It’s probably that crappy .25 Boss.

. It just takes a while - I've shot 228 with that gun. I’m in the low 220s on average going in to EBR with the .25 Red Wolf HP shooting Mk1 Heavy at 950 fps. Shot a 233 last weekend (no flags) but it was fairly calm. Best to practice in swirly conditions. Learn to shoot a few sighters then directly to a target or two. Rinse and Repeat when wind looks favorable. I never shoot when the wind switches to the opposite direction of the prevailing direction. That’ll get you in trouble in a hurry. Most times you have about an 80/20 split wind direction when shifty. Don’t shoot the 20. Just wait.

PS., if you're just shooting for high score, shooting five 5 shot groups will make you feel better, but won't really prepare you for EBR. To get in good EBR practice, shoot one target, then the next until you've shot all five, then go back and do that again four more times. In my experience, the difference in score is about 4 to 5 points lower when shooting "competition" vice "group" style..
