Radical Short-Neck Case Really Works — Ware’s Wolfpup Wildcat

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…

Retired gunsmith Stan Ware is a talented shooter who’s not afraid to think “outside the box”. Stan competes in both Hunter Benchrest (HBR) and Varmint for Score (VFS) disciplines. In his quest to build the ultimate Hunter Benchrest cartridge, Stan created the radical “Wolfpup” wildcat, based on a 6mmBR parent case. Noting the dominance of 30 BRs in VFS matches, Stan wondered if a stretched 30 BR could work in HBR competition. The challenge was case capacity. Under HBR rules the cartridge must hold at least 45.0 grains of water, equal to the capacity of the classic 30/30 case.

To get the requisite HBR case capacity, Stan figured he needed to boost the volume of a 30 BR case significantly, so he would have to move the shoulder forward — a lot. He did this by running a 30 BR reamer deeper and deeper, test-firing brass along the way. After three reamer passes, he ended up with the capacity he needed (the Wolfpup holds 45.3 grains of water). But then he looked at the finished product — a case with almost no neck, and he wondered “how could this possibly work?”.

From Trashbin to Winner’s Circle
Ware’s prototype Wolfpup ended up so short-necked, so unlike any “normal” cartridge, that Stan figured it was “dead on arrival”. Stan told us: “I said ‘this ain’t going to work’ and I threw the brass in the trash can. Honest. But later I thought I better shoot it and see what it does.” There was one problem — Stan didn’t have a seating die. He noticed the short neck provided a bit of tension after fire-forming, so he literally seated some bullets, BIB 118s and 125s, with his fingers. For powder he used H4198 and started with 35 grains, one grain more than a 30 BR load. Stan then did a pressure work-up: “I actually went up to 41.0 grains and didn’t have a sticky bolt. I ended up at 37.9 grains of Hodgdon 4198 — that gave 3150 fps, where the sweet spot is.” (Later testing revealed a second accuracy node at about 3020 fps, using 36.4 grains of H4198).

Stan’s radical short-necked Wolfpup shot great from the get-go. Once he found the right velocity node, the gun shot in the ones and zeros with both 7-ogive and 10-ogive bullets, both 118s and 125s. The Wolfpup proved easy to tune — it’s not finicky at all. And it’s a winner. Stan began shooting the Wolfpup in 2006 in both VFS and HBR matches and the ‘Pup’ started winning matches right away. In 2007, Stan won the Wisconsin State VFS Championship shooting the Wolfpup. In June 2010 at a Webster City, Iowa VFS match, Stan won the Grand Agg and posted high X-Count for the match, while placing first at 100 yards and second at 200 yards. How’s that for a cartridge that almost ended up in the trash bin?

Does Stan deserve an award for “most innovative benchrest cartridge design”? Stan chuckles at that notion: “I’m not a hero, not a genius. I really didn’t do anything. The fun part is thinking outside the box — for me anyway. Shooting is an age-old process of experimentation. You never learn it all.”

Why Does It Work?
How can such a radical case design perform so well? “That’s a good question,” Stan admitted. He then explained: “The 30 BR is inherently accurate, so I figured something based on the 30 BR should be accurate too. My personal belief is that the short neck doesn’t hurt you. Plus if the throat in the barrel is straight, the bullet can self-align. If the chamber is good, the bullet will self-center in the throat. In a regular case there’s not much room to do that, so a bullet can start off-center, and you don’t get the same results every time. A bullet in a conventional case is stopped from self-centering by the stiffer neck, particularly in a tight-clearance BR gun.”

Reloading the .30 Wolfpup
Stan’s Wolfpup chamber has a neck dimension of 0.330″. He turns his necks for a 0.327″ loaded round. Bullets are jammed .020″ forward of first contact with the lands. When he closes the bolt it pushes the bullet back in the case — almost a soft seat. Stan notes: “To start with I normally bump the shoulder .0005-.001″ so they go in easy. Just by doing that I get a little neck tension. I also use a bushing. Right now I’m running a .322, but it’s not particularly sensitive. I’ve tried one-thousandths increments up to a .325 bushing and couldn’t tell a lot of difference.” For bullet seating, Stan uses a Wilson 30 BR seater die into which he ran the chamber reamer. This gives perfect case fit during seating operations.

About the Illustrated Gunstock
You’ll notice Stan’s stock contains scenes from Vietnam and a quotation. Here’s the story. A Vietnam combat veteran, Stan served “in-country” with the Army’s 509th Non-Divisional Combat Unit (out of Fort Riley) from 1965-1966. Shortly before he left Vietnam, Stan went to a shop to have a souvenir lighter engraved. He asked the vendor for an appropriate inscription. The shop’s metal-worker engraved: “War is a tragedy. It takes mans’ best to do mans’ worst.” That message, along with the combat scenes, were hand-painted on Stan’s rifle by his wife Susan, a talented artist. She spent more than 20 hours painting the rifle stock.
