Was just wondering what opinions everyone has on how tight to pack the bags and what sand are you using. I started out shooting BR 50/50 25+ years ago and I am using the same bags today with a Hart front rest with one of their original windage tops. I have my bags packed so tight you couldn't get another gain of sand (zirconium) in if you wanted to. My rear bag is a Protektor Model A(? bag is so old I can't read the mod #) short bunny ear. I have been shooting F-class for about 3 years now and I have seen some pretty loose bags. Some aren't even packed with sand. I saw one guy who packed his with walnut hull.
Best regards,
Grit
