Sam Yang RECLUSE357: UPDATE!

Well, the new TJ Enterprises barrel was finally machined and fitted to the SY357.  The barrel is from TJ Enterprises and is 25" long.  My thoughts on the barrel was to have the projectiles travel down at least 24" of the barrel and have the other 1" or so machined.  The reason being is that the TJ barrel has a slightly faster (tighter) twist rate at 1-16" and in airguns, due to the limited power plants, more friction causes loss of speed.  So to slightly make up for this, I decided to use a longer barrel.  25" TJ vs 24+" OEM barrel.  Or, have the projectile travel down 24" (TJ) of barrel vs 22" (OEM).  The last recorded speed of JSB pellets from the OEM barrel was 961 FPS.  The new speed of the same pellets is 950 FPS @ 81.02 grs.  OEM barrels mics at exactly .358" and the TJ barrel mics at .3572".

THE POINT OF THE TJ BARREL:
The goal here was to have a barrel that shot a multitude of projectiles more accurately than the OEM barrel.  The TJ barrel is also a better made barrel and it has a tighter bore.  The tighter bore better fits a wider variety of projectiles.  The Korean OEM barrels are known to be big for stated caliber.  Sam Yang calls it a 9mm/357 and the bore is anything but 9mm.  9mm is .355" plain and simple.  Its more 357 than 9mm.....lol!

ACCURACY:

YES....100 PSI more equates to better groups!  The OEM barrel shot roughly 1" at the same distance with these big pellets.  The pellets head is roughly .358 and the skirt is roughly .362-.363" which makes the head more of a bore rider.  While accurate in the OEM barrel, I wanted more BITE on the pellet.

Stay tuned, as I will soon have more info on performance from not only more pellets but also round balls and 357 cast projectiles.
