Winchester m70 pre64 264 Win mag load Development Speer grand slam EP3

[@brianstratton2522]

I’m using Ramshot Magnum, it seems to be the best in my rifle, those old screw machine Noslers are awesome, I still have a few from the 70s

[@ReloadingQuest]

Awesome. Thats good powder. I know I thought about that powder. Thanks for watching!

[@ReloadingWeatherby]

Just patiently waiting to hear what Weatherby cartridge you purchased.... No rush though.

[@jonbaniak9097]

I’ve been loading the 264 win mag for over 20 years now. The best powder I’ve used for it is H4831. Unfortunately, the reloading data for it is way underloaded for some reason? Compared to the same bullet weight in the 7 mag shows almost a difference in powder of 10 grains. I honestly think they are trying to kill this cartridge so you will buy one of the newer 6.5s? Good video!

[@ReloadingQuest]

Awesome I will have to try that powder out. I agree on killing it off. The 284-6.5 Norma does interest me the most on a 6.5 round. I love my 6mm and 30 cal guns though.

[@jonbaniak9097]

If I were building another gun on 6.5, it would be the 6.5-257 Weatherby mag. It give almost 26 Nosler velocity with less powder. I built a 28 Nosler and think this cartridge is the ultimate hunting round for North America. I nickname it the Grim Reaper. Also, you really need to give Hammer bullets a try. Best bullet I’ve ever used for a hunting bullet. Take care!

[@samuelfiorito2945]

Following just got this same rifle! Keep up the testing!

[@ReloadingQuest]

Awesome! Will do and thanks for watching!

[@RME1911]

Your bench looks like mine 😅 your color coding method is genius

[@martinfernandez5005]

Great video I've been looking for a load as well. I'm thinking of H1000 because it's temp sensitive and Speer Gold Dot 140gr. The bullet length 1.27" and has a BC advertised at .571. I've had it custom loaded before but I got no load work up from them but it stabilized great. If you have any more load information you can send my way 🙂

[@Lowballinoutdoorz]

I would definitely switch powder. And I've then noslers

[@ReloadingQuest]

Agree! Thanks for watching bud!

[@timothymcknight9485]

I just saw this video. What is the barrel twist rate in that rifle. I have a custom made 264 Win Magnum. I had my gunsmith team the throat farther out so I could extend the bullets farther. I found 59.2 grains of RL-22 with a Hornady 143 grain ELD-X bullets shoots half inch groups ( or smaller if I am good that day). My barrel has a 1:8 inch twist .

[@ReloadingQuest]

Thanks for watching. It’s a 1:9 twist

[@timothymcknight9485]

How has the load development been going for the 264 WM?

[@ReloadingQuest]

@@timothymcknight9485 I am going with the nosler partitions for now. Check out that video if you not seen it yet. I am waiting on getting my hands on some different bullets till I do more load work up.

[@rex8958]

What I use is Reloader 22 with a 140gr Hornady SST, average velocity is 3010fps. 5/8” group at 100 yards and she’s a beast.

[@ReloadingQuest]

That’s pretty dang good. Not sure this gun will do that with out free floating the barrel.

[@rex8958]

@@ReloadingQuest it’s possible just the journey there might burn out the barrel lol, honestly you might have to stick with a standard spitzer soft point flat base style bullet. It should be capable of hunting groups even with a non floated barrel

[@ReloadingQuest]

@@rex8958 if you watch my last video I did with the nosler bullets I finally got 1” group. And went with that load. It’s literally like a women. Temperamental ha

[@ReloadingQuest]

@@rex8958 what COL did u load to?

[@martinfernandez5005]

What's the grain weight used with Reloader 22 ?

[@unclejohn1053]

Getting it dialed in. Hey, it keeps you out of trouble!

[@ReloadingQuest]

100% haha

[@dyouden]

Reloader 22 works well in everything I put it in

[@ReloadingQuest]

Yeah that’s the powder I am leaning towards using. Thanks for watching

[@jamespugh]

Looks like ur getting it close Zak

[@blaynemacpherson8519]

I’m not the biggest fan of the 140 grain in the 264. I prefer the 130 grain tsx for bigger game and the 120 grain for deer. I did a bedding job on my 264 they made it shoot way more consistent. I’ve never had any luck with the reloader 22. Good video keep up the good work.

