Nope...not me.Is the question, Is this rifle a tack driver?, or is the true question, Can the shooter drive tacks with the rifle?.... ????
If a person can shoot well with iron sights then lighting has to be right to shoot a one hole groups at a hundred yards.I have never found much eatable meat on tacks, so have little use in driving them anywhere. And I never won a shooting event driving tacks. Found them best suited, if used, to hold a target place. The tacks never seem to be in the scoring zone. But I have had, and still own one 54 caliber GPR flintlock with a L&R lock that will create a ragged hole at 50 yards with 5 shots, and a group in the inch or so range at 100 yards. Really seems to depend on lighting and how well I see the target, likely brought about by my born on date.
