I thought that I'd open a can of worms and throw this one out there.....
I just placed my order for my Cooper M52 LRX in 264 Win Mag. What's the consensus of the ideal bullet if I want to use this as a deer/elk rig out to 650 yards? It will have a 26" 1 in 8 twist.
I've got most of the 6.5 bullets out there so let me know what you think...
Thanks in advance for the help.

I don't know how it would do at 650 yards but at closer ranges I really liked what the 130 gr Swift Scirocco did at 264 WM speeds. I would probably be looking at the 130 or 140 gr Accubond's for what you have in mind. Might be a bit destructive at closer ranges but would survive the impact.

I had a Cooper 56. It shot 140 Accubonds well. I didn’t like the cheap made safety or the loose magazine. Traded it for a pre 64 model 70.

I'm using the 142 gr ABLR in mine. But I think any of the AB's in the 130-142 range would work well. I chose this one as some of the game I take isn't the largest deer on the planet. I wanted something that was tougher at the higher velocities inside of 200 yards or so but still held together well enough to punch through an elk at 500 or so.

I haven't tried any of the heavier bullets that are out there but most, if not all, are flat-based, round-nosed bullets. For the ranges over 400/500 yards I'd think you'd want something with a better bc than those heavy one's have. Matrix makes a 150 grain VLD style target bullet but I'd be hesitant to shoot those at any distance where velocity is above about 2800 fps. Same with pretty much any of the 'match' bullets.
Berger's heaviest .264 caliber is 'only' a 140.

I think with any of the Accubonds or similarly bonded bullets in the 140 grain range you should be good to go on any deer-to-elk sized game out to your 650.

DennisinAZ posted about just taking a good sized elk in AZ with his 6.5/284
and a 143 grain ELD-X....I'd try that if you are into trying new stuff...

If out and just want to use old tried and proven... 140 grain Partition...

If you want a reasonable chance at getting an exit wound, then a 140 accubond or 127 LRX fills the bill. In my experience, the 143 eld-x is a bit fragile for elk at 264 speeds. When both deer and elk are on the menu, I’m loaded with accubonds. For deer when I’m anticipating a long shot, then I’m packing the 143 eld-x. That said, I did take a decent size cow with the eld-x last fall.

It will be interesting to see how the 155 Berger will do, some have been testing, will be available next year.

The 155 Berger may be good, tried 140’s, didn’t like them. The extra weight may help them stay together.

Bergers or Accubonds.

I would like to see what loads and velocities people are using for the 127 LRX loads. Especially with RL 22....

I use 70.6 grains of Ramshot Magnum and a Barnes 127 gr LRX.

Thank you!

What kind of velocities and groups are you getting?

double thank you!

I will have to look up my notes. I will post later.
