Salt cure for venison jerky

[Mossyoakglock]

I wasn't sure where to put this.

 

I am in the process of making some venison jerky from a deer I got last weekend so I need to get some salt cure. Most of the recipes that I've found online call for InstaCure No. 1. I can't find it anywhere locally and don't want to order online if I don't have to.

 

I did find A.C. Legg's locally and wanting to know if they are both the same. Both are 6.25% Sodium Nitrite and 93.75% table salt. Being that they have the same makeup I would think they could be used interchangably but wanted to check first.

 

Anybody here cure their own venison and know if they are interchangable?
