7mm Rem Mag suggestions
 
Hey All,

Just got my Lee 3 die set for 7mm mag. My reloading experience is limited to .45 ACP and .40 s&w. When I started to reload those I got some starting point/recipe suggestions from my Dad and friends to narrow down the trial and error of finding the right mix. While I still try new mixes for those I am looking for some of the same advice for the 7mm mag. Gun is a 700 cdl and will primarily be used for norcal pigs and deer so I am looking in the 139-150 grain range. Wont be in the lead free zones for a while so at this point any info as far as lead bullets brand/type/weight and powder brand/loads would be great. I have a reloading book and will be checking all suggestions with it as reference but I dont have the cash to try all the options it lists at this point and could use the advice......

Thanks

I use 140gr Nosler Partition and have found that they are great in the 7mag. I also like the Swift 140gr A-Frame bullets or the Hornady 139gr Inter-Bond bullets.
I have a lot of load data I have worked up over my chronograph. PM me if you want more details on loads.

Got to Hodgdons.com in the reloading data center and check out the starting loads using H4831 for the weight bullets that you are using.

Thanks guys. And yes please Divernhunter, I will take you up on that offer soon.

I use H4831SC. I do not run that many rounds thru my 7, so bullet cost is not that big of deal. I have had my best groups ever with 175 gr partition, but the less expensive 150 gr ballistic tips were very close.

In my 700CDL, 140gr Nosler Accubonds and Hybrid 100v have been a great combo, generally 1gr under Hodgdon's listed max. For the heavier bullets, look at Retumbo. It has given me the best velocities with the 160s and 175s and for some reason heats the barrel far less than any other powder I've tried.

joe, a wee bit heavier than what you asked, but, this has worked very well for me on oinkers and Eastern Sierra mule deer.
154gr Hornady Interlock flatbase, 63.0gr Reloader#22, Win. cases and Fed LR mag primers. MV avg is 2950+. And is ACCURATE. You may wish to try this bullet at least.Good luck.

Now I load 7x57, not rem mag, but I do love the 7mm caliber. Great bullet. So based on readings I trust, it looks like THE bullet you are looking for is the 160 grain Nosler Partition. Or, the 150 or 160 grain sierra game king.

I suggest this for reading:

I think 4-5 out of the 6-7 bullets suggested here are recommended on that website for either <150 lb deer or piggies/mule deer. A couple for both.

Barnes 150 gr TSX HP boat tail
WLR Mag primer
60 gr IMR 4831
COL 3.325 .040 off rifling
2897 FPS

I loaded the lead free out of necessity since I was pig hunting in Cali.
The Barnes outperformed anything else that I fired through my Browning X-Bolt. WARNING the projectile will exit a 300lb pig at 230 yards. Stay away from nickel cases with the all copper projectiles, it seems that nickel cases require a little give that the solid copper bullet won't provide.

Great info guys thanks. I picked up a few different powders and bullets this weekend in my travels from the gun show in vallejo, bass pro in manteca and old west gun room in el cerrito. Got some nosler partition, sierra game king and hornady in weights ranging from 140-175. Didnt see any barnes around but Ill grab some of those when I get a chance. Looks like I've got some reloading and shooting to do but I need to find primers first. Might have to just break down and order them online if I dont find them soon.
