I understand that. I usually back off a 1.5 grains from someone else's load. Cross check book specs on there load in a couple different spots and go from there

I will tell you what bullets I have used with success, but this is across a few rifles.
129g ABLR printed into .5" using RE25.
125g Partition was .75" using H1000.
140g Accubond ran .375" (3/8") using both RE25 and Retumbo.
142g ABLR ran under .5" with either Retumbo or H50BMG. H1000 was .75" with those.
150g ABLR has shown great groups hovering around .5", but I have only just started load development in my custom rifle with H50BMG so far.
I did use Speer bullets solely for hunting in the 90's and moved on when LR was in my sights. Used all weights in the HotCor line. Fantastic short range bullets.

Cheers.

I have a pre-64 M70 Westerner that I just put a takeoff pre-64 barrel on (so #2 has the same profile as the original and 1:9 twist). It was handed down to me by my father, so since the new barrel, I have been working up loads.
Old: my dads: both of these were @1.00MOA at best my dad always loaded at 3000FPS+
I have factory 90gr and 140gr WW-PP and have choreographed all at 3600FPS an 3200FPS, respectively (this ammo is NIB from the 70's)
120gr sierra Spitzer -IMR 4831
140gr Hornday SPBT-IMR 4831
Mine: old bbl
130gr Barnes TSXFB - H4831SC .5MOA until bbl gone
R&R BBL
130gr Barnes TTSX BT -IMR 4831/H4831SC -backed down charge and had terrible groups 1.5MOA
120gr Barnes TTSX -RL22 OCW running 55.6gr-61.7 (from Barnes data) shot 20 rounds inside 1", now I need to find that node.

At this point, I believe that you need to push this cartridge to 3000+FPS to get the accuracy I want. it shoots pretty flat out to 300 yards. and always has. I have taken many deer (Oregon/Washington Mulies) with it. Everything shot with Barnes was 200-400 yards and one shot. The older stuff is not always, but mainly two shots.

If you PM me, I can share actual data and targets.

I have 2 Win Pre '64 m70 264 Win Mags, one 26"bbl, one 22" Featherweight. I started hunting with the 26" bbl in 1975 using Sierra 140 gr SPBT on top of 60.0 of IMR-4831 (Sierra 3rd Ed). The powder is the older vintage, pre 1970, so the load worked but at the upper end of pressure. This load using Sierra tables est at 3200 fps. This load has taken many large West Texas muley's, antelope, and whitetials. All one shot DRT at any range. The 22" Featherweight was my Dad's favorite. He loaded a 129 Hornady using a IMR-4831 PO Ackley load, I'll not publish it but it was supposed to hit 3300 FPS. Again, one shot DRT with this load. Unfortunately throat erosion has retired this old hunter so it's on my rebuild project list. I have a Rem 700 BDL 264 WM 24" Stainless bbl that was a recent acquisition. I still need to work up a load for it and will probably go to 130 gr Accubonds.

WOW. My favorite cartridge 264WM.
I have been thinking of getting mine back out, haven't shot it in quite some time.
I'm wanting to try Berger's new
130gr. Hybrid OTM Tactical.
Trying to decide what powder between
H-1000, N-560 or 570.

Sneuses what gr bullet and what powders are you thinking of.

Winchester has not produced brass in a long time, so what are guys using?

I have a stash from the 90's of Winchester ww-super brass, it is by far the best brass, it makes my chamber dimensions perfect at .008" shoulder growth. I now have had to buy Remington 7RM brass and run them through my custom die to make them 264WM, but the shoulder grows .012". Can't get around that, but I'm happy forming brass testing primers and seating depths.
Remington brass is good once prepped, flash hole cutting, uniforming and trimming, haven't had any issues with it.
My other brass source is Norma, but it is 3 times the cost of Remington brass.
Wish Lapua made brass for it…

Cheers.

I still have 200 new in the red bags.
I've been using Norma that I picked up about 8 years ago 200, and one of our members had 2 boxes of new Nosler for sale last year for 110.00. I couldn't resist.
Last winter I got a AMP, so I opened the 4 bags of win and annealed them all.
And that's not including the few hundred rounds I have loaded.
So I'm looking pretty good .

Around 2019 I bought Remington 7mm RM that I sized close to saami CB to datum in a .264 die then got lucky and found some Winchester .264 WM almost a year later. I still need to build the rifle

I'm not much on sharing load info also, but will state with my pre64 sporter load was derived from Sierra #5. IMR4831 @61.3gr (.5 beyond their max load) with 140sbt (3.220" iirc) Been using that load for 40 years. Built a newer 264wm off a 110 action for 150smk's @ 3.500" using a McGowen 32" 7.5T. Should be supersonic past 2k yards.

I have 2 and both of the barrels the riflings I think where cut with a butter knife I had to fire Lapp both of them (I bought them 12years apart) the one has been re barreled with a 1 to 8 twist shooting 130 grain Hornady çx bullets behind IMR 3031. The other gun will get a new barrel soon

I am using Remington and Winchester, most twice loaded. If I wanted to buy new, Nosler is the easiest to find - for $$$$ (eeek!!). And I have a few boxes of original factory Win 140 gr still on the shelf if needed.

If anyone is looking for .264 wm brass I have a bunch.
Has been formed from 7rm brass.
Some twice fired. Most once.

I bought my first 264 in 1964. Still have it & others. Have taken a ton of deer & elk with it over the years. Still shoots great. It is a Rem 700 with the original 23 1/2" stainless Bbl. Yes I do have a good supply of 264 brass. I can supply a bunch of great loads from 100gr to 140gr.
