7mm Rem Mag Reduced load

[Husker_Fan]

I want to work up some reduced loads for my 13 year old niece. Last year she took a whitetail doe with the Remington reduced recoil loads, which she shot well. Those are 140 grn corelokts.

She is going for a moose with her dad this November and I would like to know if there are any suitable loads for moose that won't be too stout. They will be in British Columbia not far from Glacier National park.

I have a copy of a Hogdon table from rcmodel, IIRC, that has lighter bullets with H4895.

Can I safely download with that powder or another one with a 150-160 grn bullet but still have a load that is suitable for moose?

For my own deer rounds this season, I am thinking about 140-150 grn bullets (perhaps accubonds) with H4831.

I think they call that load 7-08 or 7x57.

 

[rcmodel]

Lyman #49 lists several 150 - 160 7mm Rem Mag starting loads running barely over 30-30 velocity & pressure that should be pretty kind & gentle.

Speer #13 also lists all bullet weights using SR-4759 powder with velocitys around 2,000+/- FPS.

Unfortunately, John, they also call those rifles neither I, nor my brother own.

rc, thanks. I've been meaning to get a copy of they Lyman manual. The Hogdon manual I have doesn't have data for the application I am thinking of. I need to look into what minimum velocities/energies are for moose and go from there.

Husker,

Not sure about the weights you listed but you could probably get away using one of the Barnes TSX or TTSX in a 130 - 140gr weight instead. I would give Hodgdon a call on Monday and ask if they have any reduced loads for 140gr bullets. If so simply go from there. I wold say that H4895 might be a tad on the fast side for the heavier bullets. I have used it a LOT in other calibers like the '06, 308, and 243, for youth loads and most if not all were very accurate, and got the job done out to around 150yds. This however has been on whitetail and hogs, a moose might be something else entirely. However they all breath, and if you take that away they will stop. The question is how long and how far before they stop. With the Barnes your going to get penetration with out a doubt. Probably as much or more so than if you did use one of the heavier bullets.

Good luck, hope you find something suitable. However, this might also be a perfect excuse to add to the collection

i think 41 mag is on the right track here - run a light-for-caliber barnes bullet w/ h-4895 and you should be ok.

my daughter's 300 wsm does very well w/ 42-ish grains of h-4895 and 130 hornadys... this is a whitetail load, and she's never hunted moose, but if i were to attempt this for my daughter in a 7 rem mag, i would start w/ a barnes bullet and about 40 grains of h-4895 and work it up from there.

4895 loads down very nicely... the 300 wsm and 7 rem mag are close in case capacity, too. i suggest a mag primer w/ reduced loads.

good luck!

H-4895 is the slowest powder Hodgdon recommends for reduced loads in bottleneck rifle calibers.

You can get in trouble with traditionally slower 7mm Mag powders and reduced loads.
It called SEE, or Secondary Explosion Effect, Detonation, and a few other things.

Don't do it.

That is what I was thinking. I figured H-4895 would not be good with the heavier bullets, and H-4831 isn't very suitable to reduced loads, from what you folks have said.

My neice handles the Remington reduced recoil loads fine and those push a 140 grain bullet at 2700 fps. I'll check with they guide and see what he thinks.

Thanks.

Well, the concensus seems to be 160 grain bullets like accubonds or partitions. After a lot of reading I went with RL-22. People really seem to like it for the 7mm rem mag.

I'm going to test some loads at and just above the publishe minimum for this powder with 160grn Accubonds and see what works well. I'll likely go with the lightes loading that gives suitable accuracy. She won't be taking any 300+ yard shots, soe I am more concered with termial performance and recoil that with long range accuracy.

While I was at it, I loaded up some 140's to work up a deer round for me (again on the slow side).

Thanks for the help, and I'll let you guys know how they shoot.

 

[Husker_Fan]

Well, she got her moose an hour or so north of Glacier Nat'l Park in Canada this past tuesday night. It was a really good animal for that area.

I loaded 160 grain accubonds over 60.5 grains of RL-22. Her shot broke the near shoulder, passed through both lungs and stoped just under the hide on the far side. They recovered the bullet and I'll weigh it to see how it did on weight retention.

Congratulations to the young lady! And thanks for the update.
