How could or should the 6.5 mm Grendel be improved?

[woohoo]

Would the improvements in performance over the Grendel really be worth the additional weight?

I think our best bet here is to get a LMG built to accommodate the Grendel and see what kind of attention that attracts.

Then if we can get a steel core FMJ bullet developed, so we can prove our assumptions.

Stan, answered you on some of this. It takes a class 10 ammo manufacturer to produce steel core bullets then it can only be sold to govt agencies. Only a #7 with a type 2 stamp can manufacture LMGs. They can be designed and tested but only sold to govt agencies after approval.

Just last week I received 2 new 25round Grendel mags. Knowing already about stacking/ swelling problems I checked them out by loading rounds in the mag. The tops of the cartridges do not touch the bottoms of the cartridges above. That causes the mags to swell but the mags create pressure on the cartridges in the mag. That needs to be addressed.
The increased bolt strength adds no weight to the system.
He asked "what could be done to help military and LE users accept and use the 6.5 mm Grendel more widely?"...Well that's just my opinion on how to improve the system.
