great looking rifle,
and great caliber(I have 3, 270 WBY's
) I don't know what brand of after market stock it has, but as long as it fits both you and the rifle well, it looks alright.
After a thorough cleaning like that be aware you may need a couple of fouling shots before the barrel settles down. I would try the 2 you have now before getting the 140's. Good luck.
I agree with what Roger posted, also since your moving back to California, you might want to try the factory Barnes 130 gr TTSX load. I found the old factory 130gr TSX load, accurate in all 3 of my 270 Wby's.
If you dont reload, and just use factory ammo, keep all your once fired empty brass. With a little research, there are people who will buy Weatherby brass for $1 a piece, and it helps offset the cost of shooting factory ammo.
