AI that sumbich and we'll talk....

HS, I did just that, spent a bunch, but in the end not sure it was worth it.... Shot well, was a little faster, but the 7x57 is 'just right' as it is.. IMHO.

If I end up with another '7' it will probably be a x57 NOT AI'd

Mike, have you tried working with Re17 yet? I get excellent accuracy and some really great velocity with the 150 gr. Nosler Partition. I'm talkin' .50 to .75" groups and 2800 FPS+ for velocity. The same load does MOA and about 2760 FPS from a Ruger #1A. The only rifle I'm still having trouble with is the custom Mauser that has an extremely tight chamber.

I'll be doing some work with the Mauser once my doctor clears me for shooting. I have fired a single shot this year thanks to an accident in my truck where my chest got banged up a bit. I see him again next month and I'm gonna push it. I'll go shoot after that whether he OKs it or not.

The plan is to run some factory ammo from the M70 and the Mauser over the chronograph to see the actual difference. I did do a short run with what few 175 gr. Hornady RNs I had left, loaded to duplicate the original 1892/3 load. The Mauser ran roughly 150 FPS faster at 2450 FPS vs he 2320 FPS average between the M70 and Ruger #1. Still trying to figure that one out.

Some people just can't leave well enough alone.

Try Ramshot Hunter

I have not, but I'll give it a whirl. Thanks for the suggestion. Hope you're on the mend.





I've used it and Big Game. Neither would do squat with the 140-gr Partitions, although the rifle shoots heavies really well with Hunter.

A 7mm round at said speeds is truly a ballistic sweet spot ... coupled with a recoil sweet spot. With short action options. What's not to like?

Sheesh, EVERYTHING can't be a 6.5 Creed ...

[sound of umbrella opening]

I this day and age,I'd go 284 Kreedmire,over BR.

Hint...............

"I haven't made any very long shots with the 7×57, but I try to avoid long shots with any rifle. Most game is killed at 200 yards or less, but many of these kills get stretched out when they are processed through a typewriter."

Love this guy.

It is not so, that the .270 Win. and the .30-06 are not just so.
As are the 7mm-08 and the .308 Win. so so.
Now, while the 8x57 is being more so, it is just so,
that the 7x57 Mauser is just so much more, just so.

Thank you for the article.

Rev Mike my buddies's 1A didn't like anything either till I handed him a box of Super x 175 gr RN's. My 1st year production m77r has the same long throat the 154 hornady rn works well also. MB

I've seen you mention that AI'd 7x57. I'll admit I'm jealous. I don't know if I understand what you mean by "just right". I believe in certain velocities for certain bullets at certain ranges, I believe in reamer specs that give the bullet a good head start, and I believe in case efficiency relative to bore size. In my estimation, the 7x57 AI with the right reamer specs covers those bases pretty well. I should add that I'm not a fan of case taper. It means I'll have to lose time and brass through trimming, and I just don't have time for that anymore. An AI'd Mauser case in a standard-length action with a minimum but long throat so that long bullets are in the neck rather than in the case, and that comes pretty close to Western hunting perfection, given today's affordable bullet, optic, and LRF tech.

To each his own though. If I lived in Florida, I'd likely agree that screwing around with an AI just isn't required. I did live in Florida for a short time in my 20's and what I saw for possible hunting didn't require anything special in regard to cases, bullets, optics, or range finders.

I figure I've been healed up for at least two, maybe three months. Sternum cracked in four places and breathing hasn't hurt for months.

I have two pressure series loaded up for the 7x57 and I'm anxious to run them over the Chrony. Then there is the test to compare factory in the Mauser vs the M70 to get an idea about figuring out the problem with the Mauser. It's too late now to even try to book an elk hunt but I'll cal the outfitter after I get to shooting again and see if he has any last minute cancellations. Who know? I just might get lucky.

The 175-gr RN is one of the bullets this particular rifle actually likes.

I haven’t had much luck getting 140 partitions, 139 or 154 interlocks to do well in 7 anything. This is difficult for me because interlocks shoot great for me in everything else and usually what I reach for. When I want lighter in 7mm, the Speer 145 hotcor has been a consistent standout in 7x57, 7-08 and a couple of 280’s. The 150 and 160 partition do good as well for me. I’ve pretty much settled on 145 hotcor for deer, 160 partition for bigger stuff when needed. Do have an itch to try 145 LRX’s though. Going to wait until I see how the 129 LRX does on game in my 270 first.

Mike check the throat length and adj your seating to work, works for me. MB

Always a great read!

40 years and still the little guy !

When will it grow up ?



Just joking, couldn't help it.

It is all grown up,it's just a welter weight that hits like a heavy weight.

That's pretty much the procedure I'm going to follow. I have some four-round lots loaded with I4350 and the Tipped Match Kings in .5 grain increments. They're loaded .10 off the lands. Once I find out which is the most promising I'll start reducing the CBTO length. We will see what happens. The thought has gone through my head that as a last resort I'd send it to Hill for a complete make-over, but I can't bring myself to justify spending $1700 to do it.
