.25 cal 131g .330G7 bullet from Blackjack Bullets for you to drool on ...

How bout them .25 bores? We are taking one this weekend trophy muley hunting in the rocky mountain high country.

Thanks for bringing it back to the regularly scheduled programming. Now that you've leaked, we expect an action report on the capabilities of .257s.

Back on topic...

If I was to get a quarter bore...I have tons of 270 Wby brass and tons of 2.65-284 Norma brass...

If I was to get a .25 barrel...what case would have less of a chance to get "donuts" if I resized the neck?

I like the length of the neck on the 270 Wby brass...

don't buy into the long neck kool aid, they cause nothing but problems with bullet run out, bullet tension that causes pressure spikes, high sd's and es ... bullet diameter of cartridge is all you need for neck length, longer necks DO NOT promote more "barrel life"

So it sounds like a 25-284 is the go to case in this in a long action with a long throat...

25x47 Lapua!
6.5x47 parent case.

Okay...Have to agree...however, the 270 Wby with a 28" barrel spits out 140gr SSTs @ 3625fps...130 SSTs @ 3680fps...without any load development...

A 257Wby with the same length barrel may be really fun...with the 131gr bullets...

This is what we are taking. This little case is simply amazing!

in low pressure cartridges longer necks are not a problem but in cartridges that run in the 60+ k psi range, longer than caliber length necks will show pressure signs earlier than shorter necks, erratic sd and es with unexplained flyers was common from what I have seen in several of my wildcats, it gets worse the more overbore the cartridge

I've scrapped all my long necked 338 NM based wildcats in favor of the shorter neck versions, they perform much better with the exact same data, velocity spreads have become tighter, low single digit sd is easily attained and can load a bit faster with no pressure signs

Obviously it was the design of your cartridges or it was the calibers chosen because I've run thousands of tests using the 6mm Rem. in various versions of neck angles with the original long neck length with nothing but great results.

I have a 25-284 being built right now. Long action 700,Krieger 1-7.5 twist my reamer has .145 freebore. If I don't have the 131s soon. In going to work up a load for 115 Bergers as they kick *** outta my 25-06. I've run all my Lapua 6.5x284 brass through a Redding 25-284 fl die. No donuts, easy as pie running them through the dies

Long versus short neck. Interesting discussion. I'm aware of the pros/cons claims. Have no 1st hand experiences to support one or the other.
It seems like it would require a LOT of experiences with cartridges of both neck length versions. Swamplord has been accumulating a lot of that experience in more than one caliber. So the caliber length rule of thumb seems the happy medium.

Until you examine Stan Ware's short neck benchrest cartridge, The Wolfpup. As with most most dichotomies, there are exceptions to any rule somebody wants to make.

You have some cool wildcats and a kickazz names to go with it. Always enjoyed reading your posts. Those real world experiences and applications outside the norms are cool stuff.

Cheers!

It's hard to argue with results like that. I agree with your statement "As with most most dichotomies, there are exceptions to any rule somebody wants to make."
