Tips for shooting the .22 No.08 Cadet Rife.?

Marksmanship isn't just about "tips".

A person needs to devote themselves to learning & properly practicing the fundamentals of rifle shooting.

While the basic lessons seem simple enough to understand with a few hours of instruction, gaining true mastery can elude someone for their entire lifetime. Don't be discouraged. It's a journey that's worth every patient effort and one that requires a lot of "hands on" experience.

 I'm going to give you several links to more information to get you started. Some of it may translate directly while some of it will have to be adapted to your situation.

A Rifleman will know how to use the bone structure of their body to support the rifle in several shooting positions. They will also know how to practice "breathing control" and to properly squeeze the rifle trigger. They'll know a lot of other things too, but the links I provided discuss it in greater detail.

P.S. The No. 08 .22 caliber training rifle should be capable of shooting better groups. I would expect it to be capable of shooting groups of 3/4 of an inch or smaller at 25 yards.
