has anybody, other than Buffalo Bore, been able to safely move a 155grTAC-XP in the 1400fps range?

Unless someone has verified Buffalo Bore's claims, I only
see them as "claims" and not fact. And whoever verifies
it cannot ask BB for free ammo for testing. They have
to be anonymous buyers.

I have not personally tested the Barnes load. I have tested the 180 gr. They claim 1311 fps from a G20. I averaged 1335 fps (IIRC, it was summer temps). Others have reported chrony results that are consistent with BB claims too. I have no reason to doubt their claims.

Now I wonder if that is too fast, check out this fragmentation @1200fps:

(same bullet, different cartridge)
However Cor-Bon pushes the 155's to 1200, and they seem like the kinda folks that may know what they are doing

Did you see the bullet fragments?
10mm Reloading Forum
This is what I was mentioning about over driving the HP type bullets, they open to their max expansion dia. then start to roll back on itself to a smaller dia. even shedding fragments, till it comes to rest.

So in therory, is it better to reach total expansion rather than over driving the projectile to the point it rolls back and/or sheds its petals?

This is the Barnes 140 grain at velocity as written by the picture...

I did, however this data kind of contradicts that test's result

A 155gr Tac-XP coming out of a .40 @ 1178FPS!?! now that is a hot load! I wonder who makes it

I have been a member for some time, however have not done testing for a long time. I am finally getting to do some.

I tried out some Vihta Vuori 3N38 with Barnes 125 gr and also Magtech's 130 gr CHP, and C.O.P. 140gr CHP's, and got some great results.

11.5 gr 3N38
140gr C.O.P.
col 1.250
Fed LP primers, Rem brass
6 inch L.W. barrel
1395 fps avg, es 15.
primers showing very slight flattening, but very little case expansion.

12.0 gr 3N38
125/130 gr Barnes/Magtech
col 1.250
Fed LP primers, Rem brass
6 inch L.W. barrel
1535 fps avg, es 12.
same as above, primers show very slight flattening, normal case expansion compared to Winchester 175gr Silvertip.

Definitely not 'full' power, would have been 100-110 fps less with a 4.6 barrel, but still decent.
