264 win mag

I have a Winchester Mdl 70 .264 Win Mag that I am going to be using for this years elk hunt. I am going to use 140gr Accubonds and wanted to try RL25. I am having a hard time finding any info on using this powder for this gun. Accurate list a max of 60 grs and that is it. Has anyone else used this powder bullet combination? Does anybody have any insight or experience?

Thanks

Thomas

Re: 264 win mag

I have no doubt that the 140 Accubond will get the job done. I use the 130 Accubond in my 264 Win mag on deer. I live on the wrong side of the Mississippi so no elk experience. I have only recovered one 130 gr Accubond every other has exited even as close as 80 yards. The one that I recovered was from a large body buck shot at 111 yards that was almost facing me with just a slight left shoulder angle toward me. Bullet was placed on the edge of that shoulder and deer drop on its butt and fell over dead. On dressing it I discovered that the shoulder was smashed, lungs were wiped out and while cutting up the meat I found the bullet against the smashed ball socket of the right ham. Bullet was a text book mushroom that weighed 87 grs. If it will do all that to a deer I am sure that the 140 will hammer an elk. Bullet left the muzzle of my 27 3/4" Shilen barrel at average 3350 fps. I use 66.5 grs Retumbo, CCI 250 primers, WW case reformed from 7mm Rem mag cases, with the 130 AB at COAL 3.450, average 3350 fps and drives tacks.
I have never tried RL25 but have heard good things about it in the 264 Win mag. If you have a max of 60 grs listed then back off 10% and do a work up and see what you get. It all depends on YOUR RIFLE. My rifle has a tight chamber and I can not get to the max loads listed for Retumbo without too high pressure. A friend of mine uses 1 grain over max listed which is all he can get in the case in his rifle with no pressure signs because his rifle has a somewhat sloppy larger chamber. Good luck and good shooting.

That was my plan on how I was going to load it. I was just hoping others had tried it before me. I have used the 130 accubond with success as well. Recovered a bullet from a large mule deer shot broadside in the front shoulder at about 200 yards. Destroyed the first shoulder it hit, heart and lungs disappeared and broke the offside shoulder into pieces. I found the bullet under the hide on the farside. It weighed around 80 grains. The deer crumpled in its tracks.

Thanks for the encouragement.

Re: 264 win mag

Never could get that bullet to shoot for me. But I can't get a decent load with a 130 gr Accubond (tried IMR 4831, Retumbo) or 120 Sierra's( tried IMR 4831). I am at max load with all the powders and only getting 3033 FPS with the 120 gr bullets and the 130 gr were getting 2900 FPS. I am missing a few hundred FPS from somewhere. I don't know if I should be trying a slower powder or what. I am going crazy trying to get this gun to shoot consistent. I cant get it to shoot under 1.5" and the velocity is all over and low. Is this a sign of a worn out barrel?

Thanks

Thomas

Re: 264 win mag

I checked my load data site and max load of Rl-25 goes up to 65 gr, with various 140 gr. bullets.

I have worked up to 66 gr. of Rl-25 with 140 hornady and 140 Nosler partitions. Norma data shows 64.9 gr. of MRP2 which is said to be the same as Rl-25.

I have gone to slower powders for better results. I think Rl-33 would be a better choice but have not worked with it.

I used H1000 in my 264W behind 140 grain bullets, but never shot the accubond, with good accuracy and consistency. H1000 is an excellent powder if not compressed.

Re: 264 win mag

I appreciate all the responses. I am not sure what I am going to do with this gun. When I last had it out I could not find any consistent loads for the gun. The best load was only shooting at about 2850 FPS with the 130 gr bullet. I should be at 3100-3200 in this gun. It wasn't showing pressure signs, but was at the book max so when I made up my test loads that where I stopped. I am going to make some more up from the current best load and work up until I start seeing some pressure signs. I did notice that there was a lot of soot on the necks of the brass. It has me thinking that I am not building enough pressure to seal the chamber or I have chamber problems. This gun has me frustrated as I was supposed to use it on my Elk hunt on the 20th. I just can't get a group. I ended up ordering a 338-378 Weatherby mag for the hunt as I just cant trust this one.

thanks

Thomas
