G20 ammo question

[ii open]

Lately me and a buddy started to go to the range at least once or twice a week for about a month now and I always shoot my g20 (about 50rds each time).  My questions is: Is it safe to shoot full power ammo all the time?  I have shot at least 200-300 rnds so far.  My g20 (gen3) has an aftermarket barrel, ss guide rod, 22lb recoil spring. 

Ammo I'm using:
Reloads
-200gn bullet
-9.6 gn blue dot
-starline case
-winchester wlp primers

Thanks

Your ammo, as loaded is fine for everyday use...
