Great, enjoy the rifle! For elk i'd look to using the 338 or 348 grain powerbelts. Or even the 385 great plains bullet if she can handle the recoil. Its not bad bad but some people dont like the recoil of them. I used the 385 great plains bullet and 90 grains pyrodex RS last year and got decent groups with them and a great sized doe. Im also going to suggest the saber tooth bullets. But they have one flaw as i found out the hard way... When/if you carry the rifle upside down while u are walking on a rough trail, the bullet likes to fall out of its cup and onto the trail, and thats one hell of a good start to piss a hunter off lol. i believe
www.thepossibleshop.comcarrys the 245 grain great plains bullets. Cabelas also has 50 of the 245 grain buffalo ball-ets that shot very well out of my winchester. With elk, you'll want to use a heavier bullet so i'd really look into the 338 or 348 powerbelts. And possibly look into the new platinum powerbelts. Enjoy the rifle tho, they are very well built and quality of them is amazing. Where you from anyways?
