.243 Barnes load data for 80gn ttsx
Could someone please look up some load data for me in an old Barnes manual. I’m looking for the 80 grain TTSX data for 243.
H4340 and Varget loads specifically but other options are alway good. I am hearing some conflicting information and thought it would be best to go to the source. It seems like the current online data is pretty limited. Thank you. |

It’s a wicked little bullet. Push it fast and accurate. It’s my current go to 243 bullet.

It's not from the Barnes manual, and is for the 85gr TSX, but maybe helpful...

Thank you fish. That is a good start.
Thank you also to parttimeHunter somehow that site doesn’t seem as helpful now that it’s been changed. |
Here is the data from the Barnes #4 manual. Hopefully the pic is clear enough for you. :)

Thank you. Is there anything for the 80 gr TTSX?

Here is some feedback if anyone is interested.
Of course, I will give you the disclaimer that this is in my rifle and I will not be using it in my other one without working up. If you choose to use this data, you should do the same. 243 Winchester, with 80 gr TTSX, Coal. 2.61 inches, federal 210 primers, Winchester, brass, and h4350 I started at 40.5 gn and got 3023 ft./s. I carefully worked my way up to 45.7 grains with no pressure signs. The speed there was 3446.4 ft./s. Probably I will be using 45 grains as it looks like a promising node. |

The 80gr load data is on their web page. It’s been updated.

I used the load data on the superformance cannister..approx 3500fps and accurate

I say this because of the data for the 85gr I posted, and the data on Hogdon for the Hornady 80gr GMX (which has almost identical S/D and coefficient as the TTSX). And ~3450 FPS is really pushing it with an 80gr... :scared0015: https://i.ibb.co/rdhmN0x/Screenshot-...019-Chrome.jpg |

I love that rifle
Imr 4064 and Varget were my favorite powders. Have fun and show us how it groups!

I ignore most pressure signs except for velocity and bolt lift- if you have hard bolt lift, you are already over pressure for your riflle no matter what the books say as far as data goes .

That’s good to know. I am at Max velocity with H 4350 of what the superformance recipe says. I may try to use the Satterly method with superformance and see what comes out of it.
One of the problems I’m having is that I don’t seem to get a consistent low extreme spread however I am definitely well under MOA at 100. Since it’s likely only a 400 yard rifle and under should I worry about the es? |

Maybe go back and try some lower charge weights than what you started with ? See if that improves your data. |
I have found that most load data is a guideline and it varies as much as 4 or 5 grains depending on the source of the data, your rifle will tell you when you have reached max. Most manuals will tell you to start 10% below max and work up slowly.
At the risk of dating myself when I started loading back in the 70's before the internet I mostly used a Lyman manual and it was pretty hot on the top end of most cartridges. IMHO the old rule of thumb still holds, go slow and if the bolt is sticky your maxed out back down, there is not an animal alive that will notice the difference of being hit with a bullet doing 3400 and the same one doing 3325. |

ES could also be a neck tension issue. Only way to know if it will be a problem is multiple groups at 300-350-400. |
