I use 100gr heads with 75gr inserts.
The only issue for me since I have. 29" draw is if I shoot a 125 gr head with injextions it makes my spine a little iffy on the flexible side
Update #3: I'm calling Bull Schlitz on VAP - just measured my A/C .330 and it's .003" smaller diameter than their .250 and .003" larger than their .300 so I see no reason the Yellow Penetrator-2 insert/outsert from VAP would not work on an A/C .330.Update #2 - According to Victory the Injexion is too large OD to use with them????
