9.5x57 is a mannlicher cartridge. 286gr bullet: 2000fps. A lttle slower w/ the same gr bullet as a 9.3x57. 9.3x57 is one of my favorite cartridges most any game in the U.S. under 150 yards w/ open sights. I'm not sure who makes bullets for 9.5 as they have not been produced by a major manufacturer for many years. There is no Data for the 10.75x57 as it suffers from headspace issues similar to the .400 Whelan. It also never went into production past 10 years. | |||

My 9.5X57 Mannlicher Schoenauer is a pre 1924 Model 1910 take down sporter. I have never heard of a 286 gr 9.5 bullet but only 9.3 bullets (which I use in my 9.3X62). the 9.5X57 was also known as the 375 Mannlicher. I found this in Rifle Load-data http://www.loaddata.com/members/listing.cfm?type=1 & they have data for a 286 gr bullet! You learn something new every day! "When the wind stops....start rowing.

Like Nakihunter, I have never heard of a 286 grain 9.5(.375) bullet. I have a Mauser action sporter in 9.5x57 that I haven't shot in probably 15 years, but if my memory serves me correctly, I think I was getting 2100+ fps with 270 grain .375 Hornady Interlocks. I just looked at my notes and I was using 45 grains of IMR 3031 and a Winchester WLR primer. I'm pretty sure I used 8x57 cases of some sort. Hope this helps. | |||

Thanks for all help. Well, the 9.5*57 sounds like a good caliber, neck to neck with the 9.3*57. Maybe the 10.75*57 is just to much in the *57 case. Jpat talked about headspace problems. Maybe some here use a 10.75*57? Like to hear from them. Cheers all Vegard_dino | |||

Based on what I've read about it, the 10.75 x 57 was loaded with heavy bullets and expansion was hit or miss at the low velocities (well below 2000 fps). It had few followers and didn't last long. That's pure internet commando armchair info. Take it for what it cost you. If that was true maybe newer bullet and powder choices could make it more useful. "Experience" is the only class you take where the exam comes before the lesson. | |||

Yes, I hope so. It is a interesting caliber. Cheers all Vegard_dino | |||

The only reason I own a 9.5X57 is because I got the opportunity to buy the Mannlicher Schoenauer take down model 1910. The rifle is a classic, light & handles like a dream. It kicks a bit with the original profile stock and light weight but is still very shootable. If I wanted a Mauser action rifle I would never chamber it in this caliber. My choice would be the 9.3X62 - which I own in the form of a Simson Pre 1912 sporter with octagon to round full length ribbed barrel. "When the wind stops....start rowing.

I love the 9,3x57 and the only reason I'd consider the 9,5x57 is because in some places .375" bullets are a bit easier to come by. Ballistically, they are twins. The 9,3x62 has the advantage of a good bit more velocity but also of course of being loaded to 9,3x57 specs. One of my favorites too, My 10,75x57 is essentially a rimless .444 Marlin. A lot of fun. No more difficult to load for than a .44-40. A 10,75x68 would make more sense if building.  Aut vincere aut mori | |||

Z1r, thanks for the info. What bullets do you load in the 10.75*57? What velocity do you get? I guess you made that your self? Cheers all Vegard_dino | |||

I have been loading cast 300 grain bullets sized .426". My bore is slightly oversized. the rifle was not made by me but by Gustav Genschow & Co. I use .444 marlin data and load to right at 2000 fps. I can squeeze out more but it is plenty of fun to shoot. With 350's I can get near 2100 fps. I have shot some Hornday 265 grains flatpoints, these worked very well and would make a heck of a deer round. Aut vincere aut mori | |||

Z1R Thanks for the information. Have you hunted with it? Cheers all Vegard_dino | |||

No, not yet. But it would make a dandy Hog thumper! I really wanted to convert it to 10,75x68 but I'm tiring of having to ask relatives to get me RWS brass from Germany. I'll leave it as-is. Instead, I'm building a .404 or 10,75x73. Aut vincere aut mori | |||

Yeah, great short range hog thumper it is. Guess it will make a good short range moose, bear and so thumper to. Did not know RWS made brass for the 10.75*57. Makes it more tempting to have one...  Cheers all Vegard_dino | |||

I don't believe RWS does make brass for the 10,75x57. I was referring to the 68 which is why I decided not to build one. For the 10,75x57 I use Norma 9,3x57 brass. Aut vincere aut mori | |||

I understand. I was thinking the same about 9.3*57 brass. Thanks for helping me. Cheers all Vegard_dino | |||

I compared the specs for the 9.3 & 9.5 X57 cases and found that the length at shoulder was the same though the taper was different, So I got some Norma 9.3X57 cases and plan to fire form them in my 9.5X57 chamber with the usual precautions & bullet seating. I also got some formed cases (from 35 Whelan brass) fro Buffalo bullets in the US. "When the wind stops....start rowing. When the wind starts, get the sail up quick." | |||
