I know this is going to show my ignorance (tryin to learn sumpin )but there are numerous cases that fit in contender platform but dont seem to be used. A couple of examples are 30-40 & 303. Brass is readily available for these rounds and should make decent parent cases? no? There are a lot of others that would fit into this catagory, why not use them?

Mike,
The 307 Winchester Improved case is a great one, since it is a strong design. You can get into pressure problems if you are not careful, but that is not that uncommon with cases for the Contender(You can use the 45-70 in a safely Contender, but you can't safely load it to the levels you can safely in an Encore). With the G-2 out it gives us a little more fudge room since it is a stronger frame.

Ernie, True but i am talkin about staying within the pressure constraints of the contender package. There are numerous other cases that would fill the bill but seem to be ignored (or maybe i just have not seen them), my question is why?

Ditto to the above Mike. When we first heard about the G-2 the first post I saw were guys wanting to shoot a full length 308 in it. The way I see the G-2 is as Ernie says , "a little more fudge factor" maybe. Bottom line it is still a Contender and should be treated as much, but we all know some one will push it a little to far.

Back to the original question, all I will say is I am working on it .
Jeff

So, maybe a reasonable question will be - What will a generally acceptable preasue limit be on the G2? Do I remember correctly that the Contender is around 55k? I don't watch the numbers that close so I could be wrong. Living where I do, even deer season has temp's around 90 degrees, so I have to keep preasure lower than most anyway.

Well, you have to remember that it breach thrust based on the case head size & pressure that determines the maximum pressure for the break opne guns.... So it is more of a pressure within a given case head size.

As far as my opinion is has to do with price of brass and what the experts try to make you beleive is the best ones. Then again everone looks for the cheaper brass. I think the 375 win is worth looking into, but then again, it is not as cheap as the 444. But i see where you are coming from. One reason I like the 30 Alaskan, load a 307 fireform load and your done, set the shoulder back a bit and you have a powerhouse if you want it.

i think it was 45,000 max psi.

I think the main reason those other cases are ignored for the most part is that a 30-30 case will do all a Contender can stand and then some. You will achieve maximum pressure and velocity with the 30-30. It shows pressure well, and it's dirt cheap. There really is no need for messing with the 303 nor the 30-40 unless of course you just like those rounds.

Good answer Jeff!

I have been playin around with the 30-40 as it can be necked straight up to a 41 caliber but other than that i really have no use for it, kinda like a short 405.

MSS, I've often wondered the same thing? I know SSK chambers 30-40 krag.

Why is the 225 win. used for so many wildcat with limited availablity when the 220 swift has always been more available? It also adds more case capacity.

I am working with sort of an experimental round right now. It is a .375 based on 9.3x74R. Also if you want it rimless 30-06 brass can be used.
the 9.3x74R brass is not cheap. The round was dubbed .375 Bellm Express. If you took a 375/444 and stretched it out from 2.25 to 2.375. A fired case measures .470 at the base and .458 at the shoulder. The shoulder is also moved forward .125. I've just started working with it. With the 270 Hornady I've got 2174 FPS. I will be working with it more and also the 225 Hornady.
