Hi Gang!

First of all, thanks to everyone here as my son and I returned from our trip to NAMIBIA a few months ago with great success...ALL the help I received here was very instrumental in making that happen wonderfully...You folks taught me well...FYI...I used our 30-06 rifles with...
180gr NP/54.3gr. IMR 4350/CCI 200 Primers that shot sub-MOA clover-leafs in my son's Sako L61R Finnbear and my Rem 798...

We shot 12 animals in all...(3) Kudu Bulls, (3) Monster Ory Bulls, (3) Monster Warties, (1) Blesbok, (1) Impala, and (1) Monster Hartamnns Zebra Stallion....

All one shot kills except for my second Kudu Bull that needed to be stopped with a 2nd bullet at 265 yds as he tried to trot up the high mountainside's ridgeline making retrieval even more difficult than it already was...hehehe
PH said hittem again...265yds shot and he was dead on his feet and tumbled down 30-40 yds from the steep mountain-side...OUCH...,Oooops!
But all was good!

Anyways again, nice to be back on this part of the forum asking help from the gang that knows best!

I need a lot of your expertise once again!
Okay, I can now successfully do the 30-06 and I expect the 270W will be the same...

But, what about loading for the 7 Rem Mag...

I should've also mentioned that I particularly want to be CAUTIOUS about CASE HEAD SEPARATION...

How do I effectively resize this cartridge to maintain the life of the brass...A year or so ago I read here that this cartridge is headspaced off the shoulder... So what is the understanding here?

Do I NS my brass with the LEE COLLET DIE for a couple times or so until I can't close the bolt on it, then BUMP the shoulder back a skosh so it can just close with a hint of resistance???

Is this the PROPER way to look at sizing this cartridge???

I'm at a total loss...


FLR?
P-FLR?
NS?

I have the LEE DELUXE DIE SET...
IMR 4350
WW BRASS

NO primer...recommendations please!


As always I appreciate the expertise and talent of this board and as I mentioned thank you to all that had made my first reloading experience a very successful one at the range and in Africa!....

Aloha!

Roland

For a 7mag I think you will be far happier with a slower powder. I like RL22, RL25 & 7828 using a 160gr.

I always full length resize hunting loads.

As to primers.....I use Remington magnum primers

nothing wrong with WW brass

Powder....probably nothing that burns faster than H-4831

+1 Functionality in a hunting rifle is much more important than that last little bit of accuracy.

Thanks guys I appreciate it!

If someone could address this it would be super and I shall include this in my original post to be more specific!

Thanks again!

Roland

I will definitely consider at least FLR my hunting loads as you mentioned VD...Thanks for adding that in here!

But, what about for practice stuffs at the range!

LWD, COOL...I got you on that too!!!

I read you guys loud and clear and I will most definitely heed that WISDOM...Thanks!

But...

What about at the range when one wants to work up a load and wants to get in bit of practice time on the rifle...Not the kind of practice to erode the chamber by any means...hehehe

Just looking at extending brass life...that's all...

I'll be happy with 3-4 reloads off the brass if its safe to do and being cautious by checking my brass???

What you think?

NS, then P-FLR?

Or just FLR all the time and discard after a couple times...

Just looking for the relative understanding when reloading for this guy!!!

Its just a LOTTA powder next to my precious cute face....

And its gotten my attention as I want to make sure I know what I'm doing here on all fronts!

I want to be perfectly clear on what I need to do with this Magnum...hehehe


Thanks!

Anyone to comment, please...

Sorry I thought you were asking about bullets and I missed FLR as full length. Sorry senior moment. What I do on belted magnum cases is first firing they headspace on the belt. After that I set my FL die up to just hit the neck shoulder. This changes you case from headspacing on the belt to shoulder. If the chambering gets tight just increase the bump slightly. DO NOT set the shoulder all the way back. As long as you keep it headspacing on the shoulder you will not overwork your brass.

This is how I headspace all my belted carts. Look to slower powders like H4831sc, RL22, IMR7828 & H1000 for best results in the 7RM.

Paul and Fred...

