    Don't know much about the Sierra bullet. I'm shooting a 130 grain Nosler Accubond out of mine. 58.0 grains of RL19. (Thats .5 grain under max.) My rifle will print them in just over 1/2 inch. (.550) Haven't chronographed it yet but should be a little over 3000 fps. Should be a great whitetail rig.

    The 140 Sierra will work well on deer but for elk I would go with either the 140 Nolser Partition or the 130 or 140 Accubond. I shoot the 130 Accubond with 66.5grs Hodgdon Retumbo out of WW cases with CCI 250 primers and average 3350 fps out of my 27 3/4" Shilen barrel and 1/2" MOA accuracy. I only WT deer hunt with it but if that bullet will hit the edge of the left shoulder of a big buck at 111 yards with it still going at least 3100 fps. Then smash that shoulder bone and travel length wise through it's entire body and be found in the right ham next to the ball socket and still weigh 87 grs and look like a text book example of expansion it will kill an elk. The problem with your rifle is the 24" barrel which hurts the 264 mag a lot. I would try some H-4831 or H-1000 with the 130 or 140 gr bullet. With your 24" barrel about the best velocity you can hope for is 3000 to 3100 fps which duplicates a 270 Win with the same bullet weight. But a lot of elk are killed every year with the 270 so don't feel under gunned. For the all around one load will do it all I would get some 130 Accubonds and work up my best load and GO HUNT either deer or elk.

    My family has a Model 70 .264 Mag that has been through 3 generations and is now back to me.:D We live in Colorado and have never found any game here that this caliber could not handle. Many mule deer and elk have found their way to the dinner table compliments of this rifle. Most were taken with store bought ammunition with 140 grain bullets.

    Congratulation on a fine caliber.

    I have used IMR 7828 with that bullet in a 24" barrel and get 3050 to 3100 fps.

    I've never shot the 140 but for deer up here in North Dakota, 100 gr partioners or 125 gr partioners do a great job. Running 63.5 gr. R-22 behind the 100 grainers, and 61.5 gr of IMR 4831 behind the 125 grainer. both shot realively well, under .5 MOA in their own guns. Not sure on the speed i have never chrono them, only book values.

    Never shot a 140 Sierra, but RL25 and 140 BT's or AB's run about 3180-3200 out of my 26" barreled 264WM. They are accurate as heck as well, from a sporter weight rifle. It took a bit of tuning, but it runs pretty well. I am using CCI250, Nosler Brass and RL25 for both loads.

    If elk are on the menu, I would look at the better built 140's, I think they would pay for themselves if you happen to connect with bigger bones..

    What would be a good starting charge of RL25 and the 140AB? I have a M70 with a custom Gaillard 26" barrel.

    I too have a passed down Rem 700 in a .264 Win Mag with a 12xx serial # that has killed almost everything in North America including 20+ moose. Since I have had it, I have reloaded using 63.5 gr of 7828 with the 140 sierra Gameking. This is a very accurate load out of this rifle and let me assure you that there is NOTHING in North America I wouldn't hunt using this combination. Is this the best calibre for some of our bigger northern game? No! but would I be comfortable using this gun on most game? Absolutely!


    I know...I know... Alaskan brown bear....grizzly...even polar bear... YES I would use this combo on ANYTHING!

    This may sound like a BS internet post but I assure you, I truely mean this! I have personally used this rifle for years and taken bears, moose, elk, deer and antelope with it.

    I am running 67.6 grains of RL25, CCI250's and Nosler cases. I would probably drop back 5% from there and begin load work. I kinda got lucky as the AB and BT all shoot the same, with the same charge. I tried Retumbo, RL22 and IMR7828. RL22 looked good for accuracy, but not so much on the speed side. 7828 and Retumbo were decent, just not as consistent as RL25.
