Need for speed with 25SAUM Imp

[SVT_Tactical]

Got a crazy desire to try to hit 4000fps + with my 25SAUM Improved. Think about using the sierra 70gr blitzkings. Sierra claims they are good up to 4400 fps. Barrel is a 10 twist and I've pushed 110s to 3600 with no pressure signs. Slightly concerned about blow ups. Anyone spun the blitzkings that fast before that can chime in?

Way over my head, but that seems to be a test of bullet construction, jackets, mfg process. I bet there is a type of bullet that holds together the best ?? Interesting line here. solid copper bullet for max integrity?

That will be a hoot no doubt. Back when Nosler brought out the 55 gr. BT we ran them at 4100 FPS playing around busting water jugs at 100 yds. Amazing how quick the jug explodes compared to the crack of the rifle.

I have shot 75gr Vmax from my 25-06AI that out run the 3900fps speed limit of my labradar. 10 twist haven't blown one up yet.

Should be okay. 4400 in a 10 twist is 316k rpm’s. I ran 100gr Nosler BT’s at 3600 in my 7twist 25sst (370k rpm’s) and only had one blow up out of a box of 100.
