I've never done it to a 700 but 2 model 70's with the spacer spot welded in. I drilled the spot welds out and tossed the spacer out. I never put any spacer back in place both rifles still feed flawlessly. One is a short action 22-250 and the other is a 270 wsm. Both controlled round feed 70'sMy original idea was to use a 308win magazine box not the 223 one. The key would be to create or find a "long" 223 follower. I would contact Wyatt's to see if they could make the long follower.
May try this myself down the road.
