Can you test at a further distance, such as 300 yards? It'll likely tell you more than at 100.
Also...I'd suggest ditching the lead sled. Nice rifle! Should be a great ELR rig. |

View Quote I can redo the ladder test at 200 or 300 on Saturday, take those results, then reload and shoot the groups on Sunday. ETA: What is wrong with the lead sled? Is there something better to use for testing loads and correcting POA/POI when the time comes? |

Cool rifle. The first magnum caliber rifle I shot was a .308 Norman mag. I think it was a Parker Hale. Damnit man that was a long time ago. I think I was so scared I missed the target so bad that bullet is still going. Then I figured out it wasn't as bad as a 12 gauge with heavy magnum loads. Next round was a little high and about an inch left.

With the brake that is on there it kicks a tad harder than a .308 to my best estimation. So after the first shot I was like "Hey, that wasn't so bad". |

The best way to look for nodes IMO is run you ladder test over a chrono. Does the same thing as shooting at 300, but gives you the data.
Im not a big fan of lead sleds either since they aren't a normal shooting position or recoil pattern. |

I got it at the Costco.

Thanks for the responses guys. I am new to all this and I appreciate the help and tips. I have a hunting trip to WY coming up in 1.5 weeks and I planned on this being my primary firearm. I will do as much as I can to get this done properly.

Any idea what the std dev. was for the loads?
Did you tune out the parallax? Noticed that the groups shifted around. If it wasn't you, it could be a parallax issue. |

Looks typical for a well set up 300 Norma Mag, with the bullets going to sleep and the groups staying pretty tight at longer range. Nice set up.

Lol, 3100 fps from 230otms
Mine are 2300fps and 2400fps for single feed out of my .308win. So envious of your velocity. Supersonic to about 1900yds or more. |

Slightly off topic...how do you like that Vortex?

The heavier the bullet, the longer it takes to settle down. Does it take hundreds of yards? Nope but the heavies can take 100-150 yards to get there. View Quote Please tell me what force is changing the flight path. The bullet is heading off to the left at 1/2moa(1moa total), now supposedly the bullet "goes to sleep" or stops wobbling basically and then changes directions and starts heading to the right to end up .165moa(1/3rd moa total) left. What caused the direction change? Why didn't it just continue on its path from the point of stability? I shoot 230gr otms in my .308, 147s in my 6.5, 90gr smks in my .223 I have never experience group convergence. |

The nice part about being a pessimist is that you are constantly being either proven right or pleasantly surprised.

I took my 300NM and 6.5C out to WY this past week while I was out hunting. Both shot extremely well and had accurate shots out to 900 yards.
