Winchester Brass. CCI LR primers and jumping then. Don't have my book on me to tell you exactly how far but it is a fairly good jump

I'm baffled , what rifle ,custom ,factory , thks overly tight chamber .
It's a savage 11. I would think the same thing but I have tried probably 6 or more other bullets in this gun with no real issues

I'm running the 80 gr ttsx over h4350, .050 off in a 22" barrel @ 3278 fps. Can't remember the exact charge but used the same chart you posted in #6 Poe. Shoots better than any other bullet I've tried. Possible carbon ring? Copper builds pressure differently than cup and core. Sorry if I missed it, but are your cases trimmed and sure the case mouth isn't jamming in the front of your chamber? I'm baffled. Sorry, I got nothing.
Simple problem of using to much powder for an all copper bullet.
Is this the correct bullet? Barnes #: 30208?
I would use Hodgdon data for the Barnes tsx 85 gr., when loading your 80 gr ttsx bullet.
If you read history on Barnes early bullets, they caused many reloaders to experance dangerous high pressure problems and copper fouling , when using data for lead core bullets. At the time , Barnes had no data of there own.
Barnes redesigned the bullet by putting many grooves on the bullet.

Hodgdon lists 14 different powders for the Barnes 85 tsx. The data can be used to load your 80 gr. imo.
IMR 4451 produced the highest velocity. Wonder how accuracy would be?
I use IMR 4350 & IMR 4831 in Win brass with Br2 primers and Berger 68 & 90 hpbt match bullets.

He's either undercharging the case, not seating the bullets deep enough (or too deep?), or he has a rifle problem peculiar too Barnes bullets. I think the slightly reduced loads for the original x bullet went away with the TSX because they have reduced friction from less bearing surface and hence Barnes states you may need to increase powder charge 1-2 grains compared to lead core bullets to get same velocity or you can push them faster. It was the same in the past with their XLC blue coated ones, of which I still have some, compared to the standard x bullets.

Not sure if IMR 4350 and H4350 have the same burn rate (see post #1 & #6). Also, have you ever "slugged" your bore? Perhaps your barrel is a smidge on the tight side. Do your cup and core bullets hit max published MV before max charge weights. Your MV seems on par if not abit high for a max load.

40.5-40.7 max, hmm...
