELF, what is the other?

Only thing that would shy me away from the PRC is the horrendous quality of Hornady brass. When I cull their brass I end up throwing out 70% it seams.
Our good friends at Lapua have solved that problem for us.

Well I am behind on things. Did not know they were making brass. Then it is interesting. If only the neck was not so short. Might get a little longer in a 7mm version though.

Is that a 6mm/225 win?
 
Some day, take a Lapua and a Hornady case, both of the same cartridge size, cross cut them and check out the thickness of the base/body. You might be in for a surprise.
This is so not true. Brass that is soft no matter how thick it is is not worth squat. The important aspects of brass quality is getting it soft in the right places and hard in the right places too. Not easy to do.
 
The 7-6.5 prc is about 3 years old. It will take over in f open imo. The 6bra dates back to the 80s. It just had to break a bunch of records to become popular. You almost need a new parent case to have a new wildcat.
Alex,
I had no idea folks were running this in competition. The minute I seen one of the 6.5 prc cases on the ground at out local range, I immediately thought it would be a dandy in 7 mm.
Did you change the shoulder angle? Are they running the normal 284 speeds with heavies or a step up?

This is ending my 4th competitive shooting year (I've reloaded for decades but just load whatever I was shooting). Wildcatting is so intriguing but at this point in my life I'll let y'all make it and I'll follow suite! LOL Really some of the stuff we have now is going to be really hard to improve on! JMHO (but I'm limited in knowledge) :cool:

They run 2930, I didn't change the shoulder because I didn't want to increase capacity.
