First off this is a follow up on a previous review.
Good? Well packaged for shipping. Doesn't break in the barrel. Marks real nice.
Dimples/flat spots, oval shaped, a seam that looks like the line you'd walk after drinking a 12 pack of 6.2 beer. See conclusions for ugly details
Just got back from shooting about 400 DS balls (not a typo) through my tippman 98 custom with a tru-flight barrel (polished). Miked the barrel at about 0.687 to 0.690 (rifling makes it hard to pinpoint). Chronoed at an average of 270. Moderately warm day (about 75), no wind to speak of, about 40%% humidity.
Results: No barrel breaks (kinda amazing considering the following)
10 balls stuck in the barrel and were shot out! Wow, no barrel breaks!!
5 balls dropped within 5 ft. of the end of the barrel.
3 balls wouldn't drop out of VL hopper without shaking, firing rate less than 2 rps.
At 60 feet, only 50%% hit 12 inch target, shot over/under and at either side.
At 75 feet, 10%% hit 18 inch target, 50%% did not even get that far.
At 100 feet, out of 20 shots only two got that far (had to lob those).
Additional info: Newly arrived these balls? eggs? had many flat spots and were not very round, but shot okay. After about 2 weeks, most flat spots were gone, but more oval shapes. After about 3 weeks, very few flat spots, but many many oval shapes (some about 0.68 on short axis, 0.70 on long axis). These things don't appear to age well.
Should you buy them? Do you feel lucky!!? Some people appear to be getting good (real fresh?) batches, others aren't. If you usually shoot at less than 50 ft. most of these might hit your target. But, the bottom line is, buy some (500 or so) and try them out......who knows, you might get lucky!! Me, I'm going back to Brass Eagle, same price and I can get them at Kmart (same lovely smell too!).
