It looks like I should be able to load out to close to 2.28. I'm limited to a 5 round mag for hunting here. My ASC that I dedicated to this NY fixed mag, top load, build measures out at 2.305. Using a Hornady modified case and gauge, I set one to 2.28 without touching the lands. If I'm measuring correctly, the 129 starts to jamb in the lands at 2.385. Does that sound right? Isn't that a huge jump? I'll load up a few dummies at 2.28 or maybe 2.275 and see if they'll feed reliably.
