Major Dooley Studying Effects 
of Cartridge Priming 
It is the priming that kills a 
rifle’s accuracy. The priming 
ordinarily used in rim-fire car- 
tridges causes the rifle bore to 
rust and pit. That gives the 
bullet a bumpy path from breech 
to muzzle and you can’t get ac- 
curacy under those conditions. 
Tests of every kind have 
proved that the recently devel- 
oped priming used in the famous 
N. R. A. 22 s and all other US 
Rim-Fire Cartridges eliminates 
the chief cause of excessive pit- 
ting and erosion. 
Of course the rifle must be 
regularly cleaned as usual. 
Be good to your rifle. Shoot 
US Rim-Fire Cartridges regu- 
larly. Your scores will improve 
and your rifle will stay in good 
condition. 
Money back if you’re not sat- 
isfied.
