I've got a Remington Model 7 in 300 SAUM with a 20" barrel. My 12 year old daughter can handle the size of the gun itself, but the recoil is too much for her. She shoots my 308 long range with no issues. I would like to have her get use to the 300 SAUM (fit, shouldering, sight, etc) over the next couple years because I promised her an elk hunt after she turns 14, and that is the gun I would like for her to use.

Question is...

I would like to load up some 125 grain bullets but at about a 308 powder charge. I am wondering if loading down this much in a larger volume casing would present any hazards?

I load down sometimes but use a cast lead gas checked 170gr bullet.
I think the volume of the 300 SAUM case is close to a 30-06 AI.



Hodgdon sight states in their reduced loads that if a bullet and H4895 powder is used in their data then you can reduce that load .
Multiply the max load by .6 to get the reduced starting load..
read here.

It does list 125gr bullet and the math comes out to with 125gr nosler BT
62gr is max and multiply by .6 =37.2gr start..

Thank you! That helps a lot.

Next part of this question...

I would assume that with a reduced charge, it would be better to use a large rifle primer rather than the magnum primers I usually use in that SAUM?

If you have both then try both and see what it likes.
I use cci 200 in my 30-06 with 11.5gr of red dot for 1400fps with the lee 170gr gas checked bullet.
I would think 13gr of red dot and regular primers and that bullet would be a neat load.

I have also used 150, and 165 grain jacketed bullets with that 11.5 gr load in the 30-06.. less velocity than the lead by about 100fps.

Kicks less than a .223 bolt action.

Being a shorter case, you'll not run into the "powder in the front" issues that would on a longer case, if that's what you're worried about...........unless it's extremely reduced. I've loaded tons of extremely reduced 45/70 loads, somewhat notorious for power up front issues, and we'd used case filler over the powder to take up the extra space. I don't see this being an issue in the .300 RSUM imo.

There's your load^^^^^ for light recoil to teach the youngen!!! or you could try 16gr of 2400

It might be a good idea to stay away from reduced loads of rifle powder until you learn more about it.
Just stay with pistol/shotgun powders there are many you can use in the 13-20 grain range and you
won't have to worry about where the powder is positioned in the case.

Just to name a few, there are more.

Look into some TrailBoss or 5744 loads.

Before you try any of these loads, I would read the reduced loads in the Lee Reloading manual 1st edition.

It is explained very well and gives a simple 8th grade arithmatic problem to use bad be safe.

and as a last resort - the .308 will do a fine job on elk -

I wouldn't consider using a pistol powder at all. Just me. Here's what the latest nosler manual Shows in 125gn bullets in a 300saum. Another option would be to put a break on the rifle. They can be extremely effective in reducing recoil.

Here's the data Barnes shows as well.
