Re: Wildcat for beginner?
Its a double edged sword. Yes you will learn, but you might question the point of it. Generally, to know why one would want a wildcat, you need to have experience with a "regular" cartridge first. Many wildcat cartridges will wear out barrels faster than standard cartridges. In the case of a 6.5x284 (and probably a 6.5WSSM) that might only be 800-1500 rounds total. Along the way the throat dimension will be changing and your seating depth will have to decrease to keep up or there will be drastic effects on grouping. YOU will have to be staying on top of all those changing variables with probably little hand holding from outside.
For someone not familiar with fireforming, reloading, working up an optimized load, while sparing barrel life, this can be a very frustrating experience. On the other hand, once you are familiar with the reloading process and have a workflow to "find" optimized loads efficiently and understand that a wildcat is like a dragster (high performance, short life, high maintenance), it is a more rational point to go that route. Many people will take a total hosing on their wildcat project in the cost of the barrel, brass, dies and finally giving it away when it provides no satisfaction.
The ideal situation is that you have both experience, and plan to do challenging shooting (600 yards + on a regular basis) where you could actually see the benefit of the wildcat. If you are just shooting at 100 yards on paper, I think you will tire of the "all work and no reward" very quickly.
