Very odd looking bullet

7x57mm Mauser (7mm Mauser)

173 Grain Soft Point Cutted Edge

Ever seen something like that?

Remember: Four boxes keep us free ,the soap box, the ballot box, the jury box, AND the cartridge box

HUMM.

I can't find any for reloading.

I must have less "Friction" going down the barrel too. Interesting. I think a 170/175 sst is more to my liking.

I have 6 boxes of them factory.

Just a question, If a person had a 7x57 AI it would just be a mater of firing factory shells to make the cases correct?

Thinking ahead for our maybe up coming rifle project.

PS we would use 140 ish for the GD. Shocked

tough to beat tw Hornady SST design.

D, if it is a true Ackley cut chamber then you should be able to shoot regular 7X57 factory ammo and have AI brass. Ackley designed his improved chamber to be able to do this specifically. There are many variations to the "AI" chambering, but from what I have read, they all should be able to be fire formed.

AI cases have two advantages: more case capacity and less bolt thrust. They get that by making the case body straighter.

They is some of these advantages in any case change; but anything really significant is in highly tapered cases; LIKE 30-40, 300 H&H, 303 Brit, 25-20, etc You will notice these are all old designs.

Most modern cases have been originally designed as small body taper: 308, 243, 270, etc. so there is little to be gained by making them AI; they already have the improvement. Any perceived gain in velocity is usually from loading them way above standard pressures. Wildcat cartridges do the same thing; as there is little published data for wildcat (or AI) cartridges. One can easily overload standard cartridge to higher pressure and get higher velocity. there is no free lunch.

Thinking of AI designs, the case is stretched as the sidewall is longer, so it must be thinner, which can reduce case life.

P. O. Ackley was a gunsmith, and he wrote for Guns & Ammo magazine, great articles. he has two excellent books that explain the AI approach.

Just thoughts.

	Yep, S&B aka Sellier and Bellot they call it an spce. Soft Point Cutting Edge bullet. The cutting edge locks the jacket and lead core together, while also producing a clean entrance wound and distinct, easy to follow blood trails. Appropriate for light to medium game. They make it a number of euro cartridges. in 7x57 and 8x57 I've used it on whitetail. Also comes in 7 rem mag for the usa crowd! 7 mm REM. MAG. – SPCE (V332762) – 173 GRS – Sellier & Bellot (sellier-bellot.cz)

	I've never seen them before. Bears explanation of how they work makes sense.
	I have always considered myself to be quite the bullshitter, But ocasionally it is nice to sit back and listen to a true professional......So, Carry on.

	"tough to beat the Hornady SST design." We use a lot of them. Some day we may get Barnes bullets back and we will try them too.

	YES that's all you do easy. The chamber will be cut to Saami specs as well as the dies from reding. We normally only neck size fired shells till we have to bump back the shoulder or have a problem chambering. A BIG advantage of an AI chamber is it almost STOPs case stretch and having to trim. the D-I-L has a 280AI and that's all we do with it too. A lot of time you can even still hunt with the bullets as you fire form, as in the same poi. My 8 when we use 375 H&H brass we do have to neck it down then fire form, it shoots at 200 yards to the SAME poi. If dies were not SOOOO expensive we would AI all our chambering. You Don't have to load to the max even if you have more case space. The boy HATES trimming cases. I just watched a Video making a 7x57 out of 270 brass, it looks easy too. trim the case shorter neck it down load and fire, poof new brass. I would bet an '06 would be the same. A 6mm rem I think you just have to expand the neck and size and shoot. Edited by d4570 - 03 March 2023 at 08:12
