All very good points, AGS and Jon. Thanks much for sharing your thoughts on this. Any untested loads would definitely be sent to Armbrust for pressure and velocity testing. Jon, you and I both have lots of experience using .410s in the field, and I respect your opinions on this. I would, however, prefer to keep the velocities at 1200 fps or less. Why? Because I have found that most of my S X Ss are regulated with heavy-for-gauge payloads at lower velocities. I have seen some drastic crossfiring of S X Ss when they are fed lighter payloads at higher velocities.
I will definitely save your loading suggestions if I decide to chase this rabbit. I may decide to be satisfied with my .73 ounce load of nickel plated 8s at 1175 fps. It has really been shown to be a clean killer for me. TBH, getting the rims cut down on a lathe and opening the primer pockets on 100 cases does not sound very appealing to me.
Thanks.