[@ReloadingQuest]

Yeah I am sure part of the grouping problem is it’s not beded and barrel is not free floated. But it’s not my gun so I had to work with how my buddy wanted to keep it. Thanks for watching! And the advice!

[@rex8958]

All I’ve loaded for 264 mag is 140gr SSTs and it’s grouped great. From what I’ve read and seen 120grs gives the peak performance from the 264 mag

[@ReloadingQuest]

@@rex8958 nice. May have to get my buddy to buy some and try them out. What powder did u use?

[@ReloadingQuest]

Thanks

[@ReloadingQuest]

I agree. ☝🏻 I am not a fan of 6.5 In general. Rather go to a 7mm or bigger.

[@ChrisFromThe740]

👍👍

[@yotereapers]

That primer box said $1.59for it.. man I wish prices where like that

[@ReloadingQuest]

Yeah you and me both

[@markdrewien5553]

Better then a Creedmore!

[@ReloadingQuest]

Agreed 100%

[@shannonfrericks1124]

Imr 4331 kicks more. Imr 4350 will turn on her charm.

[@gbett6835]

here's my secret 264wm 130gr AB sauce...use imr4350 around 57.5 grains, cci 200 lr primer and coal of 3.357 out of a 1:9 twist barrel

[@ericaustin7536]

I wouldn't waste any more time trade it for a bergara premium series they will stay under a 1/2 with your worst load

[@fredpierson7488]

Hornady 130 with 7828 works for me

[@ReloadingQuest]

Yeah just came to the conclusion that the barrel was no good. All shot out

[@fredpierson7488]

@@ReloadingQuest oh that's a bummer, they're a very accurate rifle

[@ReloadingQuest]

@@fredpierson7488 yeah it is but it can now just be a wall hanger and he’s looking to buy a new one 👍

[@ReloadingQuest]

@@fredpierson7488 not really collect pre64. But may if price is right

[@tacticalrabbit308]

Need to work on pointing camera where your explaining things

[@ReloadingQuest]

For some reason when I uploaded the video is cut the video frame down. The view should have been a lot wider.

[@ReloadingQuest]

Thanks for watching

[@ericaustin7536]

Buy a bergara

[@Manbunmen65]

That's a lot of extra work. You could just buy a 6.5 prc and shoot factory ammo at the same velocities you are reloading to. It's called the internet and gunbroker, buy cases of ammo...done.

[@ReloadingQuest]

If you actually watch the video you would know it’s not my rifle and I also do not shoot 6.5 my self. I won’t on a 6.5 caliber nor a 270. 7mm or 30 cal. But of course ur a troll and think ur being smart. Not only that, the fun part about Handloading is finding a round that it likes.

[@brownbouy3043]

Found the hype guy, good luck finding that ammo a few years from now

[@terrycalvert7812]

Grand slams always shoot the best between 50 and 90 tho off the lands and retumbo is to slow for 140 class bullets in a 264 you need to be using something like 7828 H1000 is as slow as you would want to use unless your goikg to be shooting 150 + weigh bullets!! Loads can be found with retumbo but there far and few between!! Anytime your using a traditional hunting bullet like the grand slams partitions interlocks or that type start at 50 tho out the lands and work further out when u find the charge with the best extream spread!!

[@ReloadingQuest]

What I found to be the problem with those rifle was the barrel was shot out. Had really bad heat cracking and was crazy how bad the rifling was ones I put my bore cam down.

[@charlesmullins3238]

I wanna love a .264mag but my 6.5prc will shoot 95s to 153s from 2900fps all the way to 3600fps with v max and A tips amongst every other weight and maker you can think of. 135 to 140gr is sweet spot with n560 I put 3 135gr a tips in 1 hole..retumbo…h1000..magpro..superformance..h4350 all used in prc with good results..🫡
