Shot fall out

[roughshooter]

I was asked a question today and I do not know the answer so will ask the more knowledgeable members!!!

I know the fall out for lead shot is 250 meters but what is the distance for steel?

A pretty accurate empirical formula for this is 1500 divided by cube root 'n' where 'n' is the number pf pellets/oz.

 

Edit: Sorry, forgot to say - that's in yards.

Steel is probably less, like for like.

Under 200yards for #6 steel.

_{I reckon steel 4 will only travel about 200 yards.}

[Continental Shooter]

it depends on the speed at which is fired; however, as said, still will cover less distance than lead

 

if you want a relatively exact clacualtion you can use Lowry or Journee's tables

Thanks guys

The empirical formula was derived around No 6 lead and equates to 232 yards. It was only intended as a guide as there's no input for MV. Ballistic tables (Sierra Infinity) for MV 1300 ft/sec suggest 231. For steel using Hull Cartridges' version of No 4s similarly give 258 for the Empirical and 253 from the tables, again with 1300 ft/sec. So, not too shabby at all, but it's worth noting that if you wander too far away from the No 6 then the accuracy does suffer.

 

Edit: To correct a minor mistake. But while at it, if the 1300 is deemed too slow then at 1600 ft/sec the range of the No 6 lead will increase by a massive 7 yards and the steel 4s by an enormous 6 yards.
