To change the firing pin on a Remington Target Master Model 41A, first ensure the rifle is unloaded and safe. Remove the stock by unscrewing the screws, then take out the action from the stock. Locate the firing pin assembly, usually accessed by removing the bolt; unscrew or unclip the old firing pin and replace it with a new one, ensuring it is properly seated before reassembling the rifle. Always consult a gunsmith or the manufacturer's manual for specific instructions and safety guidelines.
Minimum range would be the end of the barrel. Maximum effective range for a M-16 firing the dimensionally similar 5.56x45 is listed as 550 metres at a point target, and 800 at an area target. For a rifle firing commercial .223 Remington ammunition, you could expect the results to be similar.
