Won't be long before I start doing some loading for this rifle. I know there probably aren't many people who load for this particular round but think 264 mag data.

What is your most efficient powder for a comparable round ? Bullet choices ( for hunting ) etc.

Thanks

264 win mag has a good bit more case capacity, almost 30% more than the 6.5 06.

Powders like H4831 or R22 would be a good pick.

Are you looking for heavier, 140 gr+ high BC bullets or lighter, 120-130 gr bullets for more velocity?

True 338. It's more than a little case capacity difference. I reckon I was just thinking overbore more than anything.

I have some 120 barnes triple shok's on order and some 140 hornady interloks coming as well.

I'm wanting to launch the 120's as fast as possible but the 140's don't have to be a scream machine.

I would try IMR 4350 with the 120 gr bullets.

I'd probably try IMR/H4350 in both bullet weights and H1000 in the 140s. Passed on a 6.5-06AI several years ago. Wish I'd a bought itt now.

What yall think about some R22 ? Burn rate is about right and I have plenty

R22 will probably get you top velocity with either weight bullet. Good powder except for lot to lot inconsistencies and very temperature sensitive is why I've been using less R22 in the last few years. Only using it in my 300 weatherby these days.

If you have a few pounds from different lots, I would try to mix it all together to avoid inconsistencies.

How far do you all like to set the bullet off the lands with Barnes ?

.050

I was patient. The answer is 4831.

Thanks bud. I've heard this elsewhere too

Thanks

There's plenty of data around it's not exactly a wildcat compared to alot

My uncle religiously used a 264 win mag for years. He loaded 125 gr partitions. Can’t remember what powder he used. He was old school about everything and swore by partitions.

I have used 125 Partitions ahead of 4350 for many years. Mild recoil, flat shooting , and deadly.

If he was old school he was likely using 4350 like Fred.

4350 gets the job done well in a lot of guns. You can even use it in a 375 H&H mag with 300 gr bullets for top velocity.

My .264 win mag load is a 140 grain Berger VLD Hunter. Don't remember the powder but AU338 might. I think it may be R22.

Retumbo. Maybe a few grains above the listed "book" max but I've used the same in my 264 and no pressure signs.

Great powder for the 264.

I don't have any Rotumbo but may pick some up

I think Retumbo will be a little too slow for the 6.5 06. Try R22 or H4350.

And if you find any Retumbo other than on Gunbroker for $100+/lb, let us know.

Goot grief... nm that

Shooters warehouse in Cullman has been keeping retumbo in stock

N165 with 140's gave me the best accuracy and velocity. Notes say I got about 3000 with 26" tube but max loads. I am sure y'all guessed I wasn't shooting pea shooter 120's this was my long range setup for years.

I'm hoping to roll some up this weekend and see what it will do. thanks for the input everyone

Interested in how it does.

Simmons in Bessemer hadRetumbo on Friday . Also H4350 IMR 4350 and 4831.

Rolled some up last night, didn't get to shoot today though. I'll post up once the results after I get the chance to shoot.

Loaded some 120 grain barnes ttsx's with IMR 4350 and some more with Reloader 22 then some 140 Hornady Interloks with With some reloader 22

Good luck with the new loads. What twist is that barrel?

1 IN 8

FINALLY got a day to try out some loads and break in this rifle. It did not disappoint. 4 different loads all under 1 inch with the 120 triple shocks and a max load of RL22 grouping under .25

Ohh wow.man that's awesome
That's always a good day.youll be ready for deer season for sure

What was the speed?

I did not chrony it but it should be in the mid to high 3200's

Yea sir! That’s what I’m talking about

I'm gonna chrony the next batch and I'll let yall know what its doimg
