Berger seating depth.

I'm working up some loads for my 28 Nosler in 140 gr VLD Hunters with Winchester StaBALL HD starting at 75.5 gr and working up to 86.5 gr. So far only 2 loads are at sub moa at 100 yds but at 200 they open up over an acceptable amount. Does seating depth effect Berger bullets unlike Hammers?

Yes VLD are sensitive to seating depth. Run the Berger seating depth test. It is on their website. Personally I would run a heavier hybrid in the 28 Nosler mine loves the 175s and 195s.

140 HVLD in a 28 Nosler? 3600fps+?
Laser beam speeds!

That doesn't sound conducive to easy tuning or accuracy in general. But yeah, test seating depths if you're dead set on that combo for some reason. I would move up to at least 175gr. In that cartridge if you're shooting lead though.

According to Steve, Hammer bullets are not AS sensitive to seating depths as Berger's. As mentioned, use the Berger recommended seating depth process which should get you where you want to be Or try different projectile or powder. Remember, don't force feed the barrel if it doesn't like that combo.

Thank you. I have 175s for elk but bought these 140s for deer.

I can't thank you guys enough for the information. I just went on their site and now have a good idea how to proceed. I've already tried 50 rounds with 10 different powder loads and now hopefully I'll be a lot closer to tightening up the groups.

They like an ideal jump off the lands in the .030-.040" range.

X3 Every VLD I've ever shot has wanted at least .030".

 

[timblevins]

Okay that explains a lot. I'm only .020 off right now.

 

[cb4128]

I've shot them from .006 off to .090 off and it's all gun dependent.

That being said, I usually start out at .040 off for hybrids and .020 off for VLD or Elite Hunters

Not to mention shot out after break in

Of course the bullet will unravel 50' in front of the muzzle also cause im sure it's a 8 twist

That's not at all what that link says. They say there's a .030-.040" wide window that gives good performance, but that window could be anywhere from a slight jam to .150 off the lands.

In my experience with Berger VLD hunting bullets what's written on their website is pretty accurate. I have found it to be accurate for every other secant ogive bullet I've tried too.
