I use my HFT 500 and cleaned our club 50 shot BR target with a max score of 5000 three times out of 4 shoots before covid put pay to things!
I fill to 150 and do half the course and refill after the first 25 shots to then complete the course of fire.
Same with HFT I fill to 150 which covers our 30 shot course. This gun is so ultra consistent at that charge weight. Was thinking though of getting a dedicated BR stock for her as the standard stock is not totally ideal.
Cheers
