25-06 reload data

Ok, I am preparing to begin load development for my Savage 25-06 (26" barrel). I have never reloaded before.

I will be using Norma brass with 110gr accubonds. I have decided to start with H4831 for powder.

Nosler's website lists 47 grains as a start point, with 52 as a max (and most accurate) for the 110AB
Hogdgon lists 51 grains as a start and 54.3 as max for 100gr partition
Hogdgon lists 48 grains as a start and 52 as a max for 117gr hornady SPBT

I also found an old post on another site that shows Quickload calculating a max load of 57.2 grains behind the 110AB (developing 63,000 PSI in a 24" barrel)



Obviously it is dangerous and foolish to start at a max load. Most sources I have seen suggest starting at 10% under max and working up, but that puts the Quickload starting point near/over the max suggested by Nosler and Hogdgon...

This is where I ask for advise from those more experianced than myself...

What gives? What is the REAL max load for this cartridge/bullet/powder?

Thanks in advance.

I use H4831SC which is the same thing as H4831 but smaller granules of powder for easier metering. I use 54gr of H4831SC for my load with Norma Brass and 115 gr Berger VLD bullets.

I would start at around 52 gr of H4831 and work your way up. You can do so in .5 gr increments and see what gives you the best results and then work from there.

Re: 25-06 reload data

Ok, I went and looked through Hogdgon's info again... It seems their data is VERY conservative...


With the 100 grain Partition their starting load of 51 grains is listed at 46,800 CUP, the max of 54.3 is listed at 51,400 CUP

With the SPBT their starting load of 48 grains is listed at 43,000 CUP and their max of 52 is listed at 50,900 CUP.

SAMMI spec is 63,000psi (approximately 53,000 CUP)


It looks as if Quickload's max would be correct... Or am I off in left field somewhere?

Re: 25-06 reload data

Always remember that when you are reading numbers out on a site that the poster may have typed an incorrect number. It's best to back off the max charge in a manual just like you mentioned when starting out and watch for telltale signs as you go up the ladder towards what they show as max. It may or may not be that in your particular rifle. I load 50 grains of IMR 4350 behind my Hornady 117 grain BTSPs for my Ruger 25-06 and they are less than 1/2 MOA and are deadly. I could have gone much higher, but stopped with that accuracy and they're still running right at 3000fps. I also use their 100 grainer in my .243 with IMR 4064 and 150 grainers with IMR 4350 in my 30-06s with similar results.

Re: 25-06 reload data

If you don't have paper load manuals or one of the CD's like Sierra's interactive load manual, then Hodgdon's online manual is a good place to start. Not all of the bullets are listed and neither are all the powders. However, the starting loads are conservative, and the max speeds are pretty achievable in a standard length barrel (24"). Nosler also has an abridged "loading manual" online. Start at their low suggestions and let your rifle tell you where it is and isn't right.

I realize that you already have looked at these to gather information; but as I look at the numbers they all make sense except for " I also found an old post on another site... Quickload calculating a max load of 57.2 grains behind the 110AB (developing 63,000 PSI in a 24" barrel)" I don't trust that load at all because it wasn't published by a reputable source. You only get one set of eyes, one nose, one face, and one life; don't mess it up because somebody said it was fine on their quickload. Going above max load listed in a book is usually ill advised by the load manuals, but if your chronograph and brass/primers are saying you havn't made it to high enough pressures (as compared to load manuals) then you can keep going 'til you achieve that.
Good luck.

Re: 25-06 reload data

I have been shooting the 25-06 a long time. Best deer killing round I have ever fired. I have learned that it likes to be pushed almost to the max to do its thing. One of the 4350s or 4831s will usually get you what you want. Two of the best loads that I have ever found that I use for deer is with Sierra Pro Hunter 117 gr bullets. Either 52 grs H-4831, CCI BR2 primer and Rem case, or 49 grs IMR 4350 with a CCI 250 primer and Rem case usually shoots really well in most rifles. I am hearing good things about Retumbo and the 110 Accubond. With H-4831 and the 110 I would start about 52 grs and work up in .5 grs at a time and do the same with from 49 grs with IMR 4350 until you find accuracy without too much pressure. I have not shoot any of the 110 ABs but I have shot just about everything else from 100 to 120 gr in actually killing deer over the past 30 years, 20 of which I did crop damage control, and my pick of bullets is still the plain Jane flat base 117 Sierra Pro Hunter. Super accurate and it just drops deer in their tracks and they don't break your bank to get them. Just some of my findings. Hope they help you.
