Wow! Excellent choice, you have two very accurate guns right there! I have a HW44 and it’s very accurate, and I always find myself wondering how good the rifles are if the pistols are that good. Good shooting!
I have the BP-K in .177. Great gun. Dead accurate at 50 yards with Polymag Shorts. Sighted it in today with 12.5 NSAs at 25 yards and so far it's looking good. Lookup "Hunting with Hardman" on YouTube, he does a great review on it.
