Default Working on 7x57 loads

With this new to me 93 custom mouser 7x57 I have started working on a load I am using Hornady 139 Grn. SST boat Tail which I have never used before so hope they work out good. I am using Hogdon H 4895 powder which I really like and use it in most all my rifles I will only be using what the Books call for in a load.
I have used the H 4895 in my 7 mag using 120 Grn. Sierra soft point boat tail Reduced loads that Hogdon list on their sight and it has worked very well for me. When I had my Ruger Number 1 I used the Hornady 139 Grn pointed soft point boat tail and they worked good. I loaded up a doz. 7x57 today but will be next week before we get a break in the weather rain starting tonight through the weekend will report back as to the results Keep in mind I am old and shaky. I may go ahead and load a few of the Sierra 120 grain soft point and give them a try also while I am waiting for a good day to shoot.

Just curious - does your 93 have the original military barrel? Reason I ask is the military barrels were made to shoot a heavy bullet (about 175 grains).

Yours may work fine with the 139/140 grain bullets, but if by chance it doesn't it's just something to keep in mind.

It has the 2 step tapered barrel so I will keep that in mind if it don't like the light bullets

Barrel throat will be longer than a current commercial barrel set up for 120-140 gr bullets.

Glad someone is developing new loads for their rifles. It was getting kinda boring in this section.

Deacon, your M93 should be safe to shoot with US made factory loads and modest loading manual "book loads", but I would not recommend warmer 7 x 57 loads that would have been safe in the Ruger No. 1 you had. You are dealing with early 20th century metallurgy and while the Spaniards did rebarrel some M93s to 7.62, that was a CETME round which was loaded to lower pressures than standard NATO 7.62 ammo.

I have already shot it with some PPC loads 139 Grn. they work fine but about every other one would not fire primer strike looked ok but I have heard that some brands have harder primers. I reprimed a number of empty cases with Winchester brand primers and all of them went off I puller the trigger 2 or 3 times with the PPC rounds and they still did not shoot.
I never load any round no matter what cal. or brand of rifle to full power loads.
