New WAR valve and NB hammer in .22 and .25 Mrod

[Rdsail]

+1 with Motörhead comment. That is the reason my mrod 25 is tuned for 44fpe.

 I agree power is useless if you cant hit what your aiming at but thats where the end user (buyer)must be able to tune their gun. If your over shooting your pellet sure you will have issues, we supply the parts to get you from stock speeds up to supersonic levels with JSB Kings but its the end user who must set up their Guns to use the power correctly and Im available by phone 8 hours a day 6 days a week so no one will be left guessing what to do. There are many ways to set up a rifle (power,shot count,tight ES etc.) and these can all be achieved by your set-up, so as far as what parts are more accurate is kind of a hollow question its more of whats the most accurate set up for your desired  power requirement. I hope that makes sense and please don't be afraid to call me with questions about tunes or parts or drop and email travis@wickedairrifles.com

 Also one must understand that everyone isn't using their Guns for the same purpose for example I would never tell someone to go shoot a Pig with a 40FPE Marauder under any circumstance nor would I suggest a person Target shoot for groups with a 100FPE tune but being able to do both with the same gun at different tune levels well that's what I call a flexible power plant.

But just incase you were asking me:

It may not be the best tune for punching field target paper, but I think most would agree that with this kind of accuracy, for the hunters of possum sized animals, a broadside shot within the pictured target distance of 48 yards ( or less ), would be lethal.

BTW- this is for some of the other shooters

Shooting paper with a 100 FPE, 22 cal is quite possible. It takes boolits in the 45+ grain weight. Mine is currently de-tuned to 80 FPE to shoot 39 gr. That is just where it is currently happiest. I have a new mold that weighs more, and with that more energy can be delivered at what I hope is a slightly faster MV. I don't quite see it happening with a 20", pellet barrel...their twists are not fast enough, and the barrel not long enough. 50 gr is probably a reasonable sub-sonic limit for the 1:14 twist of the TJ liner in .224/.219.

I tried the .300, 26" twist barrel with the slugs backwards( sooooper boat tail ), and they were not at all happy. I plan some more adjustment, and likely de-tune to around 140 FPE or so...where ever I can find its happy spot I s'pose.

The next one is going to be .308 with a 14" twist and that will allow longer boolits( heavier too ), for even more energy... I am looking forward to a 200 FPE WAR valve...better yet, one that can run well over that in .357. Come on Travis, get with the high power...

it was pretty cool to get a SS crack out of a 28 gr EJ though...lol ( 1174 fps )

My .25 Mrod is all stock except WAR valve and hammer, 12.5 hammer spring, and barrel port opened to .187. Tried a new tune today with JSB's. Hammer spring preload=0 Striker=3. 3000psi fill
957fps avg for 16 shots. Winds were 12-20mph gusting slightly left to right and sometimes almost head on. I did try to some extent to wait on wind gusts, but was hard. Single sand bag rest shooting prone.
30 yards 8 shots .4" groups
50 yards 8 shots .875" groups
100 yards 4 shots 1.4" total of 8 shots 2.3" groups.

Doesn't sound impressive, but the wind was tough to shoot in and I did my best. If I would have had more daylight I would have setup my benchrest setup, but feel these groups were very good per the weather.

With my Eunjin 43.2gr tune of 8 shots at 861fps avg, I had groups under similar conditions of 1.4" at 50 yards for 8 shots. Didn't try at 100 yards but will when weather permits.

My tune goals are based on as much accurate power as possible for hunting game upto coyotes. I am sure that bringing power levels down for shot count and such would yield even better accuracy as pellets normally don't shoot well at high velocity. However, shooting in the windy conditions I have had lately, I think precision accuracy is very possible even at these high speed tunes.

Thanks for the update,  I'm keeping my eye on this gun.

