Hi guys, I recently built a 22-250AI, 8 twist barrel and I'm planning to shoot the 75g berger vld's in it.
I have never shot any VLD bullets before. I came across an article on Berger website of them talking about the VLD and how they couldn't get them to shoot well or group, and then they figured out those bullets like to be EITHER jammed in the lands OR stuck deep into the case for a long jump.
Any help would be great, as I don't want to be wasting ammo in the desert. I guess my question is what do there bullets like for seating depth/ jump?
Should I try the .010", .020", .030", .040" off the lands and so on for groupings test? Or will I be wasting time and just need to go right to .090 + of a jump? Berger says to try .010", .050", 0.90", .130" off the lands, is this an old post???
Again any insight would be helpful on the VLD's
Thanks

VLD's don't like to jump. I would measure them jammed, subtract .003" for insurance, the seat 5 rounds at .030" etc... if you find a load with them nice and close to the lands or longer from the lands.. go with the closer to the lands, as that hot 22-250 wears the barrel throat you know you can start to seat the bullets farther out . Make sense?

my wife thinks I only have 3 guns

Makes perfect sense yes.
I have my lands measurement for those bullets already. So I'll start with what you stated, and go on from there. Thanks for your help. I definitely prefer hearing that they don't like to jump over they do like to jump !

Not in a 22-250A1, but using 75 VLDs in 223 for high power competition. This is the standard seating depth used adopted by military teams and lots of civilians - jump from 0.030 to 0.040. This load is for the prone slow fire, single loading.

Here is an example of first 5 shots out of the barrel after boresighting, 0.035 jump, 75 VLD. 200 yards, 20 inch barrel 4.5X scope, prone, sling. PoA is the center X on the NRA SR target.

The 210 and 190 vld’s out of my .30 Cals always shot best from touching to .005 off.

Awesome, I'll try that seating depth jump range as well !

Did you ever try .020"-.060" off to see if those would group as well? Or did you hit a quick home run at touching and .005" off and called it quits?

I did try at many different coal’s from 3 different rum’s. From about 3.6” to about 3.9” and best groups were always within .005 off.

OP,

If you want to run magasine fed ammo, and run real fast, grab some Berger 70 VLD. These little pills will run from magasine with no drama. A couple of our top service rifle shooters in the TX run these and shooting knots in the rapid fire events at 200 and 300 yards.

When I was testing these I ran them through different freebore length from 0.025, 0.062, 0.084, 094, 0.1, 0.140, 0.170 and they shot jumping from 2.250 COL in AR mags. I have a zero freebore reamer, but did not test them in that chamber. The 0.170 is what I chamber with to run the 90s for 1000 yards prone matches.

I guess I need more help from you guys. As for when I tested the lands measurement in my rifle with the berger 75g 22 caliber with my modified case there is only .171" bullet inside the bearing surface which visually doesn't look like enough bullet grab to my eyes?
The VLD having a secant ogive really doesn't have that long of a bearing surface.
I've always heard to have the bullet inside the neck at least the same amount as the bullet diameter (which doesn't include the boat tail area). So in my gun it would be .224"?? The berger 75g 22 caliber bearing surface is .291" long.
That being said that would give me a .067" window for seating adjustments to have that (diameter of the bullet inside the case neck)
OR is .171" inside the neck enough bullet grip for shooting them on the lands measurement, or near the lands measurement. If I needed .224" of bullet grip inside the neck that would give me a starting measurement of .053" jump off the lands just to start.
I'm use to shooting/loading hybrid bullets that have a longer bearing surface.

I've read the same thing but run your test seating to where you like. Trust me the gun will tell you if it likes it or not. I have some loads for my 270 and the bullet looks questionable rather there is enough in the neck but I'm getting 1/2 inch groups with the load.

Can anyone answer about how much bullet length (bearing surface) should be inside the neck of a case?

I once heard an old "rule of thumb" of like 50% of the bullet dia. But for hunting rounds I like at least .200" It just all depends on how careful you want to be with the ammo.

I was hoping you would jump in on this. Glad you did thanks Jeff. I’m going to roll with your advice. Again it’s a hunting rifle for varmit hunts. So likely the ammo won’t be handled with the outmost careful procedures by any means. I’m going to start shooting the gun this weekend. Can’t wait to see what it can do! Thanks everyone for the advice

I just re-barreled my 25-06. During break in, I shot about 15 old Berger 115 VLDs I had. Seated them .020 off the lands. Five shot group was around .6 MOA. The powder charge was relatively mild as well. I'm trying to get this gun to shoot the Hornady ELD-X right now, so I never tuned the Berger load.

I've never found vld to like living the Iands exclusively. Berger has found the vld to like a specfic depth anywhere from 10k off to up to 150k off. Usually the window found will be quite wide thay the bullet shoots well in. I've found that seating depth nodes closer than 30k are far more sensitive and smaller than depths further off the lands. Here's bergers recommendations attached. I have several thousand 135 and 140 jlk vld 6.5mm bullets coming for the creed and saum, they're old school vld but had better bc than the bergers and have a great reputation for killing.

I know it's not Berger VLD, but the ELD-X bullets I'm shooting are grouping well at .060 off the lands. I'm gonna test .050, .040, .030 next. When I first started seating depth testing with these bullets I made .030 jumps all the way to .110 off. The last test I shot was coming out of the case from .110 jump, and .060 won. That might we'll my sweet spot, but I'm gonna make sure with three more seating depths.

Friendly Update.
My 22-250AI fell in love with the berger VLD 75g @ .075" off the lands.
My seating depth window was actually pretty solid from .075" off - out to .095" off
Hope this might help people in the future.

One of my rifles likes a .010 jump and another .030 with VLDH Bergers.
