[Dorian Gray]

I'm just getting my feet wet with reloading, so I dont know much. But what's the powder used in the first load?

 

[chuck nelson]

I’m shooting the 145/150’s in my 7MM Mashburn at 3200 fps (very 7RM ish). +/- 3” is about 310 yds and it carries 1500 ft pounds to 600 yds plus. And it shoots like a house a fire. As a friend says, good bones that 7mm Rem Mag.

 

[todbartell]

what's the powder used in the first load?

It's Barnes factory ammo



Watch out Chuck, those Barnes are no good for hunting I hear

 

[chuck nelson]

I bet I lose all sorts of game.

 

[john-brennan]

I have to get some of that R26 bet it works in my 270WSM, I used Retumbo in my Win M70 7mm RM with 160gr accubonds and with Max load I was getting 3055 to 3075 fps and it was accurate, should have kept that rifle.

 

[Gatehouse]

I use a 3006 with 180 grain bullets its the same thing

 

[stubblejumper]

I like the 150gr TTSX, but at 3400fps out of my 7mmstw.

 

[Dorian Gray]

It's Barnes factory ammo

Oh, didn't see that the first time I read it .

 

[Pat Brennan]

Very little game you cannot take effectively with a good 7 mag and one of the heavier premium bullets.

 

[chuck nelson]

The 175gr Partition is a giant killer.

 

[Hitzy]

Factory 7mm is notoriously light loaded.
How well do the solid coppers expand at long range and low velocity?

 

[chuck nelson]

How far are you shooting?

Barnes says 1800 FPS and I have found no reason not to agree with that.

 

[dan belisle]

I usually run the 160 gr partition over RL22 in all the 7 RM's I own and load for. Very good combination. - dan

 

[Leeper]

When the 7mm Rem Mag was first introduced, 175's were advertised at 3070 fps and actual velocity was often within 50 fps of that. Those rounds were loaded hot! Todays 175 grain loads will match a stoutly loaded 30/06 with 180's. I garantee, had Remington advertised 175's at 2700 fps, they probably would have never sold a 7 Mag. Of course, the funny thing is, the new, limp-wristed, loads still kill game just fine.

 

[WhelanLad]

I thought that Vortex stuff was suppose to be fairly hot , that doesn't show it's very hot

 

[Eagleye]

I have loaded for quite a number of 7mm Rem Mags over the years. Found a few interesting things:
Chambering varies considerably, depending on manufacturer and vintage. Throats vary a lot also.

However, I have always been able to flirt with 3100 fps with the 160/162 grain bullets. Powders of
choice include H4831, Norma MRP, IMR 7828, Reloder 25 & 26, Reloder 22, Vihtavuori N165. Most
7 Rem Mags come with 24" barrels, but 26" tubes are out there, and will usually yield a bit more
velocity. Loaded with proper bullets, it is a very effective chambering, and shoots 160's about as
flat as a 270 does 130's, arriving at 400+ with plenty of energy to take moose or elk.

My present 7mm Rem Mag, an older 700 BDL, does 3070 with 66.5 grains of MRP, and shoots .7 moa.
What is not to like? Dave.

 

[The Outsider]

Last year I worked up two very accurate loads for a late 1970's 700 BDL in 7MM Rem Mag,
using 160 grain Partitions as well as 160 Grain Sierra GameKing hollow points.

The charge for both was 65.0 grains of RL22, with velocities around 3000 FPS, shot a nice Muley buck with one of the Partitions last fall,
it dropped in its tracks.

Last week I fired a box of factory 175 grain Core Lokts through another 7MM, and velocity averaged about 2800 fps.

 

[boxhitch]

The J&H shows up in energy, where the extra 300 fps takes the 1500 fp
extras 30 yds mpbr....mmeehhh

 

[AP]

a careful reloader with the right powder can get 'very' close to 3000fps with a 270W and a 160 nosler partition
