I know that people always say that you can learn a lot , by repairing a precarve , and getting it going. There is truth to that . I personally find that I`ve always learned more from a blank. The reason I say this is that , if I repair a mistake someone else made , I learn to do the repair. If I screw it up myself , then have to repair it , I learn not only the repair , but what led to it , and not to do that again. The folks running them off , obviously don`t try to fix these issues , or you wouldn't keep hearing about the same things all the time. I`ve built a ton of precarves , but I still prefer a blank , much more freedom ! If you ever hope to really be able to do whatever you want in gunbuilding, blanks are the way. JMHO NAte
