I am new to the forum but already I like it. I am proposing and an interesting thought. I have a 300 Win that I am trying to set up for coyote hunting. Now I know that this is not the taditional coyote set up but I don't get the traditional shots. I am looking to do some long range shooting with as much knock down power so that there is as little suffering as possible in the event of a off center hit. That being said I have loaded some 125 grain nosler ballistic tip bullets for my 300. I am using it mainly because I like to shoot and parctics to improbe my effectiveness and don't like the brutal recoil of the heavier bullets. My problem is that the rifle is not shooting to my expectations. I am getting about 3/4 of an inch groups and would like to get at least to half inch.
My question is does any one have any experience loading these lighter bullets? Is this typical for a 300 sendero. Is there any tips to making it shoot better. Besides the obvious trigger job.
Is there a better accuracy load you can turn me on too!
I suspect your barrel has the standard 1/10" twist which is geared more for 170gn and up bullets. 3/4" group isn't much to worry about. When I first discovered this board, I was into faster, lighter bullets. I have since discovered the error in my ways. Bullet drop is easier to calculate than wind drift...Just my thoughts.
I have a 300 WSm and I loaded 110 gr v max in it. I tried 4 test groups of five shots each and five different powder amounts and all shot between .5" and .75" I have a Tikka w/ a 1 in 11 twist. I used H380 powder.
I used to re-load but now I "hand-load".
-- Well, at least I try --
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.

with the barrel twist this rifle probably has what would be the best bullet to use for long range coyote sniping?

Unless it's a custom ordered barrel, it most likely has a 10:1 twist (called a 10" twist).
There are those that think a light bullet can't be accurate in a fast twist, but that it not true.
Many people that have twists as fast as 7" shoot very light bullets with great success. Plus the higher rotational speed will cause the bullet to make much more impact damage on arrival to the critter!
You might try loading the bullets to touch the rifling - that will do a lot for accuracy.
I shot a 300WM for long range varmints for a while, and used heavy bullets (178 A-Maxs). I thought they were good at first, and they were accurate, but they often punched through the critter, and then they bounced around the north forty.
I went to 110 V-Maxs and they are like a hand grenade, and even when you miss, you won't get bullets bouncing around - they come apart on the first dirt they hit. They will lift a large woodchuck 3 to 5 feet in the air out past 600yds, and tear up a feral dog or yote something awful at 1,000yds!
You can do very well with the 125 BT or the 110 V-Max.
