no pressure. As usual I started too low with Hammers again..
How many rounds per charge weight interval? It looks like 1? Heres the problem. If youre not interested in reading the whole article, scroll down to the last page, 13, and look at the graph! I was a Satterlee believer until I saw this! Just saying .

Also, little heads up! The cci 400 are thinner cupped primers, designed for bolt action rifle! And not recommended in semi-auto AR-15 style firearm because they increase the likelihood of slam fires!
Did you run the new, unfired brass through a neck sizing mandrel before loading? Factory brass has wildly different neck tension! Without neck tension uniformity, respectfully, your observed data is suspect! For the record, I made that mistake for years!
The Grendel is a great, versatile hunting choice, trying to save you from making the same mistakes I did! Lord knows, Ive made them all but still try not to make the same mistake more than 3 times in a row! At least, thats my current goal!
