Metau, sounds like you got yourself a great rifle. You can't go wrong with a Remington rifle. When your financial situation is better, you can customise the Remington action almost as good a custom action.
Reloading information, try this load;
1. Brass-Norma 300 Winchester Magnum
2. Powder-78grns H4831
3. Federal 215 Match primer
4. Nosler 180grn Accubond (.507 BC)
5. Velocity with 26" barrel will be around 3200fps
He uses this load for ELK and Mule Deer with great success out to 600 to 800 yards. Start with 74grns of H4831 and work up to 78grns. My friend uses this load in his Remington 700 Sendero, and he gets 1/2 inch groups at 100 yards. The .30 cal 180grn Accubond has an excellent BC (.507) and it anchors animals quickly.
For varminting and long range varminting try this load;
1. 84grns H4831
2. Federal 215 Match Primer
3. Nosler 125grn Ballistic Tip (.366 BC)
4. Velocity is around 3650fps out of 26" barrel
Start with 80grns of H4831 and work up to 84grns. My friend uses the above mentioned load out of the same Sendero. He loves this load for long range varmint hunting. When he hits varmints, with this bullets, it is absolutely devastating. It is also very accurate out to 1000 yards. I've have watched him use this load, and rifle, for varmint hunting and it made me want to design a rifle specifically around the 125grn Nosler Ballistic Tip for long range varminting. However, I am going to use a 300-WSM with a 30" 1-15 twist barrel which will allow me to push the bullet at 4000+fps.
You made a great choice for both Long range big game hunting and long range varmint hunting. Try the above mentioned loads when you get a chance and let me know how they work for you.
Also, you will be happy with your Burris scope.
I remeber my first long range varmint rifle. It was a Remington 700 ADL, chambered in 7mm Remington Mag. I bought it in 1991 for I think $450.00. My scope was a 6x20x40mm Nikon Monarch. I think I paid $400.00 for the scope. Total set up with ring and bases was right at about $1000.00 too. I used a 140grn Nosler ballistic Tip and shooting it at around 3300 fps. I have been hooked ever sence. I remeber guys, back then, looking at me like I was crazy for using a 7mm Remington Mag for varmint hunting. And know I think I was on to something back then. Anyhow, like I said, I was hooked.
Have fun, and keep us informed on how she shoots.
