One of the ranches I hunt on sights in with lead sleds (they have no sandbags) . I can’t get it out of my feeble mind that it seems to cause my rifle to intentionally shoot a tad higher.
I’ll sight in at home 2” high....sight in out there and I’m 7-8” high...a little more than expected. Makes me glad I have a McMillian stock on my #1 rifle, as I definitely feel they could bust a walnut stock on a “kicker” easily.
Give me sand bags.
