Impressive Accuracy with 6mmBR Tubegun and Bergers
Just how accurate can a 6BR Tubegun be, when shot from the bench with bag-riding attachments? Would you believe 0.170 MOA at 200 yards? Yep, that’s benchrest-grade accuracy out of an across-the-course rifle.
Forum member Milan recently tested his new Eliseo R5 6BR tubegun with Berger 80gr Varmint bullets. We’ve found the Berger 80s to be extraordinarily accurate, and Milan confirmed that fact. His R5 features a Krieger barrel, Pierce action, and Jewell trigger. At right is his first 5-shot group, with the size calculated with On-Target software. The calculated group size is 0.355″, or 0.170 MOA at 200 yards. (Measured by Milan with calipers, it was slightly smaller, 0.350″.)
Milan reports: “Today, I took my brand new R5 rifle (stock made by Gary Eliseo with Pierce Engineering Action and gunsmithing, and Krieger barrel) to a shooting range for the first time. I was shooting at 200 yards and my very first shot was on target. I shot one more time in the same spot and cleaned my rifle. I shot another three shots to find the center of the target. I cleaned the rifle again and shot my first 5-shot group. Looking through my scope, it all looked like one hole. I got a big smile on my face and could not get any happier. When I got home and measured the group, it measured less than 0.350″. Bummer… I was looking forward to the challenge of finding a good load for this rifle but it seems like now I will have to look for another challenge. My load was Berger 80gr Varmint Bullets, 31.0 grains of Varget, Remington 6.5 primer, and bullet was seated 0.015″ in lands.”
Milan added: “The silver rear bag rider attachment came from CSS. I only modified it a little. I lowered my rifle about 1″. I also made my own design, shown below, which allows me to make fine height adjustment on my rear bag when shooting from a bipod and to keep the front of my rifle as low as possible. I would like to thank to Gary Eliseo and John Pierce (Pierce Engineering) for a great job. I highly recommend the services of both these guys.”
