Gets the lead out

justwannano;

...have a Rem. 512 Targetmaster, single shot .22. Rifling is weak, ran some lead-a-way patches through it, showed some improvement. I suspect there is still quite a bit of lead in the bore, do you think the vinegar and peroxide will do the job?

...a friend has offered some Mercury but I'm a little hesitant to try that.
