It is not a known statistic, however for USBC, you can compare the list of names of who bowled a 300 and how many bowled an 800 and then how many of those who bowled an 800 had a 300.
I am part of a bowling team and i dont know many people who have bowled a 300/perfect game. i do know a few good players though and i have seen people bowl 300. x
70
yes he had made a 300 in the year of 2000
Jim Hosier has bowled 112 perfect games in his career.
Yes.
225
hello gutter, hello fadder
As of 4-13-2015, the number of 300 games Bob Learn has bowled is 115.
In the United States, that is Fran Lasee who was 89 years old when he bowled a 300 game in January, 2010 at the Willow Creek Lanes in Green Bay, Wisconsin. Click on the 'Oldest US 300 Bowler" link below to read the story.
Unfortunately there is no way to know this number precisly. USBC has a record of all sanctioned 300's in America, however this do not include 300's bowled for fun or practice or in unsanctioned leagues and tournaments, or before the establishment of USBC. So theres no definite answer.
There is a very long list of bowlers in the IBHOF who have bowled a sanctioned 300 game.
