Re: 300 win with 125 gr. Ball. Tip
Motivation, your barrel twist is probably a 1&10 twist. Your barrel will shoot the 125grn Ballistic tips, however, you will probably not get the groups you want. If your getting 3/4 inch groups you should be fine shooting coyotes. The 125grn bullet works best in a 1&15 twist barrel and slower. I am having a rifle built specifically around the 125grn Ballistic Tip bullet for shooting varmints out to 1000 yards. I will be using a 300-WSM with match chamber and a .333 tight neck. I will also be throating the barrel for the 125gr Ballsitic tip. Here are the specs;
1. 300-WSM with Match Chamber and .333 tight neck.
2. Lawton 7500 Action, 1.450 Dia. Fluted Bolt and Oversized Bolt knob.
3. Krieger 30", 1&15 twist, 1.350 tapered to 1.250 at the muzzle, throated for 125grn Ballistic Tip Bullets.
4. McMillan Tooley MBR stock with removable stud for Bi-pod use and 5lbs of lead added to rear.
5. Jewel 2oz trigger
6. Vias Muzzle Brake
7. Lawton 20 MOA Base
8. Nightforce 30mm Rings
9. Nightforce 8x32x56mm NXS with Double Dot Reticle.
10. Rifle will weight 25 pounds (Will be very stable)
I will be getting some awesome velocity and accuracy with this set up. I will be pushing the 125grn ballistic tip at 4000+fps. I am betting your barrel is about 26", so you should be pushing the 125grn BT with the 1&10 twist barrel at around 3650fps, that will blow a coyote in half. I know the VLD bullets are best for long range shooting, however, the 125grn BT has a BC of .366 and traveling at those above mentioned velocites makes it a very flat shooting rig out to 1000 yards. It will send ground hogs five feet into the air and evaporate them too. I will be shooting this rig at the smaller California ground squirrel. I can't wait to see how far it sends them flying. This is, with out a doubt, a Red Mist set up.
What kind of powder are you using for your load. I have been doing some reserch and it looks like Vhitivoria N550 is working well with this bullet. I will be able to pack about 75grn of N550 in the 300-WSM. I love the Ballistic Tip and V-Max bullets, they blow up varmints like no other bullets out there.
How fast are you shooting the 125grn Ballistic Tip. You might need to drop the powder charge and go for a slower velocity with the 1&10 twist barrel. Diffently get a good trigger job and if you have the $$$ and you want to shoot the lighter bullets, buy a Krieger, Lilja, or Lawton barrel with a 1&15 twist and add a Muzzle Brake. If you do that, I bet you get groups in the .4's. If you have the Action Trued, stock pillar bedded and do the other above mentioned improvements, I bet you get groups in the .2's. Your going to have fun with the 125grn BT once you get that baby shooting. Keep me posted on your progress.
