Dwh7271 thank you very much.

Bill

 

[Dwh7271]

Anytime

 

[SJB358]

Are you going to give them a shot Bill?

Are you going to give them a shot Bill?

Well I'm going out in the am to see if I can get them to shoot, if they do, I intend to give them a go this season for deer. But I if have a change of heart with the VLD's I do have my AccuBond load shooting well out to 500 yards.

How did you do at 500 with the ABs.

 

[OU812]

Scotty it started out like this. I had 6 rounds of twice fired brass and 9 rounds of 4 times fired brass all of the exact same charge, primers, bullets, trim length, full length resized. I fired 6 rounds of the 4 times fired brass at 400 yards and it sucked, 2 MOA group. Put a target up at 100 and shot a 2 MOA group. I was pizzed to say the least. Decided to try my 2 times fired brass and shot the smallest group yet, slightly over 1/2 MOA, normally it's 1 MOA. With my last 3 rounds I did what is below.

I didn't shoot at 500 for group size I shot at 2, 1 gallon water filled milk jugs. I fired 3 shots as that is all I had left. First shot I missed the call on the wind and hit to the right of the jug. Next 2 shots I corrected for the wind and hit dead center elevation but 3 inches to the right of center and the 3rd shot was again dead center elevation but 2 inch and some change to the left of center.

I will be back out to shoot for group size at 500 and 600 yards but not with brass fired more than 3 times with out annealing that's for sure.

 

[SJB358]

I'm pretty sure it was either the 264 or 270WSM that got me started annealing just for the reason you just mentioned.

Glad your drilling stuff with them though. I like the 140 AB in mine a lot.

I had the issues years back with my 338 Lapua until Rick S got me straightened out on the need for annealing. Work harden brass will screw up groups quick fast and in a hurry that's for sure.

I really like the 140 AB but am curious to see what a VLD will do.

 

[SJB358]

I've gotten into the habit of annealing every time since keeping track of a bunch of different cartridges was too much. Since I've started annealing each time I feel like brass life and my overall consistency has gone through the roof.

 

[OU812]

I need to be more diligent on annealing that is for sure.
