You just answered your own question. Drill it to fit the VLD bullets. No tip contact.
No, actually he didn't. I'm measuring a 6.5 Creedmoor stem and the diameter of the stem is the same size as the bullet itself, .264". I'm not entirely sure if that is the case with all calipers, but suspect it might be. That's kinda similar to a 1/4-20 machine screw.

Many times, you can make this fix yourself through the use of a drill press. Secure the seating plug under a 3/32" bit and drill further into it. The distance should never be increased more than 1/4". If this does not solve the issue, we recommend sending it to us.
This sure makes it sound easy, but I don't know how much metalworking you folks do, and you're probably better than me, but those stems are not drilled with a drill bit, or even the proper angle countersink, AFAIK. They look like the throat is ground and polished. Do you need that level of finish? I think you do if you care about your bullet tips. The bottom line is most of us are just looking to reload without marring the bullet behind the actual tip so aerodynamics of the bullet are not effected.
I do have a fair amount of machinery and tooling, but don't have a cylindrical grinder. I could use my toolpost grinder on my lathe, but I have to weigh the cost of the stem ($25-$30) and start to calculate how much my time is worth to me, and I concluded it was much easier and safer to buy one that Redding manufactured. If you can hold it in a drill vise and perform the task to get your bullets seated in a small amount of time, more power to you.
I recently received an RCBS micrometer die with both stems in the box. The same 6.5 Creedmoor cartridge, and the stem throats are slightly different between RCBS and Redding. So, like everything else the Redding stems might not even fit your bullets perfectly. But if you're using common VLD bullets, in theory they should. All of our mileage varies...and I really haven't done too much testing. I suggest people interested in precision reloading just buy the VLD stem...my $0.02...(worth what you paid for it).
EDIT: I have also heard about die makers who will grind and polish the stem for a specific bullet nose cone, ultimately that would probably be the best if precision is the main concern. What are your expectations?
