Never ever use pellets that are damaged, disfigured or as Yash says "...that it gets damaged while inserting...". This is 'Bhayankar Hanikar' to the rifle. Like I said earlier, there may be a small variation in the pellets (Not the rifle barrel), which is made for new to old guns.yash3_great";p="51554 wrote: My experience has also been that the Gsmith pellets r very tight for an IHP both in .177 and .22 cal. I believe the reason is becuase the calibre of IHP rifles is not exact but a little less. At times the pellet is so tight that it gets damaged while inserting into the chamber.

Here is a greater detail of the sight adjustments:
Data:
Rear sight is the one that sits with the 'V' closer to the shooters eye; Fore-sight is the one that sits with the '|' on the tip of the barrel; No adjustments can be made generally for the fore-sight, unless there is a huge variation and the foresight needs to be filed.
Understanding the Theory:
There are two planes of adjusting the rifle (or pistol) sights. I shall try to be as de.scriptive without images.
The first is the vertical alignment (top-bottom line) which is controlled by the main (big) round knob directly on top of the center of the rear sight. By moving this clock-wise, the rear sight goes down, which in turn makes the pellet shoot lower. By moving this in an anti-clockwise direction, the rear sight moves up, which in turn makes the shooter aim with the fore-sight higher to adjust to the change in trajectory path, and the pellet shoots higher. The rear sight vertical adjustment knob has numbers and can be checked with the number of 'clicks' that one can feel while adjusting the same.
The second adjustment, which is the Horizontal adjustment (left-Right line) is got about by the side knobs of the rear sight. Some rear sights may have two knobs, one on either side, but the IHP has one to the right of the rear sight. You may need a screw-driver to make adjustments for this. There are no clicks provided in the IHP too. Moving the knob in a clock-wise direction, will in turn move the rear end of the rear sight to the LEFT. This will make the shooter aim a little to the left resulting in pellets going more to the left, and vice-versa (Anti-clockwise will result in pellets going to the right)
Adjusting the rear sight aperture:
Apart from this, some IHP guns have a small adjustment to change the rear sight view from 'V' to 'U' to 'v' or 'Џ'. To make this adjustment, slightly press the small spring based protrusion directly behind the 'V' and turn the small plate that projects out on the rear of the rear sight. This is a little hard to explain without a diagram, but is a small adjustment which a few seconds of curiosity and learning will make one perfect.
That is the basic theory part of the application.
Putting theory into Practice:
Now to put them into practical use, what a shooter should be advised is to shoot atleast 3 shoots on the target, without scoring. This gives a general direction of where the grouping is. Based on this, required corrections are to be made with a few clicks at a time, and another sighting of about three shots be made before making more sight changes. Once again the general changed grouping should be noted and required adequate clicks made in the rear sight.

Note:
1. For some shooters, there will be a big change from 'benching' the gun, and from holding it. This is based on the shooters stance and grip.
2. Some rifles may shoot drrastically to the bottom, and the least setting of the rear-sight may not be helpful. For such situations, one will have to slightly file the fore sight, so that the shots come closer to the center. This adjustment has no CTRL-Z to it!!!
3. It is good for shooters to note the numerical changes of the main rear sight adjustment (vertical) between different distances. That way, the shooter can quickly make rear sight vertical changes by approximating the distance of the target, and get good accuracy from the first shot itself. (For example, if '3' is read for a 10 m target, and '9' is required for 20m, this can be memorized/recorded for quick adaptation.). This may not be same across different rifles.
