    7x64 loads

    Just building a custom 7x64 on a sako trg,s action looking for any reloading recipes looking to use 120/140 grn bullet area

    I asked a similar question. 7x64 load data I haven't actually started loading yet. Data is quite hard to come by though been told you can use starting loads for 280 Rem and work up. I'll watch this with interest.

    Gun is in the process of going to proof house just found 140 seller & bellot cases at old stock prices got the dies off here a few months ago vit 550 looks about best on the internet so far

    There is not a lot of data out there. Norma would be good 7x64 - Norma
    but it is not available in the UK . H4350 seems to be the most popular but hardly any around at the moment.

    I have just looked at the Nosler reloading manual, the 280 Rem data in particular. This is very close to the 7x64. I use a 6.5x64 which translates to a 6.5-06. The data for the 7x64 for the 140 grain partition suggest Varget, (41-45gr.), VN160, (50-54gr.), and Rel 19, (53-57gr.) for starters. I have been delighted with my 6.5x64 and, with a Krieger barrel, have found it to be very accurate. I suspect that your 7x64 will be just the same. Sounds like a cracker.

    Here is a reply I got from ramshot powders. Excellent customer service, Here is the load data that you have requested.
    Caliber: 7mmx64 Brenneke.
    Barrel length: 24”
    Powder: Ramshot –- HUNTER.
    Bullet weight: 140 grains Barnes TSX. COL: 3.300"
    Start load: 52.2 grains (2625– 2725 ft/p/sec)
    Maxi mum load: 59.8 grains (3050 – 3150 Ft/p/sec).
    It’ important to note that SAFETY is our prime concern therefore we strongly recommend.
    TO ALWAYS BEGIN LOADING AT THE RECOMMENDED

    I have 3 of them, so I am in the process of working up good loads, or trying good ones others have found. Can you get 154-gr, 150-gr, 160-gr bullets?

    I have one older full-stocked Mauser carbine.
    I just finished building a wood stocked 600mm barrel rifle, mounted a scope, working up loads while maybe add iron sights to it.
    A Steyr Pro Hunter with iron sights is on the way here.

    Like the .270, it likes slower powders like RL-19, N-160, RL-22, H-4350.
    What powders and bullets do you have available?

    For 140-gr here are the max loads ( which are probably the more accurate ones, too).
    IMR-4831 54.0 gr may be max, so start at 50.0 gr.

    58.5 gr Reloader 19, Vel 3020 from 600mm barrel. about 58,000 psi

    61.0 gr Reloader 22, Vel 3055 fps, 57,433 psi

    This illustrates the risks of asking for reloading recipes on a forum. This post gives data for a .280 Remington with a 26" barrel - check it out ...........

    Southern's Hornady data is for a 7x65R and dates from 1985. Both these cartridges are similar to the 7x64, but I think that's a different animal if you're making your own.

    Very interesting proposition though, but i'm not sure that I could wait 10 months to reload for it like shbangsteve, as it would have to be up & running within 24 hours.

    There's quite a bit of solid source info on the cartridge, but very little in the U.S. As a start, try to get hold of the book I quoted on steve's original post.

    It will end some illusions. KW uses 2 different rifles (24" and 26" barrels) in 7x64. There's a separate article on the .280 which shows that it's a good bit faster (again in 2 rifles). This is no surprise & could be predicted from a larger cartridge. The verdict is that the 7x64 is not an ultra-high velocity job, and will struggle to reach 2900 with a 140-grain ...not that this matters very much as it's got more than enough to do the job it's intended for.
    If I'm going to be accused of it then it's just as well I did it.

    All the Hornady data runs to the mild side.
    When I get home from business travel, I will post the 7x64 loads from more new manuals.

    I have been gathering and trying loads from other 7x64 owners, and most of my loading has been for my old Mauser carbine.

    Now that I have the new barrel on my full sized rifle, i will run what I have through it.
    But I won't work up any new loads until I can work on them through it and the Steyr together.

    The reason I asked about powder, primers, and bullets available is that, of the proven loads i have, there is no use sharing them if he cannot load them. But I don't mind, and already have posted some for 160-gr Sierra. Hornady stopped making almost all sporting bullets for about nine months, so that is another problem with their recipes.
