Hello sir. Just registered this morning here. I agree w/ you on the BSAs. I just received my R10SE from AOA last week. I did a few mags after cleaning the barrel, which was the cleanest barrel I've ever received in an airgun. I then referred back to HAM's tuning video of the R10. I turned the hammer spring in to stop then backed out 5 turns , re-shot the string then another 1/2 turn out. This morning I got 4 mags worth of several 15 & 18(av) pellets w/ air to go before refill. I'm impressed to say the least ! Velocity was spot on to claims along w/ most any ammo working for pest duty to 40yrds. I noticed a rew weeks ago the R12 is on the Gamo USA product list. That is on my bucket list now! BTW, I had to get a rifle case to secure the R10 in (yet affordable) so I picked up a hard case at Harbor Freight , perfect !
