Indians For Guns

Hai all,
I have been a huge fan of .177 air rifles, I had a 35 .177 for 6 months two years back. But was on a situation to sell it. So i was thinking of buying a IHP 35 .177 since then, recently bought a IHP 35 .22 air rifle (Review video is already posted) but was not impressed with the rifle when comparing my .22 cal Ak air rifle.

So sold it and Now I have bought a IHP 35 .177
In addition to that I got a Old model IHP 35 stock alone, Which has a thinner grip area compared to the new version. I love it!
So i refurbished the stock to look like new, And the combination makes me feel so happy.

i would like to add some photos of my rifle. and performance




There were only three rifling grooves inside the barrel wonder why?


And now some works done
Fitted a ventilated rubber pad

And opened up my rifle and lubricated it,
I had a Tune kit bought from Target tune India, Which was used for more than 1000 shots in my .22 IHP
Fitted them inside (Apex seal was not available so used Factory Seal only)
And Calculated fps of the rifle after and before tuning (Using Audacity) "Thanks to briha sir and Bennedose sir for teaching this technique"
BEFORE TUNING (Just took three shots)
Pellet: Gsmith Amature
1: 578 fps
2: 559 fps
3: 565 fps
Average: 567 fps
Pellet: MasterShot (White box)
1: 572 fps
2: 592 fps
3: 578 fps
Average: 580 fps

After Tuning (Took Five Shots for each)
Pellet: Gsmith Amature
1: 674 fps
2: 607 fps
3: 703 fps
4: 684 fps
5: 793 fps
Average: 692 fps
Pellet: MasterShot (White box)
1: 693 fps
2: 734 fps
3: 757 fps
4: 793 fps
5: 757 fps
Average: 747 fps
Results were nearly consistent after Tune.
Still Piston Seal has to be changed and a good new spring will surely increase the results I believe.

Shot Some groupings after Tuning
Distance: 10 Yards (Measured Eactly) from the muzzle of the gun to the Target
Position: Standing
10 shot group
Zeroed with Gsmith pellets only.
Pellets Used


1: MastterShot Pellets

2: Gsmith Pellets

Comparision




So That's it!

Hi Satya,

PS: Where did you get the "Ventilated Rubber Pad"?

Beautiful.
Your grouping photos confirm my findings about Mastershot vs Gsmith

good groups Satya.....

I have never counted the grooves on a ihp..... so how many do they normally have?? for that matter how many grooves do most Indian make AR's have ?

those 3 grooves look very well defined though. breach seal ??

All said and done ....
Satya you are a great sniper.......
Kudos !!

Thank you for your positive response.

I got the rubber pad from cochin may be 3 months ago, It was bigger in size so din't use it. but just now thought of sizing it. I used some Knives and files and was able to fix it exactly now its fine.

When these pellets are comapred externally Mastershot looks to have a good finish overall, Smooth,shiny,perfect round skirt etc
The only issue is that its of lesser weight than Gsmith and also the head size seems to be same as skirt so need some effort to insert it into breech.
But even though it was able to group 7 pellets in the same hole

I too have not counted them exactly before, But i have seen them and I am sure that there will be many grooves.
Like this pic below...... (This is a lothar walther barrel)


And also i have seen a review video of a MAC1Hunter air rifle having only two grooves
And he reason behind that was later told from the company that, These less grooves make the pellet steady while moving And the main factor is NO SPIRALLING of pellets. (Flyer's we say)

I have attached a pic of the Mac1Hunter air rifle barrel with only two grooves


Some guru's please make suggestion on my idea! And Pardon me if i am wrong, May be

-Sathya.

WoW...really you have good piece..enjoy the shooting

Sathya.....the number of grooves imo, do not really affect the accuracy of the rifle. it is the twist rate , depth of groove etc that helps stability.

the LW barrels are of course great.

FX has the new smooth twist barrels that are quite revolutionary. check out their web site,,,there is a good video of the barrel there.

I would think most Indian models have 12 grooves.

You are right... It increases the twist rate...but when a pellet twist much in a high speed travel there are some chances to deflect from the path of the straight line..... So a wobble occurs. Not all of them does it Only one or two pellets..... (or you can see pellet spiralling in a high power air rifle using less weight pellet mainly in FAC air rifles)
I too searched over the web for info and at last suggested this might be the solution behind the less number of Land in the barrel.
Please check this video............. Time 7:05 to 8:10

> You're right - the twist is 1:12 approx depending on how precise the rifling is done....
> Unlike fire-arms ARs need this spec. due to the pellet's lower velocity as compared to fire-arms...
> The higher the rate of spin - the better the pellet is able to maintain a straighter flight path...
> Also a snug fitting head dia. of the pellet helps it to engage with the barrel's rifling to minimize tumbling...

sathya.sniper,
good review
I also have IHP 35 in .177 & the grooves of .177 is far better than .22
For more info regarding the twist rate & it effect on power & accuracy read this blog from pyramyydair
very well explained
