Umarex Hammer

When I looked at the PA web site it stated expected in stock date of 7/31/2018. I'll wait awhile.before ordering. Rick E. has a video of them shooting it at the shot show range. Stated three shots per fill but they filled it after two. Had a short easy cocking stroke. Looks promising for sure but they never showed the groupings. Saving that for a more in-depth video. If they keep pumping out 800.00 bigbores from the big name manufactures our custom makers are going to be hard pressed to stay in business. 

I love the concept of the Hammer, which is a powerful, repeating big bore pcp. I don’t like the 4500 psi fill pressure as others have stated, and I have an Omega Supercharger with a CF tank. With the Texan .457 you fill to 2700 psi and that gives you 3 good shots printing all within an inch at 75 yards shooting a 290g Nielsen bullet. We are already having complete pass throughs on deer with this set up so more power isn’t an issue with a thin skinned animal like a deer. I wish it were more compact but Airforce is coming out with the Texan Carbine to address that issue. I would be looking into the Hammer if I were hunting Elk but not in SC. Again I applaud airgun manufacturers for the continued development of big bore airguns, just not at 4500 psi. 

I'm excited about the Hammer but I'm also a big fan of the Texan. Gamo's new TC45 looks a lot like the Texan and uses a carbon fiber 3600 psi tank. I'm just wondering how you get a full fill on a 4500 psi gun with a 4500 psi tank. It's not possible right?

You can fill to about 4500 but with each fill it will be slightly less, the 3rd shot will have slightly less air for each shot until it becomes less and less powerful.

Two 4500 tanks cascaded would be good. A 4500 60 min tank will take it a long ways. 

I hope its accurate because my texan is. 

I use this and the Yong Heng compressor with a cigarette lighter adaptor to fill my tanks and guns on the go. The 12v portable compressor is especially handy as I don't need a bucket of water to cool the cylinder, nor do I need to add any oil, etc.

Why don't you guys like the fill to 4500 PSI? I personally love it as it is needed to get the extra velocity the Hammer is capable of producing. If you guys are having trouble filling to 4500 PSI you need to set up a cascade system as you are not getting all the air out of your tanks. Rather than buying a big cylinder, you would be better off buying a couple of small ones and running a cascade system in order to get the most out of your cylinders. You don't have to fill it to 4500 PSI for the gun to be effective, but if you do fill it to that PSI the gun will of course be capable of producing much more power. If they limit it to 3000 PSI we lose almost a full TON of pressure per square inch.

I bought mine here for $350, including shipping. It works great but is a little slower than the Yong Heng. 

I was skeptical at first because it all seemed a little too good to be true, and the people who build these only speak Chineese. I first ordered the Yong Heng compressor off Ebay, and then I saw this a few months ago on YouTube. For all I know I am the only American with one, as I have seen nobody else on YouTube using these. Through research I was able to find out the guys who make these compressors are actually engineers that work for an Ameriican firm in Shanghi, by the name of JTC engineering. They actually make air cylinders, industrial compressors, and interestingly, components for internal combustion enginees for companies like Ford. 

Now I am a Rescue Diver in one of my part-time gigs, and I used to be a fill operator at a Dive Shop, started when I was 12 years old for my uncle. I have been around SCUBA compressors all my life and like to think I know my way around them. So I had no idea how they were able to both make a compressor so small (the ones we use at the shop are the size of a Volkswagon Beetle, and they EAT oil), and one that didn't need to be water cooled OR oil. So I started doing some more research and found that what they did was basically take the cooling system for a car engine, surrounded the piston cylinder with cooling heads in 360 degrees, which means no water cooling. Needless to say I am impressed. 

The low cost of these compressors has made shooting MUCH cheaper for me, and much more convenient. I am literally never out of air, and since I can fill my own tanks, I bought 4 used carbon fiber tanks off Ebay for $300 bucks from a fire station that had to get rid because the tanks were past the imaginary 15 year lifespan. I'm not worried about that as I used to inspect and repair SCUBA and SCBA tanks, and I have never had one fail hydrotesting in 40 years. Not to mention that the carbon fiber tanks are overengineered to a much higher standard than my aluminum SCUBA tank (which is good forever), there is no reason the tanks should expire other than the fact that DOT regulations specify it, and the bueacratic budgets require it. I saw people paying $777 dollars for a 9L tank and fill hose, or $500 for a 6.7 L and had I not had the experience and training I did, I would have spent about $2000 more for everything I have now. 

If I can answer any questions or help anyone build a cascade system, etc., please let me know as I want you all to enjoy this as much as I do, and I want you to spend your money on shooting, not filling your tanks with free air. 

Thanks for sharing that link BlindBallein. I have been holding off on buying a compress (still am) as technology there seems to be making fairly steady changes in improvements, as even with this product its the 4th generation. I really like the concept and may have to consider one of these over the Yong Hen style.

Do you personally have a preference over the two? Also couldn't one convert 110/120 down to 12v to use this while at home? Wonder how many amps this sucker pulls...I looked at all the information and didn't see it noted, I did see it noted it uses 300 watts, which would mean it runs at roughly 25 amps which would have higher than normal requirements than a typical house has in terms of breaker/wiring/outlet, but one could likely work around that if they were savvy enough?

No worries, glad you found it useful. I prefer the Yong Heng because it is faster, filling a 9L carbon fiber tank in about 45 minitues (10 minutes rest at 30 min). I use the 12v compressor to fill my smaller Ninja painball tanks which I modified the regulator on to output 3000 PSI rather than the standard 800. I also use the 12v for direct fills to my gun, as my FX will fill to 4500 and I get 95 consistent shots. 

I use a converter I bought of Amazon that converts 12V from my truck to DC 120v and it works just fine for the Yong Heng. Just remember to bring a 5 gallon bucket so you can fill it with water so you can cool the compressor. The 12v compressor is desgined to be portable and run from the 12v battery on your vehicle, which is exactly what I do. Leave the vehicle running for a more efficient fill and easier time on the compressor. 

I run the Yong Heng 110 v from a starndard outlet in my garage and even though it's not supposed to have an automatic shutoff on the 110 version it actually does, alarms and all.  

I haven't had any issues with either compressor in 3 months of use, and over 25 complete cylinder fills of 9L cylinders, and no telling how many fills of my 90cu Ninja tanks. 

"cfarm"Awesome information, thanks for sharing BlindBallein. Ordering the 12v. I too have a Yong Heng. Will be all I need for my present fill needs. If i do get a Hammer this year ( in negotiations, I don't like that whole sleeping on the couch thing), I may get with you on how to build a cascade system. Again much thanks.

LMAO! I’m rooting for you bro, fingers crossed! The couch is no fun, now you know why I am divorced. It took about 37 days from date of ordering until I received it. I have the guys email address if you need it, but they do respond to questions through the website. Good luck! 

ps. How is your Mandarin?  

"AGFAN"I'm excited about the Hammer but I'm also a big fan of the Texan. Gamo's new TC45 looks a lot like the Texan and uses a carbon fiber 3600 psi tank. I'm just wondering how you get a full fill on a 4500 psi gun with a 4500 psi tank. It's not possible right?

Gamo's new 45 is a re-branded Evanix.

Cfarm, 

Well they say the 3rd time's a charm; either that or you are a glutton for punishjment. I use this one and have had no issues with it. Good luck!

I have several .50 moulds from way back when Maxiball and Buffalo Bullets were the big deal. I am curious as to how my 300 gn sabots that I use in my ML now work in the Hammer.
