I'm looking for a supplier of .461 bullets for my trapdoor.I checked several pages of bullet makers and the biggest I have found is .459. I shot 15 rds of .457/.458's and it was like patterning a shotgun.I used some .461 the 1st time I shot it and it shot real well.They guy I get these from does not have any more and doesnt remember where they came from. thanks...
