Tubb T7T Two-Stage Trigger for Remington-Type Actions

David Tubb two-stage 2-stage T7T trigger Rem 700 Remington clone high power

You probably know by now that David Tubb has introduced a new two-stage trigger for Remington 700 rifles, the Model T7T. Priced at $385.00, the new T7T Trigger is a true two-stage design: first and second stages are independently adjustable for both weight and feel. Overall (combined stage) trigger pull weight can be adjusted from just under 1 pound to slightly over 3.5 pounds.

If you are interested in the 7ZT, watch these two videos. The first shows how to adjust pull-weights for both stages. The second video shows how to modify your stock to provide clearance for the T7T.

This video shows how to adjust the new Tubb T7T two-stage trigger for Remington 700s:

The new T7T is a quality product. We’ve received good feedback from “early adopters” who tell us the two-stage function works well. While installation of the T7T may require minor modifications to your action, most gun owners with basic mechanical skills can install the T7T by themselves. The T7T is made using stainless steel and aluminum for maximum corrosion resistance. Note, installation of the T7T trigger (either Right-Hand or Left-Hand) also requires a companion T7T bolt release, offered by DavidTubb.com for $10.00.

Mid-Sized 6mm Cartridges — Great Accuracy & More Zip than 6BR

Many precision-oriented shooters are discovering that the “middle ground” in cartridge size is optimal for the 100gr to 115gr match bullets. With a mid-sized cartridge, you can run these pills faster than a 6BR or Dasher, without giving up much, if any, accuracy to a 6BR or BR Improved. The most accurate 600-yard rifle at this Editor’s local club is a 6-6.5×47. It can shoot as tight as a 6BR past 300 yards, plus it offers better ballistics, pushing 105 Bergers at 3140 fps.

If you’re considering a mid-sized 6mm cartridge for your next rifle, you’re probably wondering WHICH mid-size 6mm cartridge is best. We are often asked “what’s the difference between the 6×47 Swiss Match, the 6XC, and the 6.5×47 Lapua necked down to 6mm?” All three cartridges have 30° shoulders and fit a .308-sized boltface. However, alone among the three, the 6mm-6.5×47 has a small primer pocket and small flash hole. The 6×47 Swiss Match (made by RUAG), and the 6XC (produced by Norma), have a large primer pocket and large flash hole, just like a .308 Winchester.

Forum member DesertLefty has provided a line-up photo, with 6mmBR and .260 Rem cases provided for comparison. As you can see, the three mid-sized cases (6x47SM, 6.5×47 Lapua, and 6XC) are very similar. The Swiss Match has the longest neck, while the 6XC enjoys the highest capacity. But performance is very similar among the three cartridges (with the 6.5×47 necked down to 6mm). The same powders, (particularly H4350, Reloder 17, and IMR 4007SSC) work well in the 6×47 SM, the 6XC, and the 6-6.5×47 Lapua. The parent 6.5×47 Lapua case is rated at 63090 psi, while the new CIP rating for the 6XC is 63844 psi (4400 BAR). Both the necked-down Lapua brass and the Norma-brand 6XC brass can hold stout loads. Though the 6mm-6.5×47 has slightly less powder capacity than the 6XC, max velocities with 105-108gr bullets are quite similar. However, you should not substitute loads from the 6XC directly to the 6mm-6.5×47 or vice-versa. Because of the different case capacities and primer sizes, you should work up loads separately for each cartridge.

Tubb Instructional DVD Can Benefit Position Shooters

David Tubb’s instructional DVD, “The Art & Technique of the Modern Match Rifle”, is a great resource for any High Power or position shooter. This 2-disc DVD provides over 4.5 hours of instruction and shooting demonstrations. We’ve watched the entire video and can assure you that it is excellent. Novice High Power and prone shooters who apply David’s methods should definitely improve their scores.

David has included highlights from that DVD in a shorter promo video. While the shorter video is a sales tool, it’s very informative in its own right. Watch the video and you’ll learn a great deal just by watching how David shoulders his rifle, and how he adjusts and maintains his shooting position. David shows examples of prone, sitting, and standing positions. In the short “trailer”, David also provides helpful tips on adjusting sights, and placing the spotting scope.

If you shoot Service Rifle, High Power, or prone, you can benefit from watching this short sampler video. The full 2-disc DVD is available for $49.95 from Creedmoor Sports or Superior Shooting Systems. With over 4.5 hours of content, the DVD covers all the across-the-course positions, the set-up and use of aperture sights and diopters, High Power and long range targets, the approach method in offhand, proper placement and use of spotting scopes. The DVD includes bonus footage of David shooting strings in all of the across-the-course positions.

Houle Wins His Third National High Power Championship — Bernosky and Tubb Close Behind

Norman Houle National Champion 2009Norman Houle of West Warwick, Rhode Island, is the 2009 NRA National High Power Champion. Congrats to Norm! His come-from-behind, one-point victory marked his third High Power National Championship. His previous wins coming in 2004 and 2006, Norman was unable to shoot in last year’s competition.

The National Champion is the person with the highest aggregate of scores fired in the Vandenberg Cup, Nevada Trophy and Clarke Trophy Matches, and they receive the Mumma Trophy, a footed sterling silver urn with an ornate top, side handles and spout.

Houle scored 2387-124X, just one point more than last year’s champion Carl Bernosky (2386-125X). David Tubb finished third with 2385-133X. This year was the closest point differential Norman could recall. High Woman Shooter, and the early leader in the competition, was SPC Sherri Gallagher. Sherri, who finished with a 2382-148X score, has the highest X-Count total among all competitors — by a wide margin.

Norman Houle National Champion 2009Houle, Tubb, and Gallagher are all teammates, along with Ronald Zerr, on Team Creedmoor, coached by Dennis DeMille of Creedmoor Sports. Team Creedmoor won the 2009 RNDC Team match, one of four team events that is part of the championships. Two other events, The Enlisted Men’s Trophy (for military teams of four firing members) and The Rumbold Trophy (for civilian teams whose members belong to the same club or state association), are fired concurrent with the RNDC. The fourth event, The Whistler Boy Trophy (for teams of two, junior-category firing members who represent a state association), is fired during a separate day of competition.

In other Camp Perry Results, SFC Grant Singley (2385-102X) won the NRA National Service Rifle Championship, convincingly over USAMU teammate SGT Brandon Green (2370-90X). Dennis DeMille was High Civilian, posting a 2359-99X. Though she missed out on the big prize, SPC Sherri Gallagher won the Army Cup Match, the Crowell Trophy Match, the Centenary Trophy (Agg), and the Vandenburg Cup. Her 800-53X score in the Vandenburg Cup broke a National Record.
