Zircon sand "heavy sand" is made to pack into molds. And if youve ever seen a sand cast mold it packs and holds shape like concrete. Thats the last thing you want in a sandbag for shooting but to each his own. I hope everybody uses it
I just used zicon in the front bag this past 2 weekends, on sunday I am the heavy varmint grand aggregate MONTANA state 2014 champ.
this weekend past (a couple of days ago) I am the canadian super shoot 2 gun winner,
in montana I also got the 200 yard small group
in canada I shot a .173 agg in 100 light varmint, a new range record provincial (state) record and it is being measured for the benchrest shooters canada canadian record,
SO DO NOT BELIEVE ALL YOU READ ,try it for yourself,
what they are not telling you is how to fill the bag, how to form the bag, how to try different distances where your stock overhangs the front bag, how the bag keeps it shape and how the ears are held into the stock (I shoot a JTR stock (my design) with high sides (mmm similar ot the new kelbly stock, wonder where they got the design), and it rides the bags better with a hard packed zircon and the bag is formed to keep the stock under recoil,
not saying they are wrong but try it for yourself, you may be suprised, and it id difficult to get any front bag where it works all the time but mine does quite well and I shoot not type,
just saying for some it will work for the masses stick to middle of the road advice, even speedys article on front bag and sand is not all correct as it
DEPENDS ON STOCK DESIGN BAG FULLNESS REAR BAG HOLDING THE STOCK STOCK DESIGN AND SO ON ,
not just the one variable of bag hardness with zircon,
question do your ears contain the same firmness or is the right ear stiffer???? and how stiff do you fill the ears and HOW TIGHT DO YOU CONTAIN THE STOCK, the JTR design allows the grip to be qite firm yet lift the gun out of the bags under the current nbrsa rules, does yours then there is the difference in design and function nuff said many will dispute as they do not yet understand
