help with heavy 22 grendel load data

[Saltydoge]

I read your post 3 times because I felt like I was missing something.

When you say “GRT”, can you provide more reference to what that source is? How did they determine their pressure readings?

.224 AR has been a wildcat that Robert Whitley has been offering complete uppers and load data for during the past 13 years.



Here’s a PDF of some of the load testing he did.

I would use his start loads and then work up some pressure ladders in .2gr increments to get an idea of how it builds pressure/velocity relative to charge weight increases.

sure thing. I put enough text to rival the average text from the wife and I got lazy. GRT would be Gordons Reloading Tool. Its a handy software, a free version of quick load and all community driven.
I took Mr. Whitleys data. Man some of that stuff is HOT but if he is running 27gr of powder on an berger 82gr with varget and recommending it. I think that GRT is not giving me a nonsense number. Guess ill have to rebuild the bench and get going on the weekend. Thanks for the help.
