loading 7mm mag

Post by Member-Deleted » 13 May 2018, 12:35 pm

G'day gents ,
Can anyone lead me in the direction of getting load information for the berger 168gr vld in 7mm mag
I have looked most places on the net and can't find any precise info
I ended up working up a load @ 69gr of ar 2217
Last weekend I run into a bloke that said that was too much ADI ar 2217 powder for those bullets
This has me concerned as the vlds run very accurate lightly touching the lands so i'm a little worried about pressure spikes
everything looks good with no signs of pressure
So some written info on min/max powder charge on these 7mm 168gr vlds would make me feel a bit better
It's strange I couldn't find anything on the berger site either
Thanks for any help in advance :thumbsup: :drinks:

Berger have gone the route of wanting to sell load information. A bit rich if you ask me as they are just reprinting what has been given to them by others.

I have just put into quick load standard information for 7mm rem mag with a 26" barrel,69gr of adi 2217, 168gr berger hunting vld, oal 83.57mm
the results were 2970 fps @ 57010 psi, max is 61000 psi
this info is not exact as you need to input more precise info that if you want I will do for you
IMO if this load is working for you use it, your not a silly man and know how to check for pressure :drinks:

let me know if you want to do a better quick load ballistic analysis :thumbsup:

Yes Sungazer that's the block I got from berger to pay up or nothing



Duncan61 , yes mate I remember having a chat with you about your rifle and loads awhile back and thanks although i'm not really
chasing another load just trying to see if i'm running safe with the one I use now 5 shots cut into 1 clover leaf hole @ 100yds



G'day Marksman, mate with the load I have now I am getting 2950 fps over the chrony so I am presuming I would be within the confinds
of being safe judging from your 2970 fps @ 57010 psi
My rifle is exactly as you have it only my bullet seating is a little longer but I don't think that would matter that much unless the were jammed into the lands
thanks this makes me feel a little safer , i'm not sure we have to go any further as it looks pretty well within the safety limits with what you have shown me

thanks all much appreciated
cheers

Hi grandadbushy

I may be of some help to you. I have the Berger reloading Manual.
Berger do not list AR2217 powder but looking at the ADI equivalents H1000 is listed as an equivalent.
Berger state for H1000 powder in the 168gr Berger Bullet.
Use this as a guide. You can also check with ADI.
Start 62.5gr approx. 2669fps
Max 69.5gr approx. 2987fps
approx. Fill Ratio 100%.
Once again start at the lowest and check your pressures as you go

The Berger Book is not that expensive I got a copy for $48.00.
Everything in this small Gun Store are very reasonably priced here in Adelaide.
They have a Web site and do take orders from Australia wide.
eg ADI powder $47.50 others here want $52 +
If they don't have what I want they are always happy order it in for me and have never been ripped off either.

Thanks bones-350 for the info and yes I started at 66gr and found my load at 69gr of ar2217 and that will do me as I get excellent accuracy
And yes there are some good little shops out there, I have an ADI manual so i'll use it as a reference for now but will get a berger manual later
Thanks all again

Grandadbushy just as a matter of interest I also have a 7mm RM what is the barrels twist rate and what sort of groups are you getting at 100ysrds thinking of using bergers in my 7mm also.

Yeah bones-350 mine is sako roughtech range 26'' barrel 1-10 twist
It handles all bullets well up to 162gr but does handle the 168gr vld bergers very well ,the 162gr eld-m gets the same accuracy as the vld's but
the 162 eld-x has less accuracy like .75 @ 100yds but it won't handle the 175gr they didn't want to stabilise no matter what I done so I gave
them to a bloke with a 1-9 twist and he loves them he's getting almost the accuracy with the 175gr as i'm getting with the 168gr vld but he hasn't finished
load development yet
The 162gr was supposed to be the max weight to stabilise in a 1-10 but many in the USA and AUS found that the vld 168's would shoot
so I tried some and found they do
I've put this pic up before but this is the accuracy i'm getting from berger 168gr vld 5 shots @ 100yds
I don't know if I move around to make my groups small but on the weekend I was getting a 11/2''-2'' group @ 350yds with a 25knot wind
at 90 degree

By the way bones-350 some have said that the 168gr vld would shoot well away from the lands but I haven't seen that but I have seen a few shoot on the lands and they shoot well ,mine are on or just in the lands but if I move them away from the lands the further out the wider the group although the widest group away from the lands was 11/2'' @ 100yds
Just something to ponder mate
