Just ordered a NOE 264 mould to try in my 260 Remington Striker. I have lots of gas checks for .270 and was wondering if anyone tried to use .270 checks for .264 bullets. I will be sizing to .265 so only 12 thousands difference. I use a check seater for my Lyman lubrisizer so should be able to seat checks square to bullet. Will be casting with straight linotype so will have good hard bullets too. Seems a shame not to use all these .270 checks. Thanks for any info or tips.
