and Yes mine is loaded to 45.5 it has never shown any signs of pressure chronographs at 2740 with a 24 inch barrel no primer pockets loosening up no sneakies stuff yet no stiff bolts nothing GRT got this one wrong I really believe.
I wonder if they're actually using bullet data for the original x bullet

It seems that there are few data sources that give the same top end loads.

Like the OP I've reloaded for decades. These software programs (GRT and QL) intrigue me.

Can anyone recommend any good tutorials either youtube videos, books, websites to learn:
1) how to use them.
2) what parameters I should be looking at.
3) what the values should be for those parameters.
and
4) what other questions I should be asking?

Feedback appreciated THANKS
