In January 2004, Land Systems was awarded a contract to develop a new smoothbore 120mm gun for the British Army Challenger tanks. Rheinmetall of Germany will provide examples of the L55 smoothbore gun fitted on the Leopard 2A6 for the programme. A technical demonstrator will be produced by 2006.

Reading some comments from former tankers, specifically a Master Gunner, one downside to rifling is the increased dispirsion of the explosion on impact. Thus robbing the progectile of some prenetration ability

Rifled barrels on the other hand, increases the 'lethal range' of a tank gun. All ammunition types are fired during exercises and 'range' shoots. This excludes 'war shots'. This ammunition is of a superb quality to standard rounds and because of this, the range can be as much as 6.5 - 7.5 kilometers, depending on ammunition. Chally 2 firing APFSDS can hit targets with ease out to 7-7.5 Ks. (Just over 4.5 miles to you and me)

Ok you guys may believe this or not, but when I was watching a show on the History channel out the Abrams tank they said can hit a target the size of a basketball form a mile away. Is the Abrams gun really that accurate?

AS for HESH rounds there really isn't any need for them these days, the Brits as far as I know are the only ones who still bother to use them. HESH shells have bugger all effect on modern tanks and have no greater effect than HE shells.
