I was just being an arse, you may find out of the rifle at least likes the projectiles but if you plan to change brass and powder i'd wait before going much further.

At the end of the day (in the words of @R93) do what you want, you will anyway

Will definitely be changing brass but likely not powder....ironically I was talking to Dave last night

If you're getting lovely little groups and a 3fps spread with Federal, what have you got to gain?

Very fair call.....Sometimes a reality check is what's needed....I do love to tinker, sometimes to my detriment.
There is nothing wrong with the 2209 groups thats for sure I guess it was just too easy.
I am not a fan of the federal brass due to the primer pocket inconsistencies, its all once fired but some felt a lot looser than others.

Hi Danny I'm using Laupa brass in the 7-08 I'm working a load for at the moment.
I'm using 2308 and 150 ELDX from a 20" Tikka seated to mag length.
I did a ladder last night and went up to 40.6 with that giving me 2726fps but a slight stamp and some weight on bolt lift.
I've loaded 10 of each 40 and 40.2 as both were around 2675fps and showing no pressure. So I'll shoot them for groups when the rain stops probably tomorrow night.

Looking at Quickload, 2209 isnt a great choice, you will be @ 108-110% fill rate, hence the crunching powder. You are only at a burn rate of 90% in the 17" barrel, and the velocity isnt as high as you could get with a few other powders.

2206H gives much better fill rate %, far higher burn rate, and far better efficiency % and higher velocity.

H414, CFE223, BL-C2 and Re17 are all better again in all those regards (if you can find any of them of course)

Also, don't forget projectiles such as the old school softpoint Sierra Gamekings or Prohunters or the Speer's. When i first started Handloading i used 130gr Speer Hotcors, only doing 2800 fps from a 22" barrel, but man were they accurate and performed extremely well on deer/goats, every single animal i shot with them fell over very quickly. Ive found these simple older bullets shoot very very well and with a decent sized lead soft point they also expand and perform very well.

I still use Sierra Gamekings/Speers as a mag fit load in my 284 and 7mm Saum. But I appreciate at these times, you gotta use what ya can find.

In all reality with a 17" 7mm08 intended for close to medium range you dont really need anything else.

+1 for hotcors. 145s in 7mm are vicious and found really easy to get shooting well. Crap bc as flat base but inside 350 doubt you will pick it

Granted pretty much any soft point would do the buisness and whilst this rifle is predominantly 0-300ish yard rifle I'd love to have the confidence to stretch it further should the situation arise.....is 450-500 yards asking too much ftom a short 708 ? The figures suggest not.
The golden phrase being "should the situation arise" not "this is my new long range hunting rig"

Yeah if it holds enough velocity and energy and precision out to 450-500 you should be fine should the need be there one day.

With my 15" 708 pushing 140 nbts at 2720 fps it holds in excess of 1800 fps and 1000+ ft lbs to 500 yds.

Ive practiced out that far with it and validated my drop data and would be happy to take a shot in the right conditions if the situation arrised.

@dannyb

For you're rifle I'd use ADI's pistol data.

The reason it's based off a 15" barrel


The 7mm08 for a rifle is based on a 24"barrel


Albeit they dont have data for the 150gr Eld X.

I used the data for the 162gr load for my 160gr TMK out of my model 7.

COAL of 2.780
40.0gr 2208

Mv 2430fps


Hope this helps

Very interesting, until today I had no idea a 7mm08 pistol was a thing

Yep sure is

284win is also chambered for single shot pistols.

Or 270 pistols with 12" barrels like the the remington XR100 series.

We use em here for Metallic silhouette shooting but stateside they can use em for hunting in their handgun seasons.

Norma brass Danny.
