Norm Crawford Wins Wimbleton Cup with Composite Barrel

Norman Crawford Proof Research Wimbleton Cup 2016 Camp Perry
Tech Milestone — Norm Crawford won the 2016 Wimbledon Cup at Camp Perry using a carbon-fiber composite barrel. That’s a first for composite barrel technology.

With a score of 200-16X, Norman Crawford won the Wimbledon Cup Match during the 2016 National Long Range Rifle Championships using a 32″ Proof Research carbon-fiber composite barrel chambered in .284 Shehane. The Wimbledon Cup Match, a prestigious 1,000-yard shooting competition, dates back to 1875. The current course of fire consists of 20 timed shots, fired from prone. Crawford’s win represents the first time in the Cup’s 141-year history that it has been won with anything other than an all-steel barrel. The Proof Research barrel features a steel core with an external multi-axis carbon wrap.

Crawford’s Wimbledon Cup win really is an important technological milestone. Crawford’s performance may encourage other competitors to consider steel/carbon composite barrels for a variety of shooting disciplines. Without question, composite technology barrels offer significant weight-savings over conventional all-steel barrels. And Crawford proved that a composite barrel can deliver winning accuracy, at least in a sling/prone discipline.

“I don’t know of anyone else in this sport using a carbon fiber [composite] barrel,” said Crawford, who has been shooting Proof composite barrels since 2013.

“The benefits over a steel barrel are that you get a larger-diameter, stiffer, faster-cooling barrel that weighs less than a standard, medium Palma-taper barrel. [There is] no real downside I’ve been able to identify in three years of shooting them. All five Proof barrels I own are capable of winning any match — providing I do my part.”

A 30-year Army vet and former Army Special Operations Sniper, Crawford has been shooting competitively since 1990. He has won many major titles, including the NRA National Long Range Championship in 2005. His 2016 Wimbledon Cup victory was his second — Norm also won the Cup in 2003. A three-time member of the U.S. Rifle Team at the World Championships, Crawford also used a Proof Research barrel to tie the national record for a 600-yard Any Gun, Any Sight competition in North Carolina last November, one of five national records he has set or tied during his shooting career.

Proof Research CEO Larry Murphy praised Crawford: “We are honored that Norm chose our barrel to go up against the best shooters in the world with. By putting our barrels to the test in intense competition, he pushes us to do our best as well.”

Carbon-Wrapped Savage Pre-Fit Barrels Now Available

Proof research carbon wrap barrels composite

Here’s a new barrel option for Savage shooters. Proof Research, a leader in composite barrel production, now offers “Pre-Fit” barrels for Savages. These barrels come chambered and threaded for Savage actions. Pre-Fits are easy to install — just spin them on, set the headspace with gauges, and tension the barrel nut. (Proof Research does recommend enlisting a gunsmith to help with the process.)

With a finished weight under three pounds, these new Pre-Fit barrels are much lighter than conventional all-steel barrels. Proof Research claims that they are “less than half the weight of comparably-sized steel barrels.” But you will pay dearly for that weight savings. As sold by Stocky’s Stocks, these Proof Research Pre-Fits cost $846.99, more than twice what all-steel Pre-Fit barrels from Criterion or Pac-Nor cost. Criterion Barrels currently charges $370.00 for a 26″ Savage or Rem/Age Pre-Fit.

Proof Research claims that its carbon-wrapped barrels shed heat faster than an all-steel barrel. Jason Lincoln, Proof Research’s VP of Engineering, claims that his company’s composite barrels can cool 50% faster than steel barrels, offering reduced point-of-impact shift during extended strings of fire. Is this marketing hype? We have yet to see a definitive test that validates the claims of enhanced cooling…

Proof Research Savage Pre-Fit Options Available
Initially the Pre-Fit barrels will be offered in a “Sendero” profile, very similar to an M24 contour. Available barrel lengths (up to 28″) vary by caliber/chambering (in some cases 24″ is all you can get). The following chamberings and twist rates are currently offered by Stocky’s Stocks:

.223 Rem, 1:8″ Twist
.22-250 Rem, 1:8″ Twist
.243 Win, 1:8″ Twist
6.5 Creedmoor, 1:8″ Twist
6.5×284, 1:8″ Twist

280 Ackley, 1:9″ Twist
7mm Rem Mag, 1:9″ Twist
.308 Win Match, 1:10″ Twist
.300 Win Mag, 1:9.4″ Twist

Slow-Motion Video Shows Bullets Pass Through Muzzle Brakes

Proof Research High speed photography muzzle brakeIf you want to see how a muzzle brake really works, definitely watch this remarkable slow-motion video compiled by Proof Research.

This amazing video features a variety of firearms: suppressed 9mm pistol, .338 Norma rifle, .300 WinMag rifle, 12ga comp’d shotgun, plus an AR15 and AR10.

This Must-Watch Video Has Some Amazing Ultra-Slow-Motion Segments

Watch the ultra-slow motion segment at the 2:55 mark and you can actually see a .30-cal bullet spin its way through the muzzle brake, leaving trail of flame that blows out the ports. Interestingly, at the 3:10 mark, you can also see a bright “afterburn” ball of fire that forms a few inches ahead of the muzzle milliseconds after the bullet has left the barrel. Perhaps this is late ignition of unburned powder?
