Just picked up a new handi in .35 Whelen the other day. Out of curiosity, I swapped barrels with my 45-70. The .35 barrel locked up perfectly on the .45 frame. The 45-70 barrel locked up pretty well on the .35 frame but has just a tiny bit of side to side play. It doesn't rattle or anything but if you grab the fame and the barrel you can feel just a little slack. My question is, is any play acceptable? I don't plan on using them this way but would like to know if I could. The .35 Whelen, by the way, is one of the new ones form Van's Sporting Goods in central Ms. Took it to the range Tuesday. I only had time to load 7 rounds for it using a 200gr Hornady Interlock and 55grs of Varget. Fired only one 3 shot group at 100yds and it measured .72in. Not a thorough test, but a very promising start.