[ajshoots]

Was hoping to shoot groups with the .22 today, but weather is not cooperating and we just got a new lab pup today. Hope to be able to get some groups with the .22 at 50 and 100 yards to post in the next few days. Would be nice to find a good calm day to ring out both guns and get a good feeling for what both are capable of in the accuracy department.

Thought I'd bring the topic back up to see if anyone has been using the war stuff.  I'm still interested in it.

[ajshoots]

Just an FYI. I was at 71fpe with 43.2gr eunjins. The accuracy was ok at 50yards but not good enough to go any further. I ended up going back to jsb's at 52fpe for 16 shots. Absolute tack driver even at 960+fps out to and slightly past 100yards. Meaning moa average out to 100 yards.

My .22 is up to 47fpe with 25gr jsb monsters. 20 shots and very accurate. This gun shoots alittle better than the .25 but not by much.

[LEE IN VA.]

Good to hear aj, are your guns wood or synthetic?  I'm just curious as to how they handle in the field?

[Bullfrog]

I don't have a dog in the fight either. I run one of the old A2A valves which are no longer in production. Maxed out I can push a 43.2 Eunjin at 997fps but only if I overfill to 3400 psi. I'll get 3-4 shots at the top of the bell curve and the fifth shot will start to drop. 5 shots use 400psi. I decided that isn't practical so I detuned back down to 880fps with Barracudas.

Concerning accuracy, I haven't shot groups with Eunjins beyond 20 yards. I do know they have a different point of impact at 20 yards at that power level than Rat Sniper Slugs or Barracudas (which both have the same POI with each other). I'm skeptical the Eunjins hold a good pattern beyond 20 yards but I think the slugs and the Barracudas would hold well.

Where I think the extra power helps is on body shots of larger animals when paired with a bullet or pellet that will mushroom easy. But I'm undecided whether the extra power is worth the decrease in shot count.

I do believe the beauty of these modified valves of whatever "brand" is that when they're modded or built right they greatly improve the efficiency of the Mrod's air usage. In my opinion the Mrod's greatest weakness is the inefficiency of its valve. You don't have to shoot for max fpe. Max efficiency is a better goal.

Interesting to see the MRod owners having the same experience as I did with my Hatsan AT-44S Long.... Crank it up to 75 FPE, find out there are no pellets that are accurate up there, and then tune it back into the low 50's with the JSB Kings and get a tack driver.... I surely hope that the new (34ish gr.?) JSB Heavy .25 cal pellets will allow us to create an ACCURATE quarterbore in the 70+ FPE range....

Don't want to steer the thread I that direction, just a comment....

I'm with bob on this one. One reason I might get a TJ barrel to shoot casts. We will see

I have the WAR parts in my 25 M-rod with 17 pound hammer (from Nat450) and shot 72 grain Black Mambas (also from Nat450) at a peak of 98 FPE.  Nat450 was able to shoot the Black Mambas with these same parts up to 104 FPE. 

Those Black Mambas are serious projectiles - comparable in weight to a heavy 223 bullet.  But I have not shot groups with them yet, but I did shoot an off-hand group of 5 at 25 yards that was pretty tight - all within squirrel kill zone.

I got some 43 grain EunJins that I will test out for accuracy over the next few weeks and will report back.

Now that's a heavy hammer 

Look out squirrel 

Seems like someone would have tried one of those valves with a .30 cal. by now 

[ajshoots]

I could get to a max of 80fpe with 43.2 eunjins with 12.5lb spring and 3200psi fill. Don't have any heavier springs or any slugs to try?? Was able to get alittle over 60fpe with my .22 10lb spring and jsb monster 25gr 3200psi fill. 

[Monkeydad1969]

So are the War Hammers the same, lighter, or heavier than a stock M-Rod hammer and what is the exact weight on them compared to a stock hammer?

Joe

[Rdsail]

hopefully I will be able to test a WAR valve and a max out mrod valve and compare them. That will be mixed with a 17# hammer spring and 109gram hammer.
