ok, i am sure that this is not a first time question, but as a beginner looking down the road i am trying to understand all this wildcatting of different cartridges.

i think a big part of it is for the fun of the shooter, trying different stuff, playing etc. i understand that feeding action, and felt recoil and stuff like that all play into it, but are people really finding huge performance changes in these wildcats.

i am gonna use 30 cal. as an example. on the low end is 30 carbine, w/ 308, 30-06, 300wsm, 300rum etc., this covers a huge powder range/capacity for the same batch of bullets, from basically 110gr, to 240gr, w/ a host of powders to push them. i used the above example because i own all those chamberings (except 30 carbine) in quality rifles.

the wildcats out there are enormous in just 30 cal, and with other calibers the options are even more over the top. from my perspective w/ all the various capacity cartridges already available in factory brass and inexpensive dies, what is the advantages of going down the wildcat trail?

i realize i can ask this about a host of caliber's, .22 cal is even bigger in wildcatting, but w/ .223rem and 22-250 readily available and reasonable, does someone really need to go down that road to get better performance, or have i completely missed the point here?
