30 ihmsa

Can anyone give me some basic load info for the 30 ihmsa in an xp-100? Thanks
These loads are from the IHMSA Reloading Guide for Handgun Accuracy published in 1982.
For 150 grain bullets, these are the suggested starting loads
26.5 Reloader 7
27.0 4895 (Didn't specify IMR or H0
32.0 W748
These are the loads for 150 grain bullets that provided the majority of best scores using the same powders
30.0 Reloader 7
31.5 4895
34.0 W748
I shot a 7 INT Wichita for years using 139 and 154 grain bullets with 32.0 of H4895
I would suggest reducing the starting loads about 1 or 1.5 grains and work from there.
30 IHMSA (aka 30 INT) is a very good cartridge and you shouldn't have trouble finding a good load for it. Would be a good cast bullet cartridge too.
If you need dies, check out CH4D in Mount Vernon, OH. Quality dies at reasonable prices.
Good luck and have fun with your XP.
