120g 7mm-08 Load data?

(typo in heading - 120 grn)

I have a bunch of 120 grn Sierra that I want to load as a duel wallaby/deer load and use up powder that is not "precious". Mainly wallaby - but I see the odd good deer that are often out of range for the .223. So if Im in an area where there are deer I will take the 7-08 for the day instead of the .223. Thats the plan.

I usually use CFE.223 or BLC-2 for 120 NBT on deer but don't want to waste either on wallaby.

So, what are good loads for 120 grn with 2206H or 2208? They are the powders I have surplus?

18" barrel and would like to get close to the 3K I get with CFE223.

Thanks

Sounds like a job for Gordon's Reloading Tool! Do you know the water capacity of the brass you're intending to use? Have you measured the maximum cartridge overall length with that bullet in your chamber? With those two bits of information and the data libraries I can work out some suggestions about likely outcomes.

I know the OAL but the brass is a mixed bag (using up my mixed brand stuff). I will look up the OAL. Ta

Depends on which gun your shooting the 7mm-08 out of.

In a mates T3 we run 43 gr AR2206H with Remington brass.

The same combo in my kimber is too hot.

I played with Remington brass but had better luck with PPU so I run 41 gr AR2206H

As you point out CFE223 is good powder in the 7mm-08 so I think you’ll get higher velocity with that powder.

I really should get some more and give it a whirl in the 7mm-08

I would have thought your .223 firing the heavier projectiles would be the ducks nuts for what your planning

The 223 shooting the 77 grn is the ducks nuts on deer but swapping the magazine from the cheap 55 grn to the 77 when I see a good deer is a pain and takes time.

The two 7-08 I load 120 Nosler ballistic tips in with 2208 I think one uses 42 grs and the other 44 but I'll check tonight they both do 3000fps

I run a 120ttsx load at 43.5gr 2206h. Cant remember where it was on the charge weight spectrum but it was pretty mild i think. 17" tikka, dpt can doing 2970fps

My Rem 700 Titanium shot very well with 120s over 47gn 2208, charge seemed about sensible max.
22in barrel, clocked around 3080. Also accurate with 120s and 45gn of 748 or 4064 but a little slower
than 2208, around 2950.

44.5 gn 2208 w 120 NBTs

@davhope

My old 20" t3 loved them 120 NBTs, used 45gr 2208 av 2996fps and super accurate

Just stick with shooting roos down here,problem solved.:thumbsup:

Fat chance :) :)

;)

45gr of ar2206h through Tikka 20" gets me 3070 with 120 seira prohunters. Using Winchester brass

16inch Kimber is getting 2830 with 45gr of 2208 behind the 120BT. 46 got to 2900 but is over book max and accuracy dropped off. I tried Belmont 760 up to 50gr but only got close to 2700 with the short barrel. The 45 of 2208 seems the sweet spot in my rifle.

@Tahr, chainsaw's post earlier is pretty close to what I was using for Sierra 120gr Pro Hunters. 14 inch barrel length my side...

Either 2208 or 2206H would work fine.

@Tahr Greg Duley did an article on hand loaded 120-130gn from the 7mm-08.
I think I still have it, will check the bookshelf tonight.

Found it, but I'll scan it tomorrow at work. As using the phone camera sucks.

I thought 2206h and 2208 WERE precious lol

I picked up some imr 4895 a while ago, before the shortage kicked into gear. It's going well with the 120 vmax in my Tikka T3 and I'm at 43.5 grains, seems to be right around where most of you guys are with 2206h.

Not sure on speeds as my chroni was playing silly buggers today, some of my shots were over 4000fps somehow apparently :pacman:

Thanks for all of the replies.

I tried 45.5grns 2206H today. No pressure signs. Grouped .5" for 3 shots. Velocity 2904fps (18" barrel, Sako A7). That will probably do it. I could go to 46grns but hardly worth it for say 30fps just to push the envelope.

Wondering if you loaded to mag length with these?

No. 20thou off lands.

I wasn't happy with the chrono results (Labradar) from the 45.5gr load with the 2206H so re-ran them today with an increase of .5 to 46 grains.

Much better. I must of had something set up wrong last time. I got a consistent 3k from the 18" barrel today, no pressure, and nice .5 -.75" 3 shot groups. Very happy.

@dogmatix did you ever scan that article as I’m interested?

now to find some cheap 120grn projectiles of any sort,in bulk,preferably soft...speer maybe??? and them wobblies wont know whats hit them.

Tried the 120 sierras in my 18inch m700 in weekend. Had 42 grains of 2206h and was at 2800fps. Good accuracy so think I'll leave as is, could possibly go a grain or so higher and see how it goes
For reference PPU 120 hollow I chronod at same time done 2800fps aswell, these are very good factory ammo, highly under rated, great for 40bucks a box

Just play with seating depth now and that will be a mint load

@Forestry Sorry, didn't manage to do it on the work copier/scanner before the office closed.
Can do it just with a camera though.

I hope Greg doesn't mind re the IP, as its a 2009 edition, so long out of print.

Perfect thanks - 47+grn of 2208 with a 130gr load is pretty up there but he is measuring the impact on the case so well controlled

He also got a lot of 2209 in a 7mm08 case !

Thanks @dogmatix that was an interesting read.

I got given a heap of old NZ hunter mags, hopefully that series is in the stack

120gn Nosler BTs and 50gn 2209 is a load that has worked extremely well across several T3s and a Mod 7. Norma brass. I even used 140gn BT with 50gn 2209 no problem but approach that with usual caution. Consistent 0.5-0.75 MOA.
