Short neck 30br article

[Geno C]

I remember there was an article on this site about a 30br and that neck was shortened or the shoulder pushed forward until there was basically no neck. I can seem to find it. Any help would be appreciated

6 Norma Dasher Improved???

anybody taken the new Norma Dasher long neck brass and blown the shoulder forward ?? it should make enough room to bump up from 36.5 to the 39 to 39.3 grs range of H4350/ RL17 which could maybe be worthwhile with the new 110 SMK or 115 DTACS. any thoughts ??

You're probably thinking about the 30 WolfPup that Stan Ware and myself developed. I had the first one out of Stan's shop and did the case and load work for it in my gun. Here's some pics I took during that process.....some which appear in the article linked here about Stan. The 5 shot group shown was shot on the very first range session. There's a lot more of course....but this will get you some of the basic info on it.

PS- The tag line "It'll never work" came from Randy Robinett when I sent him a picture of the fire formed case.

Think you need a relatively long case-neck for good accuracy? Think again. Stan Ware broke all the rules with his radical Wolfpup cartridge, proving that a near-no-neck design can deliver match-winning accuracy. Read on to learn how the Wolfpup works... <img class=alignright...

Famous words, been said many of times over history.

Have you tried a modified version with a little more neck and less body?

This was conceived back when the NBRSA still had the minimum case volume rule for HBR. It met that minimum of the same volume as a 30/30.

While there were many attempts from other shooters to replicate this feat, I always thought this was the most ingenious.

Jackie, we continued to refine the case quite a bit from when that article was done.

The short neck means it has to seal instantly so lighter loads really didn't work out. As to neck clearance, my testing showed better 200 yard results when the neck clearance got very close to zero. I still sized with a bushing for neck tension but the necks are close to a guage fit into the chamber. In firing, the neck ring ironed out a bit against the chamber and we had no issues with the pressure ring grabbing the inner neck as the base of the bullet moved through it. The base of the bullet at the 'touch point' to the rifling ended up .050 below the neck/shoulder junction. I ended up shooting my 1.00" jacket 117's at 3,210 from several different barrels.
