Thanks for the reply. I have the 8” Grimburg barrel in my VKS. Along with other mods it performs great. I was hoping for a little longer barrel for the TCP but it’ll work. Thanks for the suggestion. Take care.

Thats right..you dont want ur gun to just go pop-pop...as the bang alone sounds like a cannon!! it's enough to scare the BJesus outta several home invaders.

Great comparison test! Keep up the good work! Pretty sure I heard a leak with your eBay barrel after that fifth shot. I've never had a CO2 die out like that so that would make sense. Even at max velocity I can finish an eight round mag. 🤷🏾‍♂️

Thanks! I appreciate the encouragement. I heard something too on the video but not when filming. However, I'm standing right next to my furnace which came on at the same time and I had on hearing protection. You could be right though. In real time I ran the stock then eBay barrel, then swapped out to the Grimburg barrel last because it required changing out the screw. You may notice the same furnace sound still running during the Grimburg shots. The Grimburg barrel then ran well. I'll be doing more fine tuning so this is just N=1.

@@Ardeact There are 3 main ways to increase power in these launchers. You can add barrel length, increase the size of the air chamber, or push more PSI through from the tank or CO2. The barrel length is the only change that is free from stress on the launcher internals. The other two will cause problems with o-rings or damage internals eventually. I avoid the others, although many rebels just throw caution to the wind and go for max power.

Yes indeed. Kurt from Grimburg explained it to me by saying that doing this allows them to avoid having to get the barrels machined overseas and rely on the supply chain. The hole is a genius idea but it can wear. I've examined mine carefully over months of tension and although the outer coating has scratched some, the hole is holding up. Now I'm more concerned about the other end. The breech is the same tight bore and the firing bolt cannot enter the breach without hitting. In my mind that will limit the power setting that you can safely use without breaking the bolt. Definitely need a VKS spring if you are using a Grimburg barrel in my opinion.

I have compared them a couple times in the past. The first shot with either will be basically the same. But the fall off in FPS will be a little greater for shots 2 and 3 but then really fall off fast with the 8g CO2. So the last couple shots are weak. I do have some shooting with an 8g CO2 coming up at the beginning of a video scheduled for mid-March so stay tuned for that. I didn't chrono there but I show the power on a target. With the PRV delete kit from Daniel Sterling the 8g CO2 performs admirably but all things considered you can't go wrong with 12g. They are cheaper, abundantly available, and you can use all the CO2 in an efficient manner.

Would you have any problems if the barrel and round rifling configuration are mismatched. I have the A5 but I got the HP68s on sale which are rifled. They also fit kinda tight even though they're .684 and the barrel is .686

The Grimburg A5 barrels are bore-matched with their projectiles for better performance. It should be a very tight fit if you are using the Grimburg A5 and not one from somewhere else. However, I'm not aware of any A5 barrel that fits into the Pepperball TCP or VKS. What launcher are you using the A5 barrel in?

Could you possibly test the TCP smooth bore, which mine actually came with, vs the TCP rifled barrel.

@ScaredyCatTactical

2 жыл бұрын

I really like the way you think. That is definitely a good test with them both as smooth bore. Unfortunately, I don't have a smooth bore TCP barrel to do the comparison. At one time I looked for a Lapco 5" smooth bore but couldn't find one. However, I think I know what the result should be. Smooth bore is smooth bore and the TCP barrel is very well matched with the Grimburg JULs already and with a little bore matching like in my prior video, it should be functionally equivalent to a Grimburg 5" barrel. I certainly wouldn't buy the Grimburg barrel if your stock TCP barrel is smooth bore.

Optimized for the barrel is probably the most important take away among many other of your great points. I always setup for consistency rather then hail Mary's

Double feeds generally come from the regulator sear spring being too weak. You may consider upgrading to the VKS sear spring as part of the PRV delete kit sold by Sterling Self Defense. That helps a lot with conserving power and eliminating double feeds.

Good question. I don't completely understand the physics but I'm learning more about it. The longer barrel takes a split second longer for the air pressure to exit the system and a split second longer for the bolt to reset. That extra time however small causes air loss. Additionally, in this video I used my JULv2 that were bore-matched to the Pepperball stock and Grimburg barrels but not to the slightly larger bore eBay barrel and that also causes some extra air loss. The follow-up video that came out last week highlights better results all around when I switched to the eBay barrel bore-matched rounds. Check it out as well as the bore-matching video from this series.

@@sven471111 Yes the bore matching does reduce loses. That's why the Grimburg 5" barrel outperformed the Stock Rifled 5" barrel in this video. Less air loss so there was more power across the entire mag (see the graphs at the end). The length of the barrel is also part of the equation. Longer barrel does have an impact but I can't give you a number on how much (yet). These are complex topics that will take further testing. I'm an experimentalist who is seeking the right answers without caring what the answer is because I have no vested interests. As far as barrel availability I did talk about this in my latest video and give my reason why Grimburg is the way to go right now. I love their 5" barrel and the 8" barrel is getting great reviews. I think the screw method is sub-optimal but they have new barrels coming out that seem to be more durable and hopefully will hold up better to that constant tension. My 9" bore-matched barrel is functionally giving what I would expect from an 8" Grimburg barrel.

Removing the stock barrel is just a twist and remove. The Grimburg barrel uses a screw to hold it in place. It's easy but you do have to hold it tight and have a tool and you have to do that process everything you do service. Not hard but an extra step. I get the best results with the Grimburg 5" barrel per length not just in this video but consistently. My longer barrels will give more power due to the extra length (6" and 9") but they are much harder to bore-match projectiles. With the Grimburg barrel you just buy JULv2 and that's it.

Yes, longer barrels in general provide more acceleration of the projectile by the gas. A 12" will give better power than an 8" which is better than a 5". So rifled builds are always more powerful. The Grimburg barrel has the added power benefit that it's already pre-sized to match the JUL rounds so that less gas is lost per shot.

I know a lot of the less lethal community have moved on to kinetic rounds. But Pepperballs at the rate that can be delivered by something like the VKS is a very capable method of crowd control and/or could incapacitate a single shooter.
