Please read my comment of January 24 9:31 am. An update of the story.

Almost 2.5 years took me to make my Bantam Sniper HR .25 Cal to shoot accuratelly.

I know that many experts in this forum would get to the same result in very few minutes.

I want to share my movements to make those that could be interested to get faster than what it took to me.

This is what I had to do:

1.- Removed the end cap of the shrouded and made one with a wider hole to allow not cliping. A turner made it for me out of a bar of kevlar.

2.- Changed from 25.4 JSB´s to 34 JSB´s

3.- Removed the piece that screws to the end of the barrell. Theoretically that piece centers the barrel in respect of the shroud.

The number one movement was obvious.

The number two was obvious.

The number three came after thinking and thinking why the rife was accurate when the shroud was removed and the barrell free but once I reassamble everything the accuracy always was aleatory.

I was tempted to change the barrell for a LW poligonal one, but that would had been sacrificing the comfortable lenght.

This rifle is now admited to the very select group of "trusted rifles", normally restricted to Airgun Technology (Vulcan 2 and Uragan), Daystate and FX. The Bantam now has the following advantages: A big Omega cilinder, perfect ergonomics, lightwieight, excelent number of shots per fill, perfect lenght and the desired accuracy at very long range.

In the Bantam there are two best in the industry (according to my preferences): the magazine and the safety.

Now I'm curious. A pic would be appreciated.

Friends of the forum, I anounce the birth of a monster:

The recrown process was an astonish success:

Now the Bantam can compete with and perhaps win at 100 yards to my must trustable rifle at that distance (Woverine HR HP ART Barrell).

Now the flight of the pellet is perfectly straight.

Final configuration:

1.- Removed the end cap of the shrouded and made one with a wider hole to allow not cliping. A turner made it for me out of a bar of kevlar.

2.- Changed from 25.4 JSB´s to 34 JSB´s

3.- Reinstalled the piece that screws to the end of the barrell. Theoretically that piece centers the barrel in respect of the shroud.; And

4.- Recrown of the barrell (first time in life I do it following a youtube video).

I used my drill first with a round head screw (did not like the result) and later on with an extrange tip that once I bought. See the pictures of both.

In order to avoid small pieces of metal going to the internals of the rifle I rested the rifle horizontal and when finished with the drill, I pointed to the floor and then shot two pellets to the grass in order that the pellet and the air could expulse any piece of metal that could had enter into the barrell.

Here the two partners of the drill fort the recrowning:
