Home Forums Reloading Big Game Rifles 25-06 top end with 100 grains

It would seem that reloader 25 would be the best powder then? How would norma mrp compare? Has anyone ever quickloaded this data?

thanks!

I get just under 3,400fps with 100gr Nosler BT and IMR 4831. 24" tube. If the Chrony read 3,300fps I don't think I'd be bothered.

I guess I like my face arranged just the way it is. When my chrono reads 3300 for my 25-06, I quit adding powder. IMHO 3400 is way over 60K psi in a standard 25-06 chamber.

Suggest doing linear extrapolation of known pressure-velocity data to see what neighborhood 3400 is in. And powder doesn't burn linearly at the top end............

Using hodgdon website data and H4350, the velocity, grains powder, pressure info at the top and bottom are: 47.0 gr, 3038 ft/sec, 47.8K CUPC, 50.0, 3155, 51.5K CUP

Equates to 39 ft/sec/grain of powder, 1.23K CUP per grain of powder.

To reach 3400 ft/sec, you need to burn 6.3 grains more powder. Burning 6 grains more powder raises pressure by 7.7KCUP. Total pressure = 51.5K CUP + 7.7K CUP = 59.2K CUP. without converting, I'm guessing that to be 70K psi.

In my experience, I get more velocity at a given powder charge than hodgdon states on their website. I'm guessing I have more pressure to go with it. 50 grains of H4350 in 25-06 gives me 3275 ft/sec with a 100 TSX. 3300 works fine.

My Nosler #3 book lists 54 grains IMR4831 with 100 grain bullets at 3490 fps.

I get 3500 fps out of my 26 inch Sendero.

The 257 Weatherby will beat that by 70 to 80 fps. Not much difference IMO.

If I remember correctly MRP models a little faster. Not sure how it will really perform. Do you have some, or know where to get it? I would really like to try some in a few different loads but can never find any.

3400 should be obtainable within 60K from 24"'s with the right powder and a good (fast) barrel. As always, watch your pressure signs. Yours may go faster, or say "Whoa" before you get there.

3500 with RL22 and 26" tube. Devastating on deer!!

I found mrp for sale online....I just googled it...

anyway 3500 does sound amazing on deer. I shot a deer with .257 weatherby with a hundred grain hornady at what was supposed to be 3550. The bullet went in at 200 yards broke both shoulders and was under the hide on the far side. I really didn't want to have a 26 inch barrel when I bought the 25-06.

I break 3500fps with 100gn TTSX's in my 26 inch tube using W 760. No other powder comes close.

I suspect you could get 3500 FPS with a 100 gr. bullet but I wouldn't..That kind of velocity eats up barrel steel pronto..I would go with 3200 FPS and bet nobody could tell the difference..

I bet it is devastating on a deer, I also bet you get way more blood shot meat than I care to deal with..A 100 gr. bullet at 2800 FPS is my idea or a deer load in the 25-06..It kills well and isn't too bad on blood shooting the meat..

Those that drop that old frivolous gem of wisdom that if you shoot them in the ribs all is well..Not so in many cases, you still can get a lot of the prime backstrap and you can ruin a shoulder without even hitting the shoulder as the damage can run under the shoulder in the ribs and on the inside of the shoulder you get a bubbly mess..I would prefer the neck shot with a hi vel round like were discussing. Better yet this kind of velocity is best stuck into coyotes, etc. or perhaps used at very long range.

I have found the 25-06 to be an outstanding Mule Deer rifle with 117 to 120 gr. bullets at say 2800-2900 FPS.

Being a 25-06 fan and user, I've never[so far] shot any 100gr bullets thru it. But at those velocities that are being mentioned, what about eating or burning barrels? Just asking, as I usally shoot 115-120gr bullets @ 2900-2950 FPS. Thanks guys. Tom

It isn't the velocity that burns out barrels - after all the maximum velocity is at the muzzle, not in the throat where all barrels wash out. It is the high pressure (and thus temperature) that is needed to get those high velocities that damages steel. You can burn out a .25-06 with a 3000 fps load faster than with a 3300 fps load if you tried.

Factory Ruger M77 with 24 inch barrel, I was able to get 3400fps with Varget, IMR4350, H414 and the 100g TSX.

Yeah, I think it is possible.

The 53g load of IMR4350 that Jordan shoots is my accuracy load as well at 3444 in my rifle.

In a couple 24" 25-06's I could get 3400 with 57 grains of RL22 and a mag primer in WW brass, but I felt like I was stepping on the gas pedal pretty hard. I backed off to 3300 fps and couldn't tell the difference on animals or long range targets.

My load as well, less the mag primer. It is a published max load and in my rifle, there are no obvious signs of "pedal to the metal".

3,415 fps with the 100gr. TTSX.

I love tossing in my beloved 260 Remington..

short action cartridge... 43.5 grains of IMR 4064... 3350 fps out of a 22 inch barrel and 3450 fps out of a 26 inch barrel...

so how much more powder do you have to burn in a 25/06 to match that??? hahahahahahahaha...

plus can your 25/06 shoot 140 grain bullets at 2750 fps?

Can your 260 shoot a 75g bullet at 3700-3800 fps?

To answer your question, yes, if someone made a 140g bullet.

My 3,415 fps is out of a 22 1/2in. barrel............

That is pretty impressive velocity from a 260 rem. The only thing is that the ballistic coefficient is better for a 25 caliber 100 grain than it is for a 26 caliber 100 grain. I find this unusual because 25 rarely has a better coefficient than anything. This is one of the reasons why I want all the velocity that I can accurately get. gS custom makes a 100 grain 25 with a .45 ballistic coefficient which when thrown at 3450 would be a good enough ballistic coefficient to make the 25-06 down right evil. Which is why companies in the us don't make good ballistic coefficients in 25 caliber. It would make it hard to sell new fancy guns.

Maybe a 260 ai would be cool because I don't think that a standard 260 has the powder capacity to throw really long heavy bullets as fast as I would like. Don't get me wrong 2750-2800 is cool but I like faster. Back to 25-06.

so why would you pick a shot action cartridge to save 1/4" and then add 4 inches to the barrel try to make it into a 6.5/06?

And using 8 or 10grain less powder per shot saves you maybe 3 or 4 cents?

The 260 is a great little cartridge, probably close to perfect for deer, IMO. Don't see the need to try to make it something that it is not.

and the reply is yes, if someone made a 75 grain 6.5 mm bullet...LoL...

actually 85 grain Sierra HPs can be run at a hair over 3500 out of the longer barrel...

also remember, that 260 is running about 15 to 20% less powder to accomplish that...compared to the 25/06...

I do think the 25/06 is a saner choice than a 257 Weatherby.. but in the 25 caliber world, I am a lot more impressed with the efficiency of the 250 Savage AI and the 257 Roberts, and Roberts AI, over the 25/06....

I shoot two calibers on each side of the 25/06, the 6mm Rem on a long action, and the 260 ( and 6.5 x 55, 6.5 x 57) on the other side...even tho I picked up a 25/06 heavy barrel for my Savage Actions, I am debating where to turn it down to a 250AI or a 257 Roberts instead...
