I am reloading 338 lap for a remy mlr. Wilson dies on an arbor press. Size die with .365 bushing works well, although requires more effort than with other calibers, then when I put the primed case in the seat die, the case wont seat completely. Any help or suggestions appreciated.
Lapua Brass fireformed in rifle then tumbled and prepped
Dies are clean
Hornady 1 shot lube used liberally

Re: 338 lapua reloading problems

You did not mention if you are full length sizing or neck only.

If you are full length sizing and bumping the shoulders back close to .002" you may have a die problem.

If you are neck sizing only, you have a sizing problem and need to bump the shoulders.

Good luck.
