Thread: 7mm magnum

I have a couple of questions for anyone running the 7mm magnum in an 85 sako with a 24 and a bit inch barrel.

1- Do you have any trouble with the 162gr Amax in the 9.5 twist.
2-If so what works for you.
3- What accurate speed would be likely in this rifle with what powder with the Amax or whatever you are running.
Thanks.

No trouble with the 162 A-Max, I think the rifle was made especially for them

Your magazine will have an internal length of 3.736 inches.
The overall length of your 162 A-Max load can be 3.460 inches (Or very close to this length) for a just touch.

72g of ADI AR 2217 will give you 3050-3080fps.

You can use all these projectiles with 72 g of 2217

A 140 NBT @ 3.385 inches long
A 150 NBT @ 3.385 inches long
A 150 E-Tip @ 3.420 inches long
A 160 AB @ 3.426 inches long
A 162 Amax @ 3.460 inches long
A 168 VLD @ 3.472 inches long

Federal 215 primers and Norma/Nosler brass work well, take the expander ball out of your FL die and your groups should shrink.

If you are so inclined anneal the necks and shoulders of your brass after each firing for consistent neck tension, moly powder lube the case necks and projectile when assembling ammo.

Use a comparator when measuring your ammo when seating the last 5 thou, a micrometer adjustable seating die ensures they will all be the exact distance from the lands.

Deer will fall at your every shot...... well nearly


A-Max damage

Just get it Owen. You know you always always wanted one.

Nothing?? I have something against Buying new guns when you're not fully using the ones you have. Which has stopped me impulse buying many things.

Yup. I wouldn't. I don't "get" collecting particularly.

It's fine if others want to I guess but I just don't get it. I keep seeing things and going "ooh man that's cool I want it", then I think "wait, I would never use it" and I don't buy it.

Thats not very 'CUB' of you Gimp

(Implying you are a CUB)

My post thanking you you for that information has dissappeared 7mmsaum [ or I did it myself somehow] so just incase you didn't see it.
Thanks.

No worries Jakewire, the rem mag is nice to carry around, good horsepower for Sambar too !

I just got one, its a cheapie. (Zastava) I like mauser's. Will 2213sc work with 140, 154 grain projectiles?

nor-west, yes it will, the ADI powders reloading Handbook has data for 2213sc and a 140 grain projectile.

It shows a minimum load of 61g for 2840fps and a maximum load of 64g for 2950fps.

For a 154 grain projectile a minimum load of 59 grains for 2775fps and a maximum of 62 grains for 2895 fps.

Nor-west, the little ADI powders reloading manual can be purchased online ($4) and at most good reloading component stores, they make extremely good reading and I have lost count how many times I have read it from cover to cover

Noslers reloading book 6 and onwards and Hornadys books are exceptionally good also, well worth the buy price, they would make great forum prizes, the more of these reloading books circulating among us the better.

If you have trouble finding one nor-west just let me know, I will find you one for free.

Yep I have one, it's back in NZ, those speeds are only slightly faster than my .280 is doing with loads that show no pressure signs at all, so maybe I need to get some 2217 powder just for the 7mm mag?
Jeff

Yes


Berger Bullets have just released their new reloading manual, its worth getting.

http://www.bergerbullets.com

OK I think I saw a container at Upper Hutt gunshop, I dont think it's hard to get, yep I need to get a couple of current reloader manuals, maybe a Nosler and Berger, um do I need magnum primers?
cheers
Jeff.

How are you getting on with the 7mm rem mag Jakewire?
