Just a few comments:

The latest versions of IMR4350 and H4350 are very close in burn rate. This is probably because Hodgdon owns both lines now, and doesn't want people getting into trouble with data that varies between the two 4350's. In my own rifles they act very similarly, with the same powder charge resulting in similar velocity and accuracy.

The 156 Oryx is probably my favorite 7x57 bullet in the 160-grain range. It is VERY accurate in my rifle, and while it penetrates pretty deeply, it tends to kill quicker than either the 160 Nosler Partition or 160 TSX, probably because it opens up wider than either of those.

In general, though, I have come to the conclusion that for deer-sized game, bullets in the 140-grain range kill more quickly than heavier bullets, due to the extra velocity. Favorites are are 140 Partition and Ballistic Tip, and the 139 Hornady, either flat-base or boattail.

I had a Juenke machine for a while and finally gave it up, because I was spending too much time spinning bulelts for relatively little gain. There's some correlation between the Juenke machine and accuracy, but evenually I decided not enough to worry over in hunting bullets. If I want extreme accuracy for longer-range shooting I just use Sierras, Ballistic Tips or Bergers.

Though not yet hunted I did bring two back last year after finishing my time living in Canada, a BRNO and a Walther (the left one, the right one is an 8x57). Been looking for the "right" one for years. Maybe one gets out this year.

A few years ago, I found the IMR 4350 was a bit hotter than the Hogdon, IMR loads in my Ruger, gave faster than Hogden, not any where top of spectrum loads so no pressure signs on either load.

When AR 2209 (H 4350) was released it was a little faster than IMR 4350. After Hodgdon started using it as a replacement, it was tweaked a little slower than IMR 4350. No need to advertise this sort of ajustment as it won't cause handloading issues (because the pressure is lowered) and the serious reloaders always test new batches of powder and alter the loads to suit.

Thanks again John for the reply here (and over in the reloading forum). The 156 gr Oryx has been of interest for a while--although I'm sure the 160 partitions would've sufficed for my intentions. I guess that's part of the adventure...learning about and field testing a 'new' (to me) hunting caliber.

If it was just for deer-sized game I probably would've stuck with the faster 140 grain bullets but I'm going to RSA and will have opportunity for some larger antelope and wildebeest.

Friend also had a Juenkie--but became a bullet 'junkie', spending a LOT of time fussing with spinning bullets. After a while we agreed that hunting accuracy can be realized with a methodical load and test regimen and factory premium bullets are 'good enough'.

Thanks again for the insight. Great to learn from the experienced 'campers'.

Same rifle used...

I load a 140 ballistic tip instead, and with a load of 44 grains of 4064 or IMR 4895... MV is 2800 on the nose..

If I need a heavier bullet, I go with the 175 grain RN Hornady, with a 40 grain charge of 3031 ( out of an older Hodgdon manual) with an MV of 2650 fps...

the same charge of 3031 with a 154 grain Hornady RN also is a favorite load...MV at 2700 fps..

I have two 7x57's- one Ruger 77 and a Ruger #1. Though I have several rifles in many other calibers, I have always come back to the 7x57. It's my favorite for all the same reasons mentioned by others. Plus, I hate showing up to deer camp with something that everyone else is carrying!I belive I could hunt the rest of my days with this round and not find myself wanting anything else. I have used the 139 SP by Hornady with great success, as well as the 154 RN by Hornady.

Is any manufacturer still chambering a bolt action model in this fine caliber?

The 7x57 was the second rifle that I built for myself,the first was a 35whelen,both on 98 mauser actions.
I had used a rem700 in 270 for a while till I built it,the 7x57 now goes in the case for all hunts.

Don't think so...but a quick search on google turned up a nice almost new ltd. edition (1/1000) Savage over on G-broker (not mine!).

Pretty pricey for a Savage--but I'd guess you could hunt with it just like it is. Closes tomorrow (August 9th).

I will be this for this years WI gun hunt. I assembled this rifle over this past summer. VZ24 receiver, A&B 21" bbl., Timney. Doing the swing safety was more work than the typical wing safety, I like it. Don't have a clue who makes the stock. I was gifted a bunch of Mauser parts, reamers, barrels (all A&B) triggers, stocks, g,ng gauges, hinged trigger guards, etc. First frankenrifle was a '96 swede 6.5x55, nice walnut wood finished w/ spar varnish for my son. Chose doing a 7x57 frankenrifle for me.
Parkerized all the metal, epoxy bed steel to wood.
Shoots aok, 140 Hornady interlock @ 2650fps using imr4064.
Bunch of nice rifles in this thread, thought I'd brag up my frankenrifle smile

Happy to see this thread, as I've posted something somewhat similar

I'm looking to find a single load to which I can tune my iron sights on this 7x57AI project.

Ah yes, my favorite cartridge.

It's hard to beat the Hornady 175gr Interlock for on-game performance. They simply hammer deer leaving a gaping exit. I use those in my old Ruger M77R tang. My other two 7x57s, Flaig's FN Mauser and Ruger M77R MkII, get the Hornady 154gr Interlock.

I almost hate to post load info. The old Ruger handles about 10% more powder than the other two rifles. The chamber is larger and the throat is longer. Not sure about the groove diameter but the difference between these rifles is drastic. For instance, the old Ruger likes 45gr H4350 with the 175gr slug, but the other two only want 41gr before troubles appear.

IIRC, I load the 154gr slug with 44gr of H4350 in the tighter rifles. I shot a deer with the Mauser last year from 300 yards with a stiff crosswind. I gave it 5 inches Kentuky windage and held at the top of the back. The bullet destroyed both shoulder bones and exited. Somehow the deer dragged itself about 20 yards before quitting for good.

I used to hunt regularly with many different 30-06s that have passed through my hands, and still do on occasion, but the 7x57s are easier on my diseased shoulders and kill just as well. The '06 shoots flatter with handloads in modern rifles, but the 7x57 shoots plenty flat enough.

but hey, if it is good enough for Ingwe, who am I to argue with the Grand Poobah?

I was intrigued with the Spanish American War history of the 7x57. It was so effective in the hands of the Spanish marksmen against Roosevelt's troops.

Here are a few pics of my finest 7x57 in a K98.
