Glad I read till the end. Your post answers my question about the quality and expected life of a
Shibuya DX plunger in actual use over a longer period of time. The young man coaching me has tried a couple of times to get me to go for a
Beiter, but I do not see the value in a plunger that is 3.2 TIMES the cost. If the bow is properly tuned and the plunger set properly it is almost set and forget. The
Beiter is certainly nice with additional features, but the
Shibuya functions smoothly and appears to be robust in all the right ways. I have been shooting 250 to 350 arrows a day four days a week over the past three months and see ZERO wear on the metal tip. That averages out to 14,000 arrows over the past three months, which blows my mind. With 30 reviews at LAS it is rated 5 Star. My Shibuya DX shows no wear (just went and checked).
I am returning to archery after a six hour spine surgery a year ago so my form is by no means great or consistent. Additionally, this is my first attempt at Olympic
recurve having shot trad and barebow in the past. If anyone could break it it would be me. LOL!
The OP's excess wear must be from something out of tune as has been mentioned. Hope he will let us all know how he ultimately sorts it out.
