Seb’s Wild 6 PPC + .284 Win Fat-Bottom Hammerhead Convertible
You interested in a really wild, innovative bench gun that can shoot both short-range and long-range matches? Check out Seb Lambang’s latest “do-it-all” rifle. It’s a switch-barrel rifle combining two very different chamberings: 6 PPC and .284 Winchester. With that caliber combo, Seb’s covered from 100 yards (LV/HV mode) all the way out to 1000 (LR Light Gun mode). But the dual chambering is not the rifle’s only trick feature. Exploiting the new long-range benchrest rules, Seb has fitted a 3″-wide, flat rear metal keel to the buttstock. That counter-balances his 30″-long 7mm barrel, improves tracking, and adds stability. Seb built the stock and smithing was done by Australian gunsmith David Kerr.
Detachable Hammerhead Wing Section Plus Fat-Bottom Keel
To further reduce torque and improve tracking, the stock features an 8″-wide, detachable fore-end fixture. This “hammerhead” fore-end section has extended “wings” on both sides, making the rifle super-stable. The hammerhead unit can be removed, leaving the stock 3″ wide for use in registered benchrest matches where 3″ is the maximum width. The photos below show Seb’s gun in .284 Win Long-Range (LR) Light Gun mode.
Yes This Rig Shoots … In Both Configurations, Long-Range and Short
Seb has already used his switch-caliber, switch-barrel rig successfully in competition. Seb tells us: “The gun shot and tracked real well either in 6 PPC LV/HV mode or in .284 Win LG mode. I love it! With this gun I placed Top 10 for the Two-Gun at the Harry Madden Championship in Brisbane, Australia just a few days ago and took the silver medal for the 500m Flyshoot with the .284 Win on the next day. So who says a switch-barrel rifle can’t (or doesn’t) work?” And get this, Seb finished the stock just four days before the Brisbane match. He glued-in the action the evening before the match and shot it the next day in competition. Pretty impressive we’d say….

Seb Lambang — Indonesian Innovator
If you don’t know already, Seb Lambang is the designer/builder of the innovative SEB Coaxial rests. These are some of the best joystick rests on the market. The latest version, the SEB Neo Rest, is a brilliant design that folds flat for transport, yet offers extended vertical and horizontal travel and a rest top that can adjust from roughly 2″ wide to over 6″ in width. This Editor uses a SEB Neo for both bench and F-Class shooting and it is my favorite joystick rest. Rest in photos is a SEB Neo MAX.

So is it legal to shoot a 3″ wide butstock in LV 6ppc or sporter matches? Lee
There have been some discussions about how much recoil a glue in can take. I would like to know what glue he used, and if stock screws were used in addition to the glue in. Obviously, the level of innovation, and quality of execution are what we have come to expect from Seb. Well done!
Lee, I have shot 3″ wide buttstock at the Supershoot before this (using my previous “Swallowtail” gun), and it was legal / no protest etc at all. The same happened in Australia.
Concerning the stock width, the IBS/NBRSA/WBSF stock rules only says the stock must be no more than 3″ wide…(any part of it). — That’s why I made 3″ buttstock on my gun. It doesn’t break the rules in any way.
Boyd, I used Devcon 2 Ton White Epoxy (which has about 30 minutes working time), plus 2 alum pillars inside with two action screws (front & rear). It’s no way would break or loose, even for decades. (Removing the action from the stock in the future is another thing, anyway…perhaps I have to butcher the stock!).
Thanks for the kind words,
seb.
EDITOR: One point not covered in the article is that the detachable, 8″-wide fore-end extension adds 4″ of overall length to the basic stock. You can see in the bottom photo (added this morning) that the LV/HV stock version is shorter than the full-length stock fitted with the hammerhead extension.
Very cool indeed and thanks for the reply. Wonder why more free recoil shooters dont utilize this approach. The wide back end would have to help tracking, i would think? Lee
