Yup. Can't use the Tula stuff at my range

Why not?

They don't allow bullets with steel therein. Sparks. That's their
story, and they're sticking to it.

From http://en.wikipedia.org/wiki/Wolf_Ammunition (Same factory makes Tula and Wolf)

Steel-jacketed bullets[edit]
In addition to using steel casing, certain types of Wolf rifle
cartridges use steel-jacketed bullets, which are often copper-plated and
cosmetically similar to standard copper-jacketed bullets. The copper
exterior of the bullet is approximately .005 inch thick, with an
underlying steel jacket of about 1/32 inch thick. This type of
ammunition is labeled "bimetal". Indoor shooting ranges, which use
backstops often constructed of steel, have accordingly widely prohibited
steel-jacketed and bimetal ammunition to prevent shooters from damaging
their backstops (as well as steel to steel contact from the round
causing sparks, which in just the right environment could ignite unburnt
powder residue in the air).

If there is enough unburnt powder residue in the air that it might
ignite, I would not enter that room without a respirator.
Until the recent anti-tobacco fad, you could smoke in most indoor
ranges. Lead is a much bigger issue in an indoor range.
I would believe they think you are hurting their bullet trap tho. I am
not sure you really would. If that is their fear, they should be
banning magnum rounds and just about anything out of a rifle.
Only 2 things ever made a mark on my 1/2" steel plate backstop.

One very hot 125gr .357 round (1725fps)

A factory .44 mag from my carbine.

That was the only CF rifle round ever fired in there.

There was a gun shop in San Leandro, CA some years ago who had a fatality
from a round going through the wall behind the range. The bullets had worn
a hole in the wall. Might be the driving force on steel bullets. Lots more
erosion. Was Traders Sports.
