Re: 375 Snipe Tac...Barrel and Bullet tests

We are working with not only Sierra Bullets building our .375 Match Kings and possibly Game Kings, but several other bullet manufacturers on heavier .375 and .408 expandables, even .338 expandables which are known as the 338 CheyTac. We don't improve shoulders, etc. on the brass. U.S. and NATO Military frowns on that. It is simply a .408 case necked down. Same bolt face, magazines, etc. on any of the three cartridges.

We leave the "Neck Improving" chores up to Dave and Kirby! Those two guys do a fabulous job, as I've dealt with both of them for years. They are #1, and we will continue to be there for any wants and wishes they may have as best we can. Those 2 guys continue to "push the envelope".

A .408/400 grain Hornady SST is very close, and may probably be the next .408 Cal. bullet produced. But there are some manufacturers producing .408 solid expandables right now that shoot very well, perform very well, and have a very high B.C.

Solids are more expensive than lead core bullets, but adding both lead core and solids to the line of .408, .375, 338 availibilities is a win-win situation at this time.

Hey Kirby,

The Hornady SST, right now, is scheduled for a 2/09 "Shot Show-roll out"). It will only be in a .408 offering..... If everything goes as planned, and as I'm told.

I have some solid expandable .408/420 gr. bullets that absolutely shoot "Lights Out" and very sub-MOA. Those were just prototypes at this time. They grouped great for me, and expansion was extrodinary in wet phone books, Obama magazines, etc.

I shot some .408 lead core bullets that "key holed" every shot from 25-100 yards. Those there, were USA made. They came apart with a 1x13 twist rate doing 2900 FPS at 25 yards.

Just an update Kirby. Hope you are well.

Sorry If I'm not on this site that often. You know what I do. We train here and there, and I'm out of CONUS some times.

As you know, I withhold opionions on nothing. Tell it like I see it. My goal is to get the best sytems I know of, into the hands of the guys/operators that require/need it today. I tell it like I see it, and would not approve rifles for Combat unless I would personnaly take it there myself, or send it to my son. That is my mission.

I have but that ONE philosophy....

..and have worked at CheyTac since it's inception with Dean Michaelis as shooting partners for way too many years!

But...beinging an Observer/Shooter (and don't ever say Spotter in Deans presence) for Dean for many years, I got to welcoming his "tirades" in the field. I wish there was more of his kind, with that kind of experiance out there.

Take care,

Dave D.

Re: 375 Snipe Tac...Barrel and Bullet tests

Dave,

That is good to hear about the SST option coming. Will these be a regular catalog item of special order type thing, Ya know, the type where I have to call you to get them!! LOL

Lead core bullets certainly have their challanges and issues for sure. Its my opinion that when bullet gets to these weights, and you drive them to these velocities, its much harder to keep them together then a smaller diameter, lighter weight bullet. Jacket thickness is critical to success.

Ever think we could talk Nosler to make us a 400-420 grains accubond!!! Doubt it!!

Totally understand you being busy and not able to get on the board much. Thats just a good sign!!!

Hey Dave,
Long time no talk!!!!

I have to say the new 375 brass is working great! Seems the guys in Sturgis got
the problems worked out, good job! Let me know when you get some bullets to test.
Any caliber will do. Keep up the good work.

Dave

Re: 375 Snipe Tac...Barrel and Bullet tests

For those interested in the progression of the banded solids. I recieved a sample of the 30 cal variety. There were two versions, one was brass and weighh 181.5 gr, the other was copper and weighed 190 gr. I shot these out of 10 twist standard barrels. The first were shot out of a Broughton 10 twist .308. These would not stabilize at 308 velocities. I then fired them from a stock Remington 700 300 Rem Ultramag 10 twist barrel. They did marginally stabilize at around 3000 fps. Computer programs are suggesting a 8.3-8.5 twist will be needed for optimum performance, I am in the process of obtaining a gain twist 1/8.5 barrel and we will know a lot more about these bullets very soon. Also I posted earlier that someone will introduce a banded expanding hunting bullet that will be a clone to the solids in every respect except it will expand. I felt sure it would happen at some point but I did not expect it to happen so soon. It appears there may be an expanding version that will be available even before the testing is complete on the the ones I have now. I have been asked to not discuss specifics but it is not a two piece bullet and the performance will be identical to the non-expanding versions. The hunting bullets will be higher in price but all practice can be done with the cheaper ones. The first bullets as stated weigh 190ish but there is no reason that they cant be longer and heavier with BCs off the charts. Get ready for the era of the long stroking single shots with gain twist barrels.

Augustus:

Wow!! You are talking performance that blows away everything we have now!! If these bullets are so long they need gain twist barrels, we must be talking bc well above 1. I know you have talked a bc of 1.5 before. I'm going to run that again thru JBM and put all my plans on hold.

And expanding solids that shoot like the normal solids!!!!!

I did a quick check on JBM. A bullet with bc of 1.5 carries 2/3 of it's initial velocity to 2000 yds at 4500ft elev. So with 3000fps at muzzle you still have 2000fps at 2000 yds!!!

Please keep us updated.
