25-06 110 AB IMR4831 Book load

[bob_dobalina]

No offense to anyone, but doesn't the book max for the 25-06, 110 AB, with IMR4831 seem a bit light? 51 gr, they list 52 gr for the 115 NBT in the same manual, Hogdon lists 53 with a 117gr bullet, and Hornady 52.8gr with a 110 interbond. I know, different components and all, but what do you think?

As you know every rifle is different and you just have to work up safely to what works in your particular rifle watching for pressure signs as you go along. Your rifle might handle a bit more of IMR4831 and it might also start showing pressure signs before you even hit the 51.0 gr. mark.

If you have a chronograph they can really be a big help also when you are working up a load. Often times you tell if a load is too hot by watching what your fps is as you work up. Also helps to tell you how consistent a load is with the least amount of high to low deviation, etc. A Pro Chrony is only about $100.00 or a touch more and I think it's worth every penny to get one.

Yes I have a couple chronos and would definitely work up. It just struck me as light from comparative sources. Thanks sir

I use 53gns IMR4831 Case length 2.484" Headspace 2.046" Primer Fed LR 210 Gold Match Bullet Nosler 110gn AB
COAL 3.442" Comparator 2.870"
.25-06Rem Gives approx. 3120fps from my 22" barrel, shoots 1/4" MOA @ 100yds & takes red deer stags (Approx 300+lbs) in the rut perfectly out to 300yds if & when necessary.

Works in my rifle absolutely perfectly, but use your own work up procedure.

Another great propellant that I've tested in the last 12 months for this bullet/cartridge is Vihtavouri N560 51.2gns. slightly different bullet seating depth. Brilliant!

IMR4831 is no longer available in the UK due to EU REACH regulations in Europe.

Good luck

The reason for a lighter suggested max load with the AccuBond is because in my experience the toughness of the AccuBond jacket and bonded core is harder to compress than the Ballistic Tip and thus will cause more pressure with lighter powder loads. I have also experienced this with the Speer Gold Dot rifle bullets which are also a bonded bullet. All bullets are not constructed the same and thus you will have a different powder load to achieve a certain pressure.

ElmerThud you reports are what inspired me to try this load. I too have a 22" (22.5") barrel. I've done a bunch of work with RL26 with the AccuBond, but thought I'd give a more readily available powder a try. Now I'm not sure how available it is!

Just got back from the range and got 2936FPS out of 51gr.
Worked up to 52.4gr and 3000FPS no pressure signs. But that's as far as I went for now. No "flat spots" along the way either, kind of sporadic.

It definitely doesn't heat up the barrel as bad as RL26.

If you’re at 52.4gns IMR4831 without pressure signs, try going further bit by bit.
I don’t know if the cartridge dimensions I gave will work in your magazine, but if the COAL fits, try working up & see where it takes you.
I have around .050” to the lands.
If you can get Viht. N560 I have different COAL for my cartridge, but results are brilliant.

If you can find RL-25, it's magic in my 25-05 rifles with both the 110 AB and the 115 BT.
3150 fps across the screens can be achieved from a 24" barrel and has punched 1" 5 shot groups at 200 yards on multiple trips to the range.

Try some Retumbo at 57-58g if you have any...It will really wake up the 25/06 and get you 3200fps. I used it in my last 25/06 with 100g at 3400fps and 115g NBTs at 3200. Fast and accurate! Excellent coyote and deer loads...

I have... and I don't. All I used to burn in my previous 25-06 was Retumbo and 120 Partitons. I did a lot of work with RL26 with my present 25-06,and never really settled on anything I was happy with mostly because of being overly cautious being that I only have QL data to work with. Then one day I loaded up 5 rounds with the last of my Retumbo max book load for the 110AB and it shot awesome - very accurate and fast. And that's the last time I've ever seen Retumbo. I hope I'm wrong but I don't think we'll ever see it again, but if we do I'll buy an 8 lb jug and be done with it.

I haven't used RL25 but as mentioned have worked with RL26, but stopped well short of QL max. What held me up was Alliant's data being much lower, and seeing other member reports of higher velocities with much lower powder charges. I emailed back and forth with Alliant and they mentioned the 25-06 being a 62K PSI gun, so maybe that explains their numbers- they are building loads for older guns? Anyways I may take another run at RL26 and I hope the new Nosler manual has some load data to guide me.

This whole IMR4831 kick was strictly to try out ElmerThud's load and haven't done anything more with it since I started this thread.
