Upcoming testing project****TEASER*****

Registered Users do not see the above ad.

I read a thing that got my blood boiling again.

The PRS world is a-blaze with more voodoo again.
A new 155.5gr bullet with the BC of the 190-200gr class, that can purportedly push them in the 125-130gr class. All magically while not running high pressure in the 308.

Unlike the creators of the "new hotness" we will actually be using Pressure Testing equipment. There will be no "Hey, the primer didn't blow, so I must not be running high pressure!".

Can you get those velocities without "Classic" Pressure signs? Of course you can, we've already proven repeatedly (and weren't the first to do so) that primers and brass do NOT accurately report pressure.

But can you get those velocities from SAAMI 308 pressures?
Stay tuned for the results.

Stabilizing these bullets?

For talking so much smack you'd think they'd show some actual field test data! They mention the extreme length of these bullets but, funny that they forgot to mention anything about stability and necessary twist rates!

From what I see is a bullet used in competition only. With the extreme length I assume no one who owns 30 cal sporting rifle will have a fast enough twist to stabilize this bullet. So those with 30 cal sporting rifles won't be able to use this bullet. This makes this bullet very specialized .

Don't recall if it was on Warner's site specifically now, but they do list the required twist lengths somewhere. If memory serves, all but the heaviest 30-cal is supposed to be stabilized in a 10-twist.
What I don't know yet, is if that is predicated upon running extremely fast velocities, or not.

I will say that when I spoke with Mr. Warner this morning, he is a very nice gentleman. Was very polite, and helpful; offered several things about loading. My original unfavorable reaction about the Hype surrounding these bullets still stands, but I do hope he sells a mountain of these. He was very good about repeating several times that he has NO pressure testing to substantiate any of the load info about them.

They should ship today, and I'll get a few measurements on them before sending them south for Pressure testing.

From your photo they are definately in the long and slippery looking category. From the "looks as though" deal I'd suspect stability issues with a 1/10 tube with normal 308 velocities. Guess testing will tell.

Looking forward to hearing the results.

That line up is a good pictorial example of were the ogive sits in relation to the rest of the bullet.
I would like to heare some experianced views on what is seen and expected when new bullets with an ogive so far back come out.
I would be surprised if I am the only one with all the opinions posted about preffered lands to ogive distancess.
I didn't think Darkker would mind the thread being borrowed while we all eagerly weight for the results.

Doesn't bother me. I'm hoping to get part one done tomorrow(I guess that is now later today), so bullet measurements velocities and some groups. Pressure testing, specifically with the suggested 4895; will come later once I get some shipped down to MZ5.

Good luck with your testing later today. Me, I am up early to head to the range with my son-in-law to help rebuild target boards at the range where we are members. Then maybe some shooting to "test them out."
