IMR White Hots - Oil VS Non Oiled barrel
Some of you wanted me to do this test again but with the other subs. So i started with the IMR White Hots today.
First off, im very shocked to see how slow these things are! A 100gr American Pioneer 2f charge is actually faster http://www.huntingnet.com/forum/upfiles/smiley/eek2.gif
I used the CVA Accura V2, 245gr HP Powerbelts, 100gr IMR White Hots, Lightly lubed the barrel with Birchwood Casey Barricade, followed up with One dry patch and used both sides to mop up excess oil. Barrel was cleaned, oiled, dry patches between each shot.
Shots One through Three are listed below.
Pretty impressive spread wise, but Velocity was a lot lower than what i thought it should be.
Cleaning the V2 again, i followed up with Birchwood Casey GUN SCRUBBER to fully clean the bore free of any wetness and oil that may have been in there.
Loaded up again with the same load i previously shot and here are the recorded numbers:
21 FPS Spread. Not bad, but still not impressed with the velocity.
One odd deal i did run into with the non oiled barrel is the crud ring. Even though it was free of oil, the crud ring was much stronger and baked onto the Stainless Steel much harder and requires 6 pumps total of Birchwood Casey muzzle magic foam, and 3 patches. This is an area i want to experiment with more and see why the crud ring is worse with an oil free bore.
I will be chrono testing the T7 pellets next time out and see how they react to the same tests.
