7mm08 Remington guys.. help

[Archer79]

So I just acquired a Tikka T3 in 7mm08...I wanna use it this weekend in Ny deer opener...give me your favorite load recipe let me know if I'm in the ballpark....I'm using 139 sst bullets and H4350

Cant help with 139gr but if you wanted to try some 162gr SST's my load for them is RL-15 at 38.2gr with CCI200 primer and seated at .030 jump. In my 24 inch Shaw barrel this load will hold 1 1/8 -1 1/4 at 300 yds. Easily making consistent hits on steel out at 750 yards. 39.5 grs of RL-16 also does really well.

139 gr Hornady Int with 39 gr H4895. About a decade ago I took a speed goat & a hog with it in my "Salvage" model 16, both dropped in their tracks. I played with RE-15 & 17 but stuck with H4895 since I had a decent pile of it.

Varget and RL-16 have worked well for me recently. I’m loaded between 2.930” and 2.970” depending on the load, so charge weights may not correlate if you’re at saami length. RL-16 has a nice flat .5 gr node around 2900. Varget is about 50-70 fps behind. Both with 140 NAB/NBT. 150 gr NLRAB at 2800 with RL16. 140 gr Hammer AH at 2910 with Varget.

This combo worked way better than it should in a 26inch 10twist
Lapua Brass
BR -2
IMR 4064
140 vld

44.0 grains of Reloder 16 and a Hornady 154 grain Interlock bullet touches each other at 100 yards out of my mountain rifle. Has dropped every deer I have shot with it. No wondering, no tracking, no kicking and flopping, no B.S. just dead right there. Best of luck!!!!

Thanks guys all good info so far....I loaded 48.5 of h4350 with a 139 sst (it's what I had) I'll let you know how it shoots...my dad is taking it to the range today while I'm at work(stupid work...lol)

I think 4350 is too slow for 140 class bullets in the 7-08, at least it was for me when I tried it. I haven't done any work on my 7-08 in yrs since I worked up a hunting load and loaded 60 or 80 rounds for it (last basically for ever)

I'm running 140s at ~2900 with 2000MR.

Isn't 2000mr even slower burn than H4350?

H4350 with a 139SST, or 140gr BT is perfect.
The 48.5gr seems a little high to me.

With how long of a barrel?
Not a 22" hunting barrel, your not!

 

[XTR]

24" barrel on mine.

Yeah, that might be bit hot!

47.2 gr is where I'm at with 140 Bergers in my son's Tikka after a ladder test for powder charge working up.

22.4" barrel...50 is max in hodgdon manual 48.5 I get no bolt lift at all 50 it was ever so slight

What case are you running? Using Lapua, I had to use a drop tube when approaching 48.0 gr. It was pretty da*m full! At any rate, sounds like you worked up and know where your max is.

Peterson brass...it's really full and I'm using a drop tube and a slow pour...I haven't worked much with the 7-08...so I'm not sure how it'll shoot...it seems like most guys are using something like Varget with a 140 class bullet

That is the problem I had with H4350 was that I couldn't get enough in the case to get the velocities I was looking for at the time. I haven't worked on loads for mine in 7 yrs or so. At the time I had some left over 2000MR from my experiments (ok, more than an experiement, I shot up about 20 lbs) in F-TR with that powder. It wasn't temperature stable enough for long range F class but it will give much higher velocities than Varget w/o pressure, and these days it's usually available.

Isn't 2000mr even slower burn than H4350?

The burn rate of 2000MR is faster than H4350 but I think slower than Varget. Alliant 2000MR is much finer so you will have no problems getting to max velocity with it (just don't try to over do it). The only issue with using 2000MR will be that it is very temperature sensitive. Temps for my hunting season can be sub-freezing to 65 degrees and I want first shot kill zone impact every time. From competition with 200MR in the past I will say I had to deal with day to day impact changes that were not at all what I would want for my hunting rifle.

I didn't see the variations being bad enough to be a problem for hunting. I shot up about 20 lbs of the stuff about 6 or 7 yrs ago. When I ran the powder in F-TR it would shoot tiny 300 and 600 yard 5 shot groups, but 20 shots on target at 1000 yards I'd get 3 to 6 high flyers in a match. When it pretty much cost me a shot at the state championship I went home and did some more detailed research. Running some long strings over the chronos I figured out that I was getting the occasional +20-50FPS load. At 1000 yards shooting at a 10 inch 10-ring that translated to a dropped point. At 500 yards with a 140 gr 284 it's about an inch and a half. If you are shooting ground hogs I can see it maybe being an issue but on deer it's never been problem.

I thought about the new 6.5 staball powder it seems to get really good velocities in the 7-08