I'm SOLID and I got it now...thanks mucho mucho guys!!!

I appreciate it!

I am going down to get me some RL22 in a few hours!!!

Aloha!

LB,
Some of it depends on the chamber of your 7mm Rem Mag. They have a lot variation in length and diameter. I have one that is so large fired brass will not fit in a Wilson BR type sizer and seater set. Even if you minimize pushing the shoulder back the cases may still get a lot of sizing diametrally.

Thanks...I appreciate the heads-up on this...If I run across this problem at least I'll know what's happening!...

Gooooood gosh! Didn't you all leave anything for someone else?

Congratulations to both of you.

If you will be Hunting in Dangerous Game Country, then a person is best served by using FLRed Cases. One less chance of a miss-feed or a bit of trash binding the action at the least appropriate time. It does shorten Case Life due to Head Separation potential, but you Fire Form them, shoot once to verify accuracy and then Load for the Hunt. If you have a Flier during the Second Shooting, move that Case into the Practice Ammo Lots.

When preparing for the Fourth shot with those Cases(after Hunting with them), move them all into the Practice Ammo Lots.

Dosen't mean you should do your Practice Cartridges that way though. Here good old P-FLR is what I use. NSing is OK, but then you have to guess at when you need to do NSing so called Shoulder Bump. Haven't used any Lee Dies, so I don't know if you can P-FLR with them or not. I don't think their Collet Dies are designed to let a person P-FLR.

I rarely Hunt in Dangerous Game Country, so good old P-FLR works fine for the vast majority of my Hunting.

That will work fine for Practice Cartridges.

Seems like you are doing fine to me, especially on the Killing.

I like H1000, Fed-215s, and any domestic Case that has been Fully Prepped. Plenty of excellent Bullets available, just depends on what you want to Kill.

Congratulations again on all the fine Kills.

Why are you so concerned about case head seperation? I never had that problem with my 7 mag. The common practice is to use a very light bit of case lube at the base of the case when full length resizing, inspect the cases every time watching for the dreaded ring. If you are very suspect, you can use a single lot of identical brass and keeping track of the number of times it is reloaded, and cut a couple of cases open periodically so you can phisically measure the thickness. That is the best way I know of to guard against seperation.

Hey HC,

Miss you my friend and thought I'd come here to visit again before I try to reload for my only second cartridge ever to get some understanding!

I'm grateful that you chimed in as usual!

Yep, we shot'em all up and had a BLAST there!

Thank you for taking the time to share and I'm clear on everything and good to go!!!

Don't know either, that's why I'm asking...

As I mentioned I recall I read something here and couldn't remember exactly what was being discussed and since I'm a new reloader I just want to mahke darn sure my ducks are in order BEFORE I go on with this...

I appreciate you taking the time to post and I will most definitely heed your recommendations!

Thanks a bunch I feel even more confident now!

I have a batch of 7mm RM brass working on its 12th reloading. WW brass I load with Reloader 19. Sub MOA with Berger 168G VLDs a great game getter and accurate too. I do use a collet die for sizing the base of the bullet just ahead of the belt. After a few ( 5 or 6 ) loadings they will get tight just ahead of the belt.

Wow...

I just need 5 reloadings and I'm COOL...

But thanks for letting me know what is possible!

I don't mind buying brass after 5-6 reloads as I consider it rather cheap insurance especially that I'm quite new to all of this!


BTW, where is the "BELT" on this cartridge???


Thanks for sharing!

That would be the "widest" portion of the Case directly forward of the Extraction Groove. It is clearly visible in your Reloading Manuals and on the Cases.

Does it say 7mmRemMag, 7mmWbyMag, 7mmSAUM, 7mmWSM on the Rifle's Chamber and on the Case, or something else?

I've been loading my 7mags with IMR-4350 for the last 14yrs.I'm getting groups of 3/4" or less in two rifles.The chronographed velocities are 3200fps with 150gr bullets and 3240fps with 140gr bullets.I've had excellent case life,loaded many over a dozen times and very few cases have been discarded over the years.So I'd say IMR-4350 has been an excellent choice.
