You don't have to break the bank to try out your first coated loads.
You can buy as little as 100 bullets in 115 or 124 grains .

My first target load test with six different powders with a 125gr
coated bullet had a difference of just 19 fps in all the loads but...

the groups went from 1" all the way up to 2.66" and one that I
logged as a "Shotgun" grouping. (SG)
It took me a lot of loads and time with different OAL, fps and bullet
dia. (.356-358) to find out what my pistol liked.

They MAY or may NOT work out for you....
good luck.
