You gentlemen that were discussing the 311-247 FN CONVENTIONAL LUBE GROOVES being used in the 300 Blackout pistol in July of 2019 might want to think about getting together with the new thread topic TL310-225-RN-CE3 in July of 2020.
In that new topic there is a fellow shooter who is currently looking for some load data for his 300 Blackout pistol with a similar heavy cast bullet weight.
Since both threads are to be used for the 300 Blackout pistol, & the cast bullet weights are similar, You both might benefit from the sharing of your mutually accrued load data intel.
Maybe also then we can restart up the forum strings once again to share intel on the loads that we have all individually come up with over the past year or so.
Take Care & Stay Safe.
