saber tooth is not available in .45 and if it were, i would not use it! A 50-60 grain charge would not expand it enough. A 250gr .50cal saber tooth only expands to the size of a dime 100 yards with 80gr RS.
For a child, a 195-223 platinum or 225 Aerotip with 60gr RS would be a perfect load out to 100 yards.
223 plat and 275gr will do great with up to 90gr RS. The 275 is a hard bullet for me to stop in my trap.
bow,
This is a 225gr Aerotip .45 Powerbelt that i used on a good size doe last year and put it directly through the shoulder.
When i got home i weighed the bullet and it weighed exactly the same as a new 225gr bullet.
This load was 80gr Triple 7 3F. Thats roughly over 100gr of RS for comparison.
225 is a real winner and a darn good deer bullet!
