Throback i tried that with my savage and i think the max mag length is 2.840..when i did that it was actually jamming into the rifling on my savage..and sure enough when i used the old bullet in the knotched cartridge trick it was 2.825 to the rifling so i guess you can't always use the magazine as the benchmark? i hear conflicting reports that wedging it in the rifling increases pressure while other's say it totally fine to and some guys do load them that way...it's all so confusing! ahhh!! haha guess you just need to be cautious and work up all loads carefully watching for pressure signs.
