7x57 loads

[hornsurgeon]

just got a sporterized fn venezuelan mauser in 7x57 for an absolute steal. i already have 140 gr sierra pro hunters for my 7mm-08, and h4831sc, h4350, varget, and reloader 22 powders. primer would be a winchester large rifle as i have about 7500 of them. does anyone here have experience with this round and have any suggestions for loads? if the sierra won't work i think i would be trying the AccuBond next.

I have an FN Commercial Mauser from 1953 in 7X57mm and love it! Here are the loads that I have worked up to date. The best one uses the 139 grain Hornady Interlock Flat Base, it routinely shoots 3 shot groups at 100 yards, around 1/2". Hope this helps, and good luck!
-TB

IMR 4350 - 46.0 grains 2,700 FPS - 139 grain Hornady Interlock FB (.5" avg.)
RL 19 - 47.6 grains 2,700 FPS - 140 grain Sierra Gameking (1" avg.)
IMR 4350 - 47.5 grains - 140 grain Nosler Partition (1" avg.)

I have a 98K that I use 140 Serra pro hunter in whit 48gr IMR 4350 I think the COL was at 3.0" but I'd have to check, oh yeah I used R-P brass, and it shoots real well do not know the velocity.

But the important part is that you got an answer for your question. I'm getting ready to do allot of playing with mine as soon as I get a new bolt handle and drill and tap the receiver and toss on a scope so I should have some good info for you in January or February if we get a break in weather. Got to love the Oregon winters!

I shoot
50gr H4350 with a 139 Hornady flat base
49gr H4350 with a Nosler 140 BT
46gr H4350 with a Nosler 150 BT or Hornady 154 flat base
Remington case
WLR primer
all shoot under an inch for 5 shots/100yards
The 130 BTSP Speer does ok
I have tried 120 grain bullets but have not done well with them

Have an old Mauser rifle,7x57 which I haven't loaded in quite some time. I used to load 44 grains of IMR 4064 powder with Speer 130 gr. spitzer bullet. This makes a nice deer round. Lately I've been loading for 7mm Mag. The 7x57 is fun to shoot.
