150 NBT 7mm-08 Experts - 24hourcampfire

What's the go to powder for this combo? Thinking Big Game and H4350.

Thanks,

I've got a great load using 41.0gr of Varget, Fed 210 and Hornady brass. I shoot it out of a M70 Fwt (22"). It's only about 2675fps, but groups really well.

R17 has treated me well with 150 BTs in the 7-08. Mule Deer's Chapter on the 7-08 in the Gun Gack Book listed the same load as I've been using with nearly same velocity.

My favorite loads in acouple rifles is 43.0grs of Varget with the 150gr ballistic tip

RL17, Big Game, or W760 work well with 150/154. The plastic tips eat up case capacity when loading to 2.800 OAL, which hinders getting enough H4350 in the case.

Whatever shoots best. My 7-08 preferred H4350 over Big Game or Varget.

Lots of good advise above.

I'l also consider Imr-4895, RL-15, and CFE-223:

Brad curious if you had any crony data, guessing that was your 22" Kimber? Temp? Thanks.

I think the 150 BT is a gem in the 7/08......... I see Noz now makes the AB in the 150, should be a nice combo, though at these speeds on impact the 150 BT may be very similar on game. I may be the exception, but would likely prefer the AB to a PT.

I've had great luck with reloder 15 and h380.

I use Big Game but my 150 is an eldx. Elk and deer don’t have much time to argue, they’re too busy tipping over. 2790 or so.

Thanks,

Here's what I use! Big Game powder! My 7-08 loves the 150 NBT. Of course it likes RL-16 as well...

Hodgdon is showing some pretty fast velocities with the new StaBall 6.5 in the 7mm-08. Anyone tried it yet?

I’ve not chrono’d it but 40.5grs of H4895 shoots really good from my LVSF with the 150 NBT.

For those using big game, are you using regular or mag primers?

Tula LRM for me

WLRM

fed 215 mag with 140s

My 708 experience with 150s was with the Sierra MKHP, used the suggested accuracy load in the manual and it shot very well. Great accuracy above using newer powders, and solid speeds. The 150s are often overlooked but deserve more use, especially on larger game and/or longer ranges. Good info.

40 grains of IMR 4895 kicks ass in my 7-08 pushing the 150 gr. Ballistic Tip..

Reloader 19 worked well with 140’s in mine.

I would recommend WLR or WLRM for lowest velocity spread with Big Game in 7mm08; my primer test results below.

7mm08, Kimber, 22", 140 Sierra ProHunter, 2.800", Lapua brass, 47.5 grains Big Game, 65F

Code

1	2	3	Average	spread	Primer
2,866	2,862	2,909	2,879	47	Rem9.5
2,858	2,875	2,888	2,874	30	Fed210M
2,871	2,878	2,864	2,871	14	WLR
2,833	2,839	2,869	2,847	36	CCI200
2,892	2,903	2,905	2,900	13	WLRM
2,856	2,857	2,879	2,864	23	CCI250

The first CCI200 was a slight hang fire.

46.2gr H414 over 150gr Nos CT was a great shooting load in my 7-08. 2.840 COAL

Hi 65, my load of 46.5 H4350/210M/Nosler Brass was 2,700fps on the nose.

I agree with you on the NBT, it's really quite a bullet.

The best loads I found in my last 7-08 with the 150 NBT (all 210M) were:

46.5 H4350 @ 2,700
42.0 Varget @ 2,717
45.0 RL17 @ 2,730
49.0 Hunter @ 2,745
