Im looking at doing a new load for my Swede using 140 Game Changers and RL19. V6.0 of the Sierra loading manual only has data for the 140 Match Kings.
Can I use the same data, as a starting point?
Cheers.

Greetings @taupo_cowboy,
Yes with caution. The Game Changers are described as a tipped Match King with a stouter jacket. The last may increase the pressure slightly so start with the start load to see if velocity and hence pressure are similar.
GPM.
What GPM said, I’d just run a simple ladder test to see where you are at and go from there.
I’ve just got a load sorted in my K95 with them and AR2209 at 2770fps

yes you can.....like ANY load data for ANY rifle..you supposed to drop down a bit and work up...I havent bothered for years,infact the only time I have...it possibly saved my sight as was wrong powder and blew rifle up.... so not such a bad idea the extra couple of grains couldve made things much much worse.
you dont have that worry,you using known powder,known rifle....you will have idea where in loading scale your rifle likes.....eg most happy as pig in pooh couple of grains below maximum book load. load up 3 and see how they go.... if all things look mild happily up charge somewhat,if they group tighter than a fishes bumhole...consider leaving load as it is....or at least going back to it if higher charge not as good.
we makes things way more complicated than need be.
Really unreliable projectiles on game, heaps of success stories and also a lot of stories of failures mainly not opening up. Ive shot two deer with them, one with 270 140gr at about 300yds behind the shoulder shot, stoned the deer on the spot and when I got to it about ten minutes later it got its second wind, got on its feet and took off down into a gully never to be seen again. One with 308 165gr shot directly in shoulder quartering on so exited the ribs on opposite side, deer ran good couple hundred yards before expiring, very small wound channel and tiny little exit hole.
As a general rule Sierra use the same charges for the same bullet weights. All the 140gr bullets will have the the maximum charge (cartridge, and powder dependent of course).
