.243 Barnes load data for 80gn ttsx

[heretohunt]

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.

Thank you for that. I have seen that and the loads I’m looking for are not there. Actually, I only have the one of those powders and it’s not great in my rifle.

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...

Did you try looking here:

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?

[heretohunt]

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.

No sorry nothing for the 80gr. Next closet one down was a 75gr TSX I believe.

[madcarpenter]

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

If you're not seeing pressure signs, I guess. But I would've started a few grains lower, and probably would not exceed ~42gr... If it were me.

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...

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

Brass dosen't generally show signs of over pressure till about 70,000+ /psi which is way over pressure. Velocity above what book maximums show is a sign of overpressure. Most of us without pressure testing equipment cannot tell what pressure value we are dealing with as we have no way to test for it. The best measure of pressure most shooters have available to them is velocity, if we are getting higher velocity than the books show with their max loads or higher than max load we should pay attention to it. It is good that rifles have a safety threshold built into them and won't blow up with overcharges but because they may not blow up dosen't mean the rifle will not eventually show cumulative damage like lug setback and metal fatigue if overcharges are continually used over time.

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?

Based on Barnes' load data for Reloader-17, which is closer to H4350 than SuperFormance, you're already 2 grains over max load and 50fps faster...

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.

Superformance is known to be hot, both their factory and their handload recipes. You didn’t list barrel length but 3446 is pushing it pretty hard unless you’re running a 26” barrel, even then….

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.
