Ok, the short version on my 10ga BPS ......experiment .
I used to go to Arkansas every year to hunt ducks ...and one year we had an option for Geese. My preferred duck gun is a Browning 12ga O/U ...so I took that gun as well (this was 20 yrs ago ??) So, I purachased a new Browning BPS 10ga just to take for Geese...figuring I needed the extra shell ...and I was 6'5" and a svelte 250 lbs in those days ( not old and fat, like I am now )... I probably paid about $ 600 for the gun / and an extra 32" barrel as well as the stock 28" barrel it came with / so call it a $ 900 investment ( with a hard case ). I put one box of shells thru it - at my local Trap range ..and figured I was ready !!
We were in our pits on our backs at sunrise / covered up ... as the guide yelled, Get Em -- I raised up, spotted a good Goose ...tracked him, leaned back a little since I was on the ground - following thru - and pulled the trigger ...and my head promptly bounced off the frozen Tundra ....and as I bounced back up ...I carefully looked around to see if anyone noticed ( and they all did ) .... probably because I swore loudly as my head hit the ground ( and my buddies were all laughing so hard, at least 2 of them had to get up and take a leak .....before they could go back to hunting ...). Now, not being a quitter ...I shot that 10ga for the rest of my trip ...and before I left, I sold it to the guide for about $ 400 as I recall - gun, both barrels, and the hard case. But I flew home with my limit of Ducks and Geese ...( and my 12ga O/U ).
And the morale of the story...a 12ga will do everything I need to do with a shotgun !
Kind of like when I gave my son 3 cases of Remington Nitro's ( factory shells ) 1 1/8 oz, 1300 fps ...a few months ago for a day of Trap, 5 Stand and Skeet .... and all I said was here son, you and your buddies shoot these for me, will ya, and don't drop any empties, I need the hulls .... ( and then I load them with 1 oz, at 1225 fps ) because I'm nobody's fool. He's not a bad kid ( he's 31 ) ...but its his mother's fault ( the ex wife )...that he's a little slow ....
I almost feel bad ... so next weekend, I'll only give him one more case of them to shoot up...
