What attracted me to this thread ws the fact that I have also been scouring local shops for Indian made air rifles. Let me post what I have seen - at least my personal impressions.
I visited 5 shops in the last 5 days. They can be differentoated by the pellets they sell and the air rifle mdels they seem to push. I will not bother naming names so I don't need to defame or praise any particular shop. I will talk about pellets in a separate thread byut I found it useful to remember the shops by the pellets they sell.
One is the Marshall shot shop. (+1 for Marshal shot flat head pellets.) The second was the Mastershot shop. Mastershot round head is best for me. The others will be described in the appropriate thread. Shop 3 is the India shot shop. He told me the pellets were "OK" I did not buy. Shop 4 is the Diana shot shop. Diana shot round head is OK in my hands. Shop 5 has the craziest pellets I have seen. Huge guys. This shop even had a large biscuit tin in the corridor which customers could shoot using those vulgarly large pellets. Those pellets were like opening a mouse hideout and finding baby hippopotomases inside. Three out of five shops demonstrated the "power" of their air guns by firing off blank despite my objection, but in retrospect my objection was probably silly because they must have been doing it for every customer anyway.
The "big pellet" shop had DAW rifles. They looked rough and ready like Fred Flintstone level tech. Cocking required some effort, and I think trigger action was smooth. I had never heard the name and Googled for it. My uncle, Shri Google has also not heard much about them. This shop had what i felt were the "typical Indian customer". Wealthy farmers from a neighbouring state who were probably looking for human and animal varmint control. Indian customers by and large do not seem to be particularly demanding and discerning. This particular shop had nothing but DAW, and a few large and vulgar looking air pistols. This was not the shop for me.
Next was the Diana shot shop. Friendly. Informative. Showed me the IHP 35 and quoted a good price. Pointed out a few new features about front sight. Told me that the smooth bore air pistols of .22 were bought for "self defence"

He had DAW and told me that DAW has a feature that allows some phosphorus compound to be placed near the muzzle to get sound and light.

Bought some Diana shot and promised to return to look at IHP 35
Next was India shot shop. Friendly. Interesting. He had a Chinese side lever selling for 37,000. Didn't bother looking at it. He also had some thing marked as xx International - may have been SK or AK international. This was an underlever India made 0.22 rifle that tempted me althogh I thought the price was steep -10 k) . he assured me that it was rifled, but I could not be sure. The assistant helpfully fired off two shots without pellets making me wince. The underlever cocking effort was huge - giving the impression of a bull of a spring. There were two safety catches for cocking, but the gun still scared me because cocking pulled back a metal piston exposing a gap big enough for two fingers to insert a pellet into the breech opening. But if the spring gets accidentally released while you are putting the pellet in its curtains for your finger and thumb. They will have to be fired out of the barrel

Looked fiddly and dangerous. I ruled that one out.
Next I went to Matershop shop. This guy is an old friend. He never has any names for makes but showed me an IHP 35 with no rear sight. A "rare sight" indeed huh? He informed me that "Complaints have come about Precihole" - but that is is definitely not what I have heard from shooters whom I trust. Bought Mastershot round and departed.
Earlier I had seen the Precihole in the Masrhal shot shop. I think I will buy the Precihole Orion soon, but may also get an IHP in due course - unless I get the courage to strip open my SDB 50 and do some operations on its insides. After reading the "Gunsmithing" thread I am getting tempted to do that.
The verdict from my exploration? If you are a keen shooter who looks for accuracy and power within the legal limit, follow the advice on this forum and go for Precihole or IHP 35 (or some similar IHP model).
If you simply wanna have fun - get the DAW or an SDB or even a cheaper rifle and simply have fun. Air guns, and I expect all guns are like Heroin. You can never get enough power. You will always want "more muzzle velocity" and "more penetration". But there are legal limits and that is going to hold you back. Befriend a good gunsmith or tune up your rifle yourself to get the maximum out of it. But if you are not into all that just have fun. Plink. Blast. Spin. Kill that maths text you hated in school. Whatever. No matter which rifle you have you will always find someone who has seen or has a better one. Simply pick up one that suits your pocket and get down to shooting and let experience teach you how lousy your aim really is and that the 6 inch spread you get is more about you than the rifle you want to blame. The only thing that is in your control - accuracy, is something you may never get no matter how good your rifle is. Better to shoot lousy and blame the rifle. If you need to see good shooting, become a member of a local shooting club.
