Y'all do check the Air gun gate for a thread there, follow all the links and a few "facts" are given.
John

It would be nice to know more facts on how the specified energy is being created...exactly.

What grain, what velocity, what fill pressure?

I would like to see some chrony digits from at the very least, a 5-shot string.

How about some more detailed accuracy statistics?

One thing though, in the few videos I have watched, not once do they fill above 3000-psi, but they do state that it can be filled to above 4000-psi, so I'm thinking filling to 4000-psi every time you shoot it is not a requirement.?.

I think in Rick Eustler's video, they are only filling to 3000-psi. I'll have to watch it again. In their own "long version" video, the again are not filling above 3000-psi.

Still, would be nice to know all of the basics and from all the research I've done, it seems like answering these questions are being avoided, or I'm just missing it.?.

Even a member or more on GTA has got to shoot it, but still no detailed data.?.

I personally am a fan of the product.

Would be nice to see a standard Rick Rustler type review done on this airgun with all the facts and no fluff.:-)

So, there's another company coming out with a "like" model?

Also, I agree, safety and common sense will be of the utmost importance when handling these cartridges, especially charged.

Thanks,

Al.

If I'm understanding Bob's (rsterne) assessment of the amount of limited air in relation to the 28" barrel length, I wonder if shortening the barrel to 23" would help at all, or is that to easy?

Also, I agree with ezman, this company could certainly benefit with having the likes of Bob (rsterne) and a few other GTA Members on their development team, or as Field Testers, as I know that their feed back would be invaluable.

Thanks again,

Al.

I thinks Inovairtech deserves a little slack to get themselves organized. Developing and producing any product is a huge undertaking and can drain countless resources, especially time and money. I don't know size of their company but due to the lack of big names being dropped they are most likely small in nature and may have other jobs to pay the bills.

Of course, it would be nice to hear from them on a regular basis.

Shortening the barrel won't increase the velocity, just the opposite....

Inovairtech llc is on Facebook for those of you who are on there. I see they have been to some gun shows but nothing about production of availability.

I was thinking I would like to have the .257/MAC25, but I like casting my own ammo and the mold selection seems to be very limited when it comes to .257 ammo or boolit molds.

So, the .308/MAC30 is looking better for my personal wants and needs.

Would he nice to cast up to 3 different weights and types of .308 boolits for a MAC30 or .309 and size them down to .308.

All just a dream right now.

Thanks,

Al.

Al, let me add, if you are going to cast, there are no caliber/bullet availability issues. Companies like Accurate Molds are making custom molds for as low as 75$ which is truly amazing for us air gunners

If you can put it on a napkin and have 75$, you're in business!

Then the .257/MAC25 may be a possibilty now.

That's good to know, thanks for the lead.

Accurate may not make molds smaller than 30 cal. but I'm sure there must be others who will.

Lots of molds for the .250 cal out there, I think this gun in .25 would be very nice

blackdiesel · « **Reply #91 on:** October 30, 2014, 08:27:07 PM »

It's also .357. Airgunweb did a review info about it.

We know the current model is a .357. Were talking about the next model or caliber, which will be the MAC25/.257. After that, they're going to introduce a the MAC30/.308.

Have seen Rick's video and look forward to his "facts, no fluff" review.:-)

According to INVT, the bore diameter will be .250 and the groove diameter will be .257 on the MAC25.

Found this list of available .257 molds in various weights, shapes and sizes:

.257 BOOLIT MOLDS:

RCBS - http://www.rcbs.com/
LYMAN (IDEAL) - http://www.lymanproducts.com/lyman/home/
NOE - http://noebulletmolds.com/NV/index.php? ... k41t63lb31
HOCH - http://hochmoulds.com/index-1.htm
LBT MOLDS (custom molds available) - http://lbtmoulds.com/index.shtml

Actually just found several cool articles about the .257 airgun boolits in reference to their shape, weight, size, accuracy and stuff like that. Also found a lot of pictures of cast .257 airgun boolits, pretty cool.

From what I understand, they can be made anywhere from 60-grains up to around 120-grains.

It appears that using the softest lead possible is important, which is great as I already have 5-pounds of 99% pure lead ingots.

Man, I thought that .257 molds were going to be very hard to find, to my relief, I was wrong.

I will wait to see what their test results show when they test various .257 boolits for their .257/MAC25 and then go from there before deciding on what shape, length and weight/s might be best for the .257/MAC25.

Pretty interesting what these .257 calibers are capable of as far as long range shooting goes...if the fps is at least 900-fps to 1130-fps, according to the owner of the Talondor. I think he's shooting 74-grain (LYMAN 257420 Mold) boolits.

Thanks,

Al.

.257 won't work in this gun. The fps will be way to low. The fps is way low for .357. The smaller the bullet the harder it is to make fps. It's all about surface area for the air to push on.

I'm the one that gets the power out of the condors. It takes air to make power and the cartridge is just to small.

Sounds interesting, but it seems the lack of air volume is more the issue than the surface of the boolits, no? I'm asking because a airgun with dual caliber capabilities can push a smaller projectile faster than a larger one.

Bob (rsterne) seems to think that if that could figure out how to clip the air instead of dumping it all, that it might help...based on what he knows about the MAC's cartridges. I do understand the logic of not having a bulk amount of air though and I wonder if what Bob is suggesting would help...if they hold enough air for his theory to work.

I did send a request asking how much air the cartridges do hold and will post answer just as soon as I get one. I was asking because I wanted to have a look at some possible field carry re-fill buddy bottles.

Thanks for the input,

Al.

Without knowing the volume we can't be sure, but Rick Eustler said about 10cc, which is less than 1/10 cc per FPE, so dumping the air as they are doing now is the only logical solution.... The comment I made about "clipping the air" (using timed dwell) referred to using a much larger reservoir, which is not part of this design....

Yes, the same power plant in a dual-caliber gun gets more velocity with the smaller caliber, but more FPE with the larger caliber.... Expecting a 120 FPE gun in .357 to produce that in .257 is, IMO, extremely unlikely.... more like 80-85 FPE.... However, I'm working with so many assumptions I could be wayyyyyyyy off....

airgunwarriors · « **Reply #99 on:** October 31, 2014, 01:42:28 PM »

I would like to make it clear that I in know way expect that the .257/MAC25R will match the Talondor's performance, unless INVT comes up with something or makes some changes that none of us are aware of.

I would be very happy if the .257/MAC25R could push any .257 boolits at 900+fps and it would not bother me at all if it took 60-grain cast boolits to get it done.

Let's just hope that the R&D Team at INVT are paying close attention to what the Wise Men are saying/writing and that they get it figured out.:-)

Respectfully,
