QL request

[wisconsinteacher]

Could I get some quickload info? I can't find anything for the 7mmRM with the 150 Partition and RL22.

I will be using Win brass and CCI 250 primers out of my Browning A-Bolt.

Thanks

Thinking about starting at 66 grains and going 67 and 68 to see if that gets me close to 3100 fps without any pressure signs.

I would start at 63 grains and work up from there? 7mm Mags are pressure tricky sometimes and go over very quickly.

Thanks for the info.

Seems like your recorded speeds were pretty close to what QL advertised.

 

[wisconsinteacher]

Yes they are close. Now to get the seating depth nailed in. If that happens, there will be smiles in NW WI!!!
