Weatherby's purposefully seat way off the lands. It helps if you are trying to maximize velocity.

If you are reloading learn the optimum charge weight method. I have found that distance from the lands does not make a lot of difference once you find the optimum charge weight for your bullet/brass/primer/powder/rifle combination.

Freebore is bad. I have found almost universally that accuracy is better with minimal freebore. Most of my taylored loads end up within 0.020".

The effect of freebore vary with bullet, load and ammo quality. With a standard bullet style (not a VLD) and ammo with very good to excellent concentricity and very low bullet runout, freebore isn't as big an issue. With VLDs the bullet tends to yaw in the freebore and enter the rifling sideways. Rounds with a lot of runout will do the same thing. Jamming the bullet into the lands or at least minimizing effective freebore can reduce the effects.

I haven't a clue what the issue is?

Sorry, Original post was not sent in it's entirety; here it is; I have 22-250 that like bullets seated .050 off the lands. I have loaded several accurate rifles over the years, but have always started at the lands and usually within
.015 is where I have found best accuracy. I tried .050 on a tip after I was about to rebarrel it. It is cured now, it just likes lots of jump. I have never had this happen before. It shoots one hole groups now, I just returned from the range, trying some different powders and it seems the rifle likes the bullet off the lands, not a different bullet, or powder or velocity.

There is plenty of factory match ammo that shoots great and jumps more than .050 in most guns.

Well, seems you found the answer to your question. ??

And some rifles like twice that much jump.

There is a recent Rifle magazine and in one article the author compares the bullet jump of a number of 7mm cartridges, some skip a country mile due to throating.

On some pre 64 257 Roberts, owners removed the magazine block so they could seat the bullets long enough for the throat.

There is a lot of jump from my LR308. It still shoots 1 MOA. I realize this is not the best accuracy but plenty sufficient for me.
