Gunmark air-rifles/ air-pistols

M.E. = M x V x V / 450240

...Or simply E=1/2 m(v)squared. The constant helps you get the energy in the desired units.

This is what is popularly referred to as Einstein's mass-energy relation.

Hi Guys!

Over the past few days, I've been talking to Mr.Kulkarni who owns Gunmark Armoury.

After you patiently listen to his flauntings of being the defence adviser to several countries!?! and his winning the Diana Medal which according to him is a feat equivalent if not better than winning the Nobel! he tells you about his Gunmark .22 rifle which can beat the holy pellet out of a Diana 350 Magnum.

I liked his confidence in his product. So I shot a few questions to judge if this guy knew what he ws talking about. Seems like he did. He said that he had a US order for the rifle but will try and sneak in one for me at 11k. Now with local makes retailing for anything between 2 and 4k, this guy better be selling me a monster for 11k. I'm no Scrooge when it comes to spending. My AirForce Condor cost me 50k for the full kit, but I like to pay only for what I'm getting. I'm sure you'd agree.

I was game. I wanted to buy this thing. I went for the specs. Thats when I was shocked. He claimed 1100fps in .22. Now thats a handful. I asked him if he could prove it to me on a chrono and he went on to flaunting his credentials again! I shut up.

But, what excites me (if he's not bluffing) is that even if he was using super light RWS .22 Hobby @ 11.9 grains to achieve that 1100fps (most manufacturers resort to this pellet to get their inflated MV), it'd still be able to deliver a knock out with say Beeman Kodiaks @ 21 grains.

However, if this guy is really street smart, he'd be using the PBA Raptors that Gamo now makes. Then 1100fps would translate to around 950 in lead. Which is still a good figure.

Personally I dont put much stock in FPS unless the grain used is mentioned. Plus the fact that MV means nothing if accuracy is non-existant, makes it all the more important that the pellet used is heavy enough, not to deflect when exiting the muzzle. My Condor is rated at 1250fps at the muzzle. We chronoed it using the Hobby and the reading was actually 1290 averaged over the first 5 full power shots. But I could not even get a remotely impressive group at anything above 30 yards. We switched over to Kodiaks and the MV dropped to an average of ~900, but groups were comendable at 50 yards. Now 21 grain kodiaks starting off at 900fps and actually hitting the target is definitely better than 11 grain hobby's whizzing past the target at 1290fps.

So whats the deal with the Gunmark? will it actually make 1100fps albeit with the lightest pellet? If it will, 11k is a real steal!! Heck, even if it makes 900fps, it'd still out perform the Diana 350 Magnum!

What do you guys think?

[art_collector]

....haven't used his air rifles .......but he has been successfully manufacturing
P-10 air pellets which are the best flat heads we find around. But they do not manufacture air rifles ....may be they might be importing it...but then 11K is too less a price for the specifications that you mention.

[Mo]

Hmmm.. I didn't know about the P-10. He did mention GSmiths though. The Gunmark is manufactured by him. I confirmed that. Not the barrel though I guess, not sure. He said that they will be going retail in the next couple of months. The US deal was supposedly keeping them busy.

I know its too good to be true. But somebody that side of the country could pay him a visit and find out if its the real deal. If it is, then we're all in for a treat!

Sanjiv, howz that rifle doing now? still maintaining the punch or has it dropped.

[Mo]

Hmmm..

I did see that. But I read somewhere that they stopped production of that model. So I though this must be the new model.

If all the tall claims for the Gunmark are actualy worth a bet, then I'm sure we can expect a good turn in things with the local make actually getting up close with the imprted ones..

@Moderators: Could you please merge this post to the old one? It'll be helpful.

[mundaire]

Both Gunmark threads merged...

Mo, I'd take the claims of ANY Indian manufacturer with a pinch of salt... And would not buy any product without having handled it in person PRIOR to even considering making a decision.

If you look at the pictures posted by Sanjiv (Biking), the power-plant of the GSmith/ Gunmark rifle DOES NOT look like it could produce the claimed power levels...

That said, I'd like to say here that I have NOT handled this airgun and my comments are merely speculation on my part...

Cheers!

[Mo]

I see the point. It doesnt look that impressive to me either. But the optimist in me wants to give it a go.

Any way of getting Sanjiv's rifle chronoed? It must've setled into its MV by now and should be easier to judge I'd say.

The only reason why I even want to give it a try is cause of all the dealers I've seen, this guy knows his stuff. But that may come to a disadvantage as well. Albeit, I'd still like to have a go with it on a chrono. Nothing speaks louder than numbers!!

Plus it'll make more sense checking Sanjiv's rifle than one at the showroom cause the display piece could be rigged for all we know! This guy has the knowhow to do it anyways...

[Emery]

Hi Mo,

Could you please load the pics of Airforce Condor gun, please let me know how did you get it, is their a dealer or some other source.

Cheers Emery

[mundaire]

Mo, if you really want a quality air-rifle - I'd suggest stay away from the Indian makes... if you're the member of a rifle club, you could import one via post as well (albeit only in .177)...

Cheers!

Sanjiv, howz that rifle doing now? still maintaining the punch or has it dropped.

sniper,
not much of shooting with the rifle and its not broken in yet,since i guess atleast around 2000 shots was needed,
i am spending more time to perfect myself for the pistol in the range,and also had put the rifle in the workshop to get it scoped,last time i had taken it in my friends farm and was shooting at a distance of 40-45 mts on a spinner and most of the hits with gsmith dome pellets and splits were totally mushroomed,the punch retains well if oiled every 100 shots to keep the piston washer swollen,accuracy 'no complains'.
i had even done a video shooting while plinking and the pellet shape thereafter,wud like to link the video sometime later, since its still in the tape and not digitalised yet and not getting much time these days to complete that work.
since the rifle is not chronoed i can not possibly comment on the mv with any pellet,and the claim remains a claim since i also have no idea which pellet was used by the maufacturer to conclude on the fps,accuracy no doubt is good,and as abhijeet says one must def. try and shoot the rifle personally before concluding anything.
cheers sanjiv

[snIPer]

Thanks Sanjiv

[mundaire]

Sanjiv, even if the gun has an old style leather washer; oiling every 100 shots sounds like a recipe for disaster - the consequent dieseling is likely to ruin the gun! Also I have yet to hear of a SINGLE spring piston gun that can make anywhere close to the claimed power levels using what (inferring from your words) MUST be a leather washer...

Cheers!
