I've the AI version of the .30-30 and find it to be a great improvement on something that really does not need it. Shooting Nosler 170 Partitions I am getting abit over 2300fps and case life is 8 reloads easy. I shoot only first fireformed for hunting and anything else for target practice or to get my wife refamiliar with the Win. 94 in early hunting season. I've pondered the .38-55 barrel conversion with one of my 94's but the .30-30ai. works rather well for moose and does kill grizzlies better than most would believe..not a preferred choice but it has taken them down when necessary. One thing about a lever gun it is a fast handling in close package...in the hands of one who is familiar and skilled it plain works. There is alot of harder hitting calibers in my home but do have an affair with the 94's.
