Home Forums Hunting & Shooting Ask The Gunwriters Re-thinking bullet jump article

A lot depends on how your rifle is throated. In the article they are shooting precision rifles with tight throats. That helps with alignment.

Factory chamber throats can be ( but not always ) on the loose side. I find getting to the lands helps accuracy. Newer chamberings are spec’d with tight throats and are more jump tolerant. This helps accuracy all around and is why new chamberings tend to shoot really well.

Some rifle manufacturers are catching on and chambering their rifles with more attention to how tight the throat is.

Rifles with long tight throats are also less susceptible to eccentric ammunition. With less than .001” clearance , it’s hard to start a bullet really crooked.

Good accuracy smiths know all of this and subsequently spec their reamers for proper throat clearance. This is one critical aspect to getting older chamberings to shoot tiny groups.
