I bought Dynapoint GT's once....... NEVER again........
When I first bought my Buckmark pistol I ran myself out of AE .22 Then I started chewing into my Federal Bulk supply...... I decided to go shopping. My local supplier of AE was out of stock, all of the local Wally marts and Canuk tires were out of Federal Bulks so I took the chance on some Dynapoint GT... Can tire had 6 Bricks in stock... So I bought them, all of them....... at the time I was shooting at 2 different indoor ranges 3 nights a week and I was chewing through 500 to 750 rnds of .22 a week. I figgured if they work well enough it may get me through a dry spell and maybe I just found another kind of ammo that works in my .22's.
I usually clean my pistol once a week, so about every 500 to 750 rnds, I have gone 3 weeks before in the past before it started to FTE and FTF....... I shot 150 rnds of the Dyanpoints, and the action wouldn't cycle fully in my pistol..... it was that fouled!
Accuracy was ok, but I consider a "lets unfoul the action break" unnessicary when at the range..... not to say i don't clean the action at the range from time to time, but fouling that bad is as bad as flyers every 2nd or 3rd round.......
I never have this problem with my usual ammo. So I returned the unopened boxes of the Dynapoints, and gave the rest of the opened box to a guy that annoys me at the range!
Of course the next week my local g-store got in a whole bunch of AE, so alls well that ends well, I now try to keep at least a case of each in "stock".... it has been getting a little harder lately tho......
Cheers
