Home Forums Reloading Big Game Rifles Good 7mm Mag loads...

I've had great results with RL-25 and 160's. RL-33 is an interesting concept. I just so happen to have a can and will check this out.

It will be interesting to see if others get the same results as me.

I don't post here often, as it is a nightmare for me to get on this forum. Login issues and popups. It is the only one that is a problem.

Some of the LR .264 WM shooters like RL-33. From what I've read, it's made by the same Swiss powder maker that supplies RL-17. Reportedly, some of the technology that makes RL-17 a performer is used in RL-33.

I recently tested RL26 and the Barnes 145 LRX.

Rem standard primer
Nosler brass
70.0 grains for a mv of 3,220.

It shot consistent 3 shot groups of .5 or less.

Very pleased.....

Tikka T3
72.0 grains MagPro
WLRM
160 NAB
3.290"

First time at the range.

69 gr Retumbo

CCI 250
175 gr. PT, horn sp
2900 fps

Two rugers tang 'r.i.p' and hawkeye, plus a tikka T3 like this load. Older ruger averaged a little higher velocity, but not enough to worry about.

Seating depth depicts group size. Bug hole groups very common with just touching lands to .020 jump, gotta find the rifles happy spot

Have worked with both 140 and 150 sierra SPBT. Best results with 150. Used both H4831 and IMR7977. The 7977 load proved out to 1/2" @ 100yds. Details; Win Br, CCI 200, And 67 Gr. 7977. The barrel is an Apache prefit on a Savage 110. Awaiting an order of brass and will reconfirm and get chrony results. Your results may vary - So work your loads carefully in your rifle so as to prevent over pressure or accidents.

Here's a follow up to some loads I was working on (26 inch, 1 in 9 Rock Creek barrel). I'd like to reach 3100 fps with the 150 gr. Partition but I'm not there yet.

Bullet: Nosler 150 gr. Partition
Powder: IMR 7828 65.0 grs.
Primer: Federal 215
Case: Winchester
LOAL: 3.270 (2.744 Base to Ogive with Stoney Point)
Velocity: 3029.70 fps
ES: 38.75
SD: 14.59
Comments: Jam length 2.749 Base to Ogive with Stoney Point. Bullets seated for 0.005 bullet jump to lands

Bullet: Nosler 160 gr. Partition
Powder: Alliant Reloader 25 69.0 grs.
Primer: Federal 215
Case: Federal
LOAL: 3.285 (2.745 Base to Ogive with Stoney Point)
Velocity: 3030.59 fps
ES: 34.16

Anyone try vv165 ?
Seems close to rldr 22 ?
66.0 gr's of rldr 22 for me, 160gr accubond at 0.030 off.
It's consistent enough, that I can say, my gun shoots ragged hole groups.

And just the other day. 3 shots.

Nosler 140 grain accubond 65 grains IMR 4350. Kills em dead

Tag for future reference.

Lots of guys using reloader 22, I'm going to have to try it.

Nosler lists a max of 63 grains of Reloader 22 and the 160 Accubond. I ran that tonight in a factory SPS with a 26" tube and CCI-250s. I got a pathetic 2789 average. And this is with a Magneto Speed chrony with is spot on.

I realize the books are a "guide"....but 3 grains is a schitt ton over isn't it?

Not really. Carry on up until you see the velocity you're expecting, or until you see traditional pressure signs, whichever comes first.

Not surprising results from many factory barrels,and manual data.You may have completely different throating and barrel from what Nosler used to work up their data.

Seen it many times. Different barrels can have a substantial effect on velocities with the same loads.

Spot on, each bbl/chamber is an individual.

Bob's post nails it. 63 is pretty anemic in 7RM under 160NABs IME. 66ish is what shines in many 7RMs for me personally, some bbls can handle more w/o any hint of pressure and great pocket life. I've used it enough that 65 is what I would consider a starting load

Loader the mostly may as well be wildcats.
