Thread: Rifle Double Grouping

Double grouping is commonly caused by poor bedding or uneven pressure on the barrel. 3 shot groups are not definitive a 5 is much better. I had this happen with a Zastava with a plastic stock. The stock warped in the back of a ute due to heat and touched the barrel, so I free floated it thinking it was a good idea. It had shot ok before but after free floating turned to shit. Turns out it was pressure bedded. Had to do a bedding job with accraglass to get it back. Worth it though now shoots 3/4 in off a sandbag at 100. Also agree loosing the bipod is a good idea, they bugger the balance and are useless when quick shots present themselves.
