7mm Rem Mag Recipe

[elwaynum1]

Hey guys,
I am new to this forum as well as reloading..I just purchased the Lee Challenger Breech Lock Single Stage press as well as the deluxe set of 7mm Rem Mag dies along with the factory crimp die. I do have the second edition of Modern Reloading by Richard Lee as a reference but would like to know if have any of you all have a recipe for a round that can be used for whitetail hunting up to 300 yards as well as just messing around shooting targets and what not..
I'd like to keep costs to a minimum in terms of bullet selection and other supplies so any help would be greatly appreciated. Thanks!

Good budget all around 7mm bullet... http://www.midwayusa.com/viewProduct...tNumber=514256

64 gr IMR 4831. CCI mag primer. Close to 3000 fps out of 26" barrell.

[NUKE HUNTER]

i use those same hornady bullets with 58 gr. of IMR 4350 and cci mag primers. they group nice out of my 24 inch barrel. didnt get to try them on any animals yet though.

[williamd]

For years I have used 60 to 64 grains of H4831 behind a 160/162g bullet. Magnum primers (CCI/Winc). Great stuff. I like Hornady and Nosler bullets but that is a personal pref.

I drop to 139/140g bullet for 7mm (7x57) adn 7mm/08.

[oneounceload]

The most accurate bullet in my 700 is a Sierra 160 BTSP; however, my favorite hunting load is a 160 Nosler partition. 4831, 7828 or 4350 will all work well. You will want to try some different bullets and powders to find what works well in YOUR rifle.

[ojibweindian]

150 grain Remington Core-Lokt, 60.7 grains RL-19, and a Winchester large rifle primer. Groups average around 0.72" at 100 yards and perform well when hunting deer.

[elwaynum1]

As far as mag primers go, how do I know when I need to use them? Does it mention whether or not I should in some reloading manuals?

I have been building (3) 7mmMags on Mauser actions this month and working up some handloads in them.
Here are my load notes.

Hodgdon web site:
162 gr HDY SPBT H4350 3.290" 58.0 gr 2799 fps 49,400 CUP

62.8 gr H4350 162 gr interlock moly 3.34" Quickload estimates 26" barrel 65kpsi 3085 fps [measure 3040 av]
65 gr ok 72kpsi 3176 fps
66. 5 gr ok 78kpsi 3238 fps
67.5 gr easier primer insertion 82kpsi 3279 fps [stopped work up because of change in the brass]
67.0 gr ok difficult primer insertion. [says 80k, 3259 fps discounting 1 gr for chrono feedback, 76k, 3218 fps]

I need to load a lot of ammo and leave for hunting.
The safety margin I subtract off the 67-67.5 gr threshold will be between 2% and 6%

The Quickload prediction is off by a grain. I must have a slow batch of H4350.

When I correct for that, then the threshold of long brass life is between 76k and 80k psi, which is about what one would expect for a magnum case head. Stronger than a Mauser case head, but weaker than a 32S&W case head

[TheNatureBoy]

This is one that was given to me so I'll pass it on to you. I've been very happy with it.

62.8 grains RE-22
Sierra 160 gr. SBT
Nosler 160 gr. Partition
Fed 215 lg. mag. pri.
Winchester case

This is my favorite load. I use it with my 7mm Rem Mag Sendero.

[oneounceload]

As far as mag primers go, how do I know when I need to use them? Does it mention whether or not I should in some reloading manuals?

My manuals show using a magnum primer with this caliber; it also seemed to be a good idea when hunting in cold country for a better ignition

[GeauxTide]

145gr Speer Grand Slam, WW Cases, CCI250, 69gr H-4831, 3130fps

154gr Hornady SP, WW Cases, CCI250, 67gr H-4831, 3007fps

I found any standard bullet of 145 and lighter were bombs and made a big mess above 3000fps. 154 and 160 standards work fine on any deer.

[plainsman456]

I just got done loading for 2 7mm mags and the bullets i used was the 140gr rem coreloct.I tried rl-19,rl-22,H-414 and imr 4350.I went with imr 4350 63.0grs.The man went hunting in new mex and slammed his antalope between 200 and 300 yards by just putting the crosshairs on hair.Good Luck

[thekyrifleman]

69gr H4831 140 gr Sierra pro hunter, Rem 9 1/2M primers, Rem Cases.....THIS IS OVER MAX IN MODERN MANUALS.....started using it in 1966. Gives about 3000 fps in my Rem 700. Excellent accuracy. Also use 66gr RL 19, 140 gr Nosler BT, Fed 215 priimers, Rem cases. 3050fps..this duplicates the Rem factory load for velocity. Under one inch at 100 yds easily.

