The Better Bolts will add approximately 100ft in range in the gun they are designed for. They are direct replacements. The undershot puts a sever back spin on the ball so it flies like a golf ball. You get a flat-line shot to the extreme range. You get more shots per tank because the velocity is lower (260-270). You will not believe what this bolt does.
The Cooper-T Products Autococker Better Bolts are older, so while they may be available used and in a few cases new, they are not commonly available anymore.
Only 10 foot increase in range and requires a stronger main spring.
For a complete and exhaustive review read my field report. As of today (Aug 20,2004) I have completed 2 of 3 tests comparing the Cooper-T Better Bolt. A brief summary is you gain 20% increased efftive range after 115 feet, the range gain is only 1% (10 feet) and you have to use more gas to shoot the paintball.
Since PBReview doesn't allow URLs in posts email me for a link of my field testing review or look at my user profile for my web page.
For those not counting the number of shots per fill and want to tweak out a few more feet this bolt is for you.
7 out of 10

the marker i have this product in is:
was stock, JUST added a WORR Hindge Traigger frame,
planet eclipse On/Off Purge & Mini Rail
J&J Ceramic 14 inch barrel,
KAPP Twisted Cocking rod,
Coopet-T Delrin Bolt(this guy is pretty unknown and has a GREAT product),
otherwise the rest is stock.
i usually use a dye trottle 91/45tank
only BLACK availible
This bolt is great, it is light and fast, lets my cocker rune at a lower FPS(saves air), looks great(all black marker,mostly) and was hella cheap. this cooper-t guy know what he is doing, and wht he did was designa great bolt and then produced a quality bolt, and all at a very reasonable price. when persons check out my marker it is one of the first things they really eyeball(i have yet to see another one in play).
i dont have the scientific proof or testing but i believe i made my marker quieter, faster, more efficent, shhot farther, and become more accurate.
this is a GREAT bolt at a GREAT price.
