In this video Bryan Litz of Applied Ballistics offers tips on Big Bore shooting (i.e. .338 caliber and above). Bryan offers advice on bullet selection and he explains the challenge of handling the blast, noise, concussion, and recoil of big boomers such as the .416 Barrett and .50 BMG.

Bryan goes big … very big, shooting a monster .50 BMG bullpup.

Big Bore Basics — Tips for Shooting Big Boomers by Bryan Litz
There are some unique things to consider with big-bore shooting. One is bullet design. For long-range shooting you want high-BC bullets. You get high BC from heavy bullets and bullets that have low drag. The interesting trade-off in big calibers is that there are a lot more lathe-turned solid bullets in copper and brass available than there are in the smaller calibers. You’ve got bullets that have slightly lower drag profiles but they are made of materials that are slightly less dense (than lead) so they are relatively light for their caliber. With that trade-off, the BCs might not be as high as you think for big calibers, although the bullets are heavy enough that they carry a lot of energy.

Energy really has a lot to do with shooting these big-caliber rifles. As with any kind of shooting, the fundamentals of marksmanship are the most important thing. However, it can be hard to maintain good fundamentals (e.g. trigger control and sight alignment) when you’re burning 100 grains of powder. There’s a lot of concussion (you want a muzzle brake no matter what your cartridge is above .338). It certainly can be challenging with all the muzzle blast and all the energy coming out of the barrel.

For long-range shooting with big bore rifles, you are still looking for the same things that you want with smaller-caliber rigs. You want a high-performance bullet, you want consistent ammunition, and you want a good fire solution to be able to center your group at long range. Basically you’re just dealing with the challenges that the high energy brings, and being smart about your bullet selection.

In the video above, Bryan is shooting the DesertTech HTI bullpup. This rifle can shoot four (4) big bore chamberings, with barrel conversion kits for: .375 CheyTac, .408 CheyTac, .416 Barrett, and .50 BMG. These can be quickly swapped in the HTI chassis, which employs an internal barrel-clamp system.

San Francisco’s Last Gun Store Closes — Thanks to the Politicians

This is a cautionary tale of what can happen when municipal governments are allowed to enact radical, restrictive gun laws…

San Francisco, California has over 850,000 residents*. But thanks to SF’s gun-phobic elected officials, you soon won’t be able to find a single store that sells guns and ammo within city limits. High Bridge Arms, San Francisco’s last remaining gun shop, announced it will be closing its doors in October. The reason is the threat of a new SF law requiring gun retailers to video-tape sales transactions and turn over private customer data to the city. This proposed city ordinance goes way beyond existing state and Federal background check requirements.

“Big Brother” is alive and well in the “city by the Bay”. According to Guns.com, San Francisco Supervisor Ken Farrell introduced a municipal ordinance requiring gun vendors to video-tape gun/ammo sales transactions and deliver buyer/firearms data to police every week. Gun shop owners would be required to “hand over personal information to include names, addresses and birth dates to city officials in conjunction with gun and ammo sales.”

Given the threat of this draconian new city law, High Bridge Arms, San Francisco’s last remaining gun store, announced it would cease operations next month. Posting on Facebook, High Bridge’s owner declared: “We are closing our shop. For many reasons I cannot get into at this moment, it appears our final days will be through to the end of October of 2015.” It is not known whether High Bridge Arms will re-locate to a different location outside San Francisco city limits.

San Francisco-based Top Shot Champion Chris Cheng says the closure of High Bridge Arms will only encourage the anti-gun politicians who run the city: “With High Bridge moving out, it will be interesting to see what will happen to legislation the San Francisco Board of Supervisors is considering which would require video-taping gun and ammunition sales, and sharing ammo sales data with SFPD. My guess is that even with High Bridge closing by the time they vote on this, they will pass it in the hopes to keep any future gun shops from trying to open in the future.”

High Bridge Arms has a long history in San Francisco. Serving sport shooters as well as city law enforcement personnel, High Bridge has operated in the same Mission Street location since the mid-1950s when Olympic shooter and gunsmith Bob Chow opened the shop. In 1988, Andy Takahashi bought the business from Mr. Chow.