__________________

Being that I have never loaded for the 7 MAG. its new to me. I loaded some 160 Grain Sierra Boat tails over 60 grains of H4831 with CCI Large Rifle Magnum Primers. My old Hodgon manual said 60 grains was about the starting load but the new Hodgon Manual (more like a magazine) says 60 grains is the max for that bullet. Have not shot the rifle yet or that load yet. According to what williamd and some of you have tried, it looks like I might be ok with 60 grains of H4831. I will be trying the rifle (Model 700 with a 26 IN. Barrel) in a week or so. I am hoping that it will be a good whitetail deer getter.

[elwaynum1]

I'm not too sure about using the Nosler BT's. Are they going to expand too much for a thin-skinned whitetail? I'd like to try and conserve as much meat as possible.

[thekyrifleman]

have killed at least a dozen whitetails with the BT and one caribou in northern Quebec. All were through and through at ranges up to 200 yds. Have also used the BT in the 7mm Shooting times Westerner with excellent results. Muzzle velocity was 3425 fps. Same results.

[troy_mclure]

i got some 175gr swift sirrico 7mm spbt that are just BEGGING to be pushed up past 3000fps! lol

oh, ive got the same press, and its treated me good from .32acp to .45/70.

[ZX10Aviator]

what Im using

70gr Reloader22
140gr Barnes xxx
Magnum primer

3292fps on the chrony

[James R. Burke]

For a freind using his rifle I worked up a load for him. Large mag primer, IMR-4831 and a Nosler 150 b.t. I tryed to get him to switch to a bigger partition but he is sticking to the first ones I worked up for him. I believe Nosler now makes a 160 partition for the 7mm mag but not sure. If they do I would give it a try. For deer I been using partitions on my wifes .243 and my 30-06, they work great. They cost a bit more but I feel it is worth it. That is just me. There are many good deer rounds you can use that will work just has good or maybe even better out of your rifle. I know my freind with the b.t. has dropped on the spot every deer he shot at with it. But for deer I myself like the partition better. Just me. Make sure you have a few manuals. The more the better, nice to cross reference with etc. I always try to have the one for the bullet I will be using.

[DKA]

I use 160 Gr Nosler Accubonds and 72.5 Gr H 1000. Fed Magnum Primers. About 3045 FPS.

[preventec47]

I am now liking lighter bullets in the 7 rem mag and last year my
load was the 120 gr Pro hunter bullet with 65.5 gr of Hodgdons new
Hybred 100V at 3327 fps

This year I am moving lighter and using the Barnes Tipped TSX 110gr
bullet over Reloder-17 68gr powder for 3535 fps.
This is for deer and the Barnes bullet is plenty tough enough
The real gift here is the greatly reduced recoil. Will make you giggle
if you have been shooting 160gr all your life.

[gun44]

pushing a Speer 145gr btsp, to 3100 FPS. According to the Speer 13 manual this is actually less than their starting load, which is 68.5 grs, with a max load of 72.5 grs. However they are publishing just 3181 FPS with the maximum, and, according to my chrony, I am getting nearly that with just the 68 grs, so I see no need to increase the load. Great accuracy as well with less than 1/2 MOA @100 yds! Great round for my rifle.

[preventec47]

GUN44- I think you made a big mistake in your manual data.

Alliant who I think is in business with Speer, has as their data
for Speer 145 gr bullets max loads as follows ( 7mm Rem Mag)

RL-17 = 61.8gr for 3113 fps
RL-19 = 67 gr for 3153 fps
RL-22 = 68 gr for 3136 fps

The indicate this info with 24 inch barrel.

I just want you to have the correct info.

I dont necessarily think you are in danger because I think the
7mm Rem Mag can handle the same pressures as other
belted magnums like the Weatherby instead of the
downloaded SAMMI pressure which is the same as a 30-06
which is 4 or 5 thousand psi less than .270

It's almost as bad as the 8mm Mauser downloaded to 30/30
power levels.

[Shorthair]

I have a pet load that I find very accurate in my rifle. This load has accounted for many one shot kills over the past 20 years. I've chrono'd it right at about 3050 fps. Use caution, load may not be safe in your rifle, other lawyerly statements should be considered.

Remington case
68 grains of H1000
Federal 215M primer
Nosler 150 grain Ballistic Tip

I have at times used the 150 grain Partition to great success as well, using the same recipe. If you hit a deer in a front shoulder with any bullet you're going to damage quite a bit of meat, but in the heart/lungs the BT is deadly. I've actually recovered them, the deer this year I hit at 300 yards stopped the expanded bullet under the skin on the off side. The buck dropped dead on the spot, so the lack of an exit wound really never concerned me.

[gun44]

you are absolutely right. I was looking at the 7mm WEATHERBY magnum info, when posting the info! Sorry about any confusion. The MAXIMUM for the 7mm Remington Magnum IS 68 grs! Thank you for correcting me! I have been reloading for a long time, and this just proves once again how we all can make mistakes!
