Thread: Starting a Ladder for T3 7mm Rem Mag with 162gr A-max's

Hi All,

I've managed to collect just under a hundred rounds of Federal and Norma factory brass now, So have set up the Lee reloading station and FINALLY managed to get hold of a box of 162 gr A-max's

Previously I've been shooting !50 grain SP Federal Blue factory that groups sub moa on average (about best is .75 inch@100m) and 140 grain TTSX Norma factory (cloverleaf 3 shots happily@ 100 and about .5 MOA average)

So I'm looking to create a ladder for my reloads and testing the load development on the 200m Rage up here in Auckland or at the Farm. I'm using a 7mm Rem Mag T3 lite Suppressed(as that's what I use in the field). and I'll be using Federal Match Primers for the 162grainers in once fired Federal brass and will be using IMR 7828.

Has anyone run exactly the same (or very similar) load development as this so I can compare and decide the start, mid, and top of my trial ladder to reload to. I don't have a chrony at this stage to map the speeds but happy to share info with my results and the advice coming from you guys with experience in such matters.

I'd like accuracy over a group over a speed race guys - so any thoughts? where to start load wise for the A-max?

Best regards
P.
