*let the pelting from the nasty phoon squad commence*
I do not say this lightly, as I am still very much a Palmerite. However, test results speak for themselves.
I got the hammerhead kit today in the mail, after having bought a full kit off of ebay for $100. Now, originally I thought that the fins were A-5 threaded, but it turns out that I recieved an autococker kit, but with a barrel adapter. Okay, slight disappointment, but no big deal. So, I go over to a friend's house to shoot a pod-full of paint with this sucker. I use the template to find the best bore.
Paint used: Empire Engage
Fin selected: 0.686" bore
Here's the results (will hopefully have actual ranges for you later, along with strict range test data, accuracy data at different ranges, etc.):
Total barrel breaks: 1
Average grouping at 50' (distance and average grouping were eyeballed): 6"-8"
Average grouping at 100' (also eyeballed): about 12"
It kept its grouping tight even during rapid fire, and I often got balls hitting on top of each other. With the PPS barrel, groupings were nice and tight, and I could really precision shoot, but this barrel takes that to a whole new level.
The only complaint is the break I got. I haven't had a barrel break since I used marbs in the dead of winter in my blazer back in winter of '03. And on Saturday when I used my PPS barrel, I shot at least a hopper of crappy paint and didn't break a single one. Now, with the HH, I broke a ball in it using quality paint. So the PPS barrel has reliability on its side over the HH.
Now, there will be times that I will opt for the pps barrel. Times like when I am using paint that is really tiny, or fairly large that I'd rather want a super reliable barrel that also shoots blasted straight over the super accurate barrel that on occasion breaks balls. Like, winter play....I'd totally opt for the PPS barrel over anything else. But for fresh, high quality paint in non-winter play (I DO play in winter, take note), I will choose the HH.
Barrel specifics: Hammer Head Pro Series 12" barrel, 5 fin kit
Threading: Autococker (a-5 gun to autococker barrel adapter included)
Now, in relation to cleaning. The HH was fairly easy to clean, but the thing is that you really can't shoot through the break. When I had the ball break, my groupings went down to those comprable to the A-5 stock barrel's groupings at the same ranges.
Anyway, barrel rating is 9.5/10, it gets the -0.5 points for not being reliable as my PPS brass barrel in ability to shoot varied sizes and quality of paintballs.
Edit: I WOULD like to state that the groupings I attained today are groupings I have only achieved with one other paintball gun + marker + paint combo, and that was with my PPS blazer with a 12" spiral ported barrel shooting marbalizer, and running on an anti-siphon 20 oz. CO2 bottle. Note that that was a totally palmerized setup.
