Try this
1. use a dry mop and some alcohol and clean the bore of factory oils etc.

2. Bore sight the gun

3. go to the range and shoot a three shot group in the matter of two minutes or less.

4. Adjust the scope wait ten minutes and take three more shots.

5. Use a coppersolvent and clean the bore thouroughly.

6. Take a five shot shot group and ignore the first two shots and again adjust the scope. You should be " on" by now unless your gun just hates the load you' re using.

7. Take another 5 shot group and clean the gun

8. Clean every ten rounds until you' ve fired 40 rounds and then every twenty rounds for the lifetime of the gun.

This is a minimum break in routine.....yet it' s a 1000% more than most guns get, and it' s not overkill for something that has no real confirmed value.

Good luck with a fine gun
