My only fear with them is having to stuff the bullet deep into the case to make mag feed. With the mag limiting me to 3.4'' I don't think I'll be able to get the VLD bullet close to the rifling and mag feed the gun. I've never shot a VLD that didn't want to be jammed onto the lands or seated right next to them. The LRAB quite were jump tolerant in the last barrel.
I have one rifle that shoots with them 60 thou off but yes I find most don't. What I do when I have something chambered is make up a dummy round with a vld that fits the mag and has enough of the bearing surface in the neck and then ask to have it throated so that dummy round is 10 thou off. I give up a little speed as you'll likely hit pressures earlier with out factory freebore but it's more than made up for with accuracy.
I haven't measured any lrab's but other nosler bullets that I weighed and measured the bearing surface on weren't consistent enough to get the long range accuracy I was looking when building something like you did.
