I have both of these jags. I am going to order some 1 3/4” square patches to try, I also plan to get some 1 3/8” patches to sample. I only use proshot patches and for my 7mm I have been using their 2” round patches on a .22-6mm proshot tipped jag.Get a Parker Hale style jag in 7mm and 6mm. 1 3/8 Proshot patches with both, and any other caliber with the correct caliber Parker Hale.
