It's just a sidearm until I can do better out to 25 yds. At 15 yds it does well enough, but I all too often get one that opens it up to my 4" maximum.
Quite frankly I ought to do more testing to see if it's one chamber doing this or if it's me as I've read of several match shooters finding a chamber throwing their group off as well.
I have a 285 grn version of my WFN designed specifically for my ROA, and I've created a 245 grn version as well, but haven't bought it yet. That's the one I'd prefer for hogs as I'd want more mass than 195 grns.
I've posted links to these designs a few times but they always get deleted with a warning about posting personal stuff for sale or some such, which has never been the case. I've talked to the moderators about it but they keep deleting them anyway so I got tired of doing it.
I truly like the idea of your .40 cal, but the cost involved and figuring it wouldn't give me anything over my .44/.45 cals puts a project like that at the bottom of a lengthy list.
