7mm Magnum loads

[Buzzsaw]

Got a pretty M70 Super Grade, 7mm Magnum. Going to work up a Nilgai load. Any suggestions??

partition
A-Frame
Barnes LRX

I don't have any H1000 or Retumbo

Do have:
RL-26
IMR 7828ssc
H4831sc

Working with 150gr ballistic Tips and Berger 168gr Game Hunters

You can never go wrong with H4831 in a 7. And those 150 Ballistic tips are what I shoot in mine. You could go to a stouter constructed bullet, if you wanted to.

Assuming it’s a 1:10 or 1:10.5 twist which was more common in factory loads I would stick with a 160 Accubond or Barnes TSX. From the powders you listed I would start with H4831 or RL26.

If Nilgai is on the menu, the 160gr Barnes TSX would be my first choice.

On the Barnes and the Bonded bullets re; Accubond, LR Accubond, Partition, etc

which have you 7mm Mag loaders found more accurate?

What’s your twist rate? Are you recoil sensitive? Muzzle brake?

Mine hated the ABLR. I’m shooting a 180 Berger at 3075 with a stout load of retumbo in Norma brass. It shot the eldm ok and the standard accubond well. Nilgai is about the only critter I wouldn’t shoot with my Berger’s lol. I’m running a 1/8 proof sendero light. 8 lbs 10 ounces with a leupold mk6. Without the muzzle brake It’s not real pleasant lol. Lots of muzzle jump. Running a WTO Brake and it’s not bad at all.

I can get my load info tomorrow or possibly later this evening. It’s near 80 grains of retumbo. I do not recommend that load without very carefully walking it up in your rifle.

I would use an accubond for nilgai.

I would start with these minimum..

I'd use the Partitions myself.

Which is more accurate??

Accubond
Accubond LR
Partition
Swift A Frame

[Killer]

My most accurate load for my 7mm is with 4831sc. Usually a softer bullet is more accurate but not always. I would start with the accubonds and go from there.

Not the norm but I landed on Sierra BT 175gr bullets with 60 gr of Imr 4350 for my weatherby 7 mag. It loves them.

Since '92, this is my 7mag "Match" load for my barrel:

60.1 gr 4831 (trickle feed for precise measurement)
162gr Hornady BTSP Interlock
Every brass is measured and trimmed
Every bullet is weighed. About 10% don't make it. Too light or heavy.

I've cycled a hundred loads with this caliber and barrel to rest with this combination.

Accubond LR

Totally depends on your gun and what reamer was used to cut the barrel.

I love the 162gr Interlock in my 7mm Sendero.. It shoots clover leafs with IMR4350.. Are you using IMR4831 or H4831??

I thought the reamer cut the chamber?
