a while back berger put out a notice about vld's, accuracy and long jumping. has anyone in 1000/600 yd had a chance to evaluate the idea ?
thanks

I tested all the way to .120 off the lands and found my best groups to be .010 to .015 off as far as jumping goes. I have found that .005 in the lands to be my best.

I did the test out to 0.12 but find having the bullet in the rifling to be best for the 105gr 6mm hunting VLD. I talked to Berger and they suggest you retest as your barrel age since the VLDs are sensitive to setback.

Lynn,
That sort of makes the Freebore Measurement mute (refer to the BRX thread), don't it! I've got a Dasher with a .104" FB set up for the 105 Berger VLD, but the damn thang will not shoot the 105. I am shooting 108 BIBs at .005" Jam and they will shoot. It also likes the 107 SMK setting at .010" jam! About .020 Jump is all that my Neil Jones Hand Seater will give me before it bottoms out!

go in 0.040 increments from your maximum jam length.You can seat a 105 berger around 0.125 into the lands with enough neck tension so it would take 3 seperate groups of bullets just to be at the lands if you used 0.040 increments.If your die doesn't want to go there buy a cheap used Wilson die without the micrometer top that is rusty and simply run your reamer into it using your trusty black and decker and you get instant 6Dasher seater.
We have guys out here jumping Bergers 0.185 so you will need atleast 7 or 8 groups of bullets to achieve that much range.
On that other post the guy has had his standard of the industry design for less than 2 months yet he wantds me to believe HIS design is the cats a$$.What he means to say is I am using what everybody else is using after having two reamers built my waty that didn't work as well as everybody elses.You then have a Supermoderator sitting on his thumbs instead of making him correct his post so it only gets worse.

This was in accurateshooter.com a month ago. Note Sam jumped his .040". I always jam VLD's, but intend to experiment with jumping in my new Dasher barrel.

Hall Breaks IBS Records with 0.686″ (50 pt.) Group at 600 Yards
On June 12, 2010, at the Piedmont Range in Rutherfordton, NC, Sam Hall, shooting a 6mm Dasher, set TWO new pending IBS 600-yard world records with a stunning 0.686″ five-shot group. The group was centered up in the Ten Ring for 50 points with two doubles! This group should give Sam both the single target IBS Light Gun small group record AND the Light Gun score record. Sam’s 0.686″ beats Paul Wagoner’s 0.711″ previous small-group record set in 2008 with a 6 BRX. Larry Isenhour previously held the IBS score record with a 50-3X (0.944″) group shot in August, 2007, also with a 6 BRX. NOTE: Sam had only one X, but the official tie-breaker for the score record is group size, not X-count. Therefore, if approved, Sam’s 0.686″ group establishes both new group size and score records. (We wish the IBS had some other official recognition for high X-count.)
Record-Setting Chambering, Load, and Hardware
Sam was shooting a 6mm Dasher with 32.0 grains of Norma 203B powder, Berger 105gr VLD bullets (unpointed), CCI 450 primers and Lapua brass, neck turned to 0.266″ for a 0.268″-necked chamber. Regarding the choice of powder, Sam says Reloder 15 gives the same accuracy and speed as 203B but he “just happed to have 8 pounds of [203B] and decided to use it in this rifle.” Interestingly, Sam was jumping his 105s about forty thousandths. That’s right, .040″ OFF the lands. The record gun has a BAT MB action, Shehane Tracker stock, and Krieger 29″, .237″ bore, 1:8″ twist HV barrel.
Last year, I could not get the Berger 105 VLDs to shoot like I wanted in this barrel, so I used Berger 108 BTs, jumped .015″. After last season, I tried the 105 VLDs again. I think they have a slight advantage in the wind compared to the 108s. But again the 105s would not shoot well at 600 jammed in the rifling as I normally do. I noticed this barrel was shooting better off the rifling. I kept backing the bullets off the rifling. I found a sweet spot 40 thousandths off the rifling. The gun was shooting 1 to 1.5 inch groups pretty consistently at 600 yards at my home range. The day I shot the record was the first time I had shot this load and rifle in competition. I believe it is a keeper! — Sam Hall
