Home Forums Hunting & Shooting Custom Rifles & Wildcats New custom rifle won't chamber some cartridges

McInnis,

Often if your seating (NOT sizing) dies is down to far you can expand the shoulder or even crush it so it won’t chamber.

The sizing die will push it back, the seater however will jack it up...

So re-size those and make sure the seating die isn’t touching the shoulder and then see if they chamber.
