I agree. The reason I did not suggest gel tests is because very few, if any, members have the ability (or desire) to work with gelatin. I wanted to keep things as simple as possible.
Quote:The only other suggestion would be to use a better grade of factory ammo for the Grendel than Wolf. Wolf ammo is well known for being fairly inaccurate, and that wouldn't help the results. Hornady, Alexander Arms, or Black Hills ammo would provide more consistent accuracy. I'm not suggesting using match ammo for the Grendel and ball for the other cartridges as that wouldn't be fair. However, using ammo that is pretty well known for the worst accuracy of factory ammo isn't fair either.The trouble is, Hornady, AA and BH make premium 6.5 hunting and target ammo. They do not make 6.5 FMJ, or ammo that is representative of service grade ball in terms of accuracy.
I specified Wolf because (from what I recall posted by LR1955 on the old forum) the MPT is comparable to standard military ball in regard to accuracy, and the pending FMJ is the same bullet type.
However, a possible answer to your "fairness" objection would be to use ammo with TSX bullets for the infantry rifle and machine gun tests. That should provide the same degree of accuracy in each caliber for the infantry rifle test, and give representative penetration of each caliber in the machine gun tests. In factory ammo, Black Hills makes 62gr 5.56 TSX, AA has 120gr 6.5 TSX, and Federal offers 150gr 7.62 TSX. Would that be satisfactory?
