22-243 load development?

[zr600]

Ok I'm gonna go be shooting my 22-243 real soon. My first load is going to be rl17 with 75g amax lapua cases and federal primers were should I start on powder charge?

[sharpshooter]

Start at the same point you would with a 75 gr. .243 bullet.

[Zero333]

According to Quickload... 40 to 41 gr of RL-17 is MAX with the 75gr Amax in the 22-243.

Predicted Data for Indicated Charges of the Following Powders.
Matching Maximum Pressure: 63000 psi, or 434 MPa
or a maximum loading ratio or filling of 108 %
These calculations refer to your specified settings in QuickLOAD 'Cartridge Dimensions' window.
C A U T I O N : any load listed can result in a powder charge that falls below minimum suggested
loads or exceeds maximum suggested loads as presented in current handloading manuals. Understand
that all of the listed powders can be unsuitable for the given combination of cartridge, bullet
and gun. Actual load order can vary, depending upon lot-to-lot powder and component variations.
