CaptC, I am having a custom .30 cal varmint rifle built specifically to shoot the 110grn V-Max and 125grn Ballistic Tip.
It is called the 300 Varminter and is built by Richard Fraklin of Richards Custom Rifles.
The 300 Varminter is based off the 300 WSM cartridge and is a match tightneck chamber. With a custom action and a 30" 1-15 twist barrel, it will push the 125grn BT at 4000+fps, and the 110grn V-Max at 4100+fps. Look at his web page and check it out. It is an awesome set up and barrel life will be much better than the 300 RUM. Plus, Norma makes excellent 300 WSM Brass.
I am having it built to shoot Pdogs and ground squirrels out to 850 yards. The 300 Varminter is absolutely devastating on varmints. If want a .30cal for shooting light bullets at 4000+fps, I would highly recommend you look at the 300 Varminter and Richard Franklins web site.
Here is what I am having built;
1. 300 Varminter
2. Nesika Model K, 1.470 Diameter Action
3. Bartlien 30", 1-15 twist, 1.250 straight cylinder barrel
4. Richards Model #8 1000 yard stock, with 2 pounds lead added
5. Jewel 2oz trigger
6. Vias Muzzle brake
7. Nesika 20MOA Rail
8. Burris 30mm Signiture series rings
9. Nightforce NXS 8x32x56mm with MLR Reticle
10. Weight of rifle, with scope, will be 22.5 pounds
It's very important to understand that a regular 300 WSM will NOT come close to pushing the lighter bullets at 4000fps. The 300 Varminter is a specially designed rifle. Proper componets, such as custom action and a 30" 1-15 twist barrel, must be used to obtain 4000+fps.
There is also an article on 6mmBR.com about the 300 Varminter. Check it out!
