Re: VLD\'s, ULD RBBT\'s, SMK\'s, etc

You will be fine, again, sectional density is very high, you will loose alot of bullet weight on close range impacts but you will get through the vitals in most cases.

Again, the SMK has a thick jacket for a match bullet and thats a heavy bullet.

Must be shooting her out of a RUM????

SES- No worries, we are all here to learn and it is all relative.

Bob- Nice to meet you too. Okay, now only 1 person.

Kirby- I wasn't sure if some of them had actual velocity ranges or not, just thought I would ask. I think that I am understanding you correctly on what you are saying about these bullets. The tougher(thicker jacketed, higher SD, heavier) that they are, the more they can resist just turning to dust on impact. Yet with Accubonds, the tips help start the expansion at the slower velocities way out there. Do the new Wildcat bullets fall under this as well?

As always, thanks again everyone for helping out a fellow sportsman.

Metau,

The wildcat bullets can be ordered with different jacket thicknesses and also in many cases, with bonded core designs.

Some of then are basically the same as the Berger VLD bullets as they are also made off the J-4 jackets.

Others use a tapered jacket that is thin at the mouth and gradually thickens in the bullet body area of the bullet.

Others still are made off very heavy jackets in the 30 thou thick range which is extremely heavy compared to most conventional cup jacketed bullets.

Simply put, they are custom bullets made to your needs or at least you can select a bullet that covers your needs well.

The tapered jackets would be the best overall choice.

Yep, 300RUM. (Wish I was launching 'em with a 300AX!) Getting right at 3K with Rem brass and a few fps slower with Nos brass. Still experimenting a bit. Might do a bit of a write up regarding my experience with Nos vs. Rem brass when I get the data from thowing a few more downrange.

"Yep, 300RUM. (Wish I was launching 'em with a 300AX!)"

I think I know someone that could remedy that wish!!! /ubbthreads/images/graemlins/grin.gif Just tested that bullet with Retumbo in my 300 AX the other day. Retumbo seems to be a bit to fast in burn rate as I topped out at around 3125 fps with the 240 gr SMK. WC872 topped out at 3220 fps but that was because I ran out of powder capacity with 119.0 gr!!!

I think US869 may be just about perfect, just want to get into that 3200 fps range with good top end pressures to keep things burning clean and efficently.

Retumbo topped out at 97.0 gr which leaves more air in the case then I like. That said, I shot this load a bit at 900 yards and she was holding well under 3/4 moa in a 20 mph wind from my 8:00 position. I am sure it would hold 1/2 moa in good conditions.

Anyway, you will not have any problem with the 240 at around 3K. I would not intentionally try to take on a shoulder knuckle at 50 yards but I would bet if you did you would get your elk just fine.

Imagine a heavy jacketed 215 gr Aluminum tipped RBBT with a BC WAY higher then the 240 gr SMK and with a 125 fps velocity boost as well!!!

They are coming!!!

I want some!
I want some!

I think. Do you think they will stabilize in a 1 in 10 twist 300 RUM or 300 WM?

I shot a test load of 240 SMK and got a beautiful group and SD and ES that were 1 digit. and then the next time I went to the range with a slightly increased powder charge the bullets printed sideways on the paper. The temperature had gone down about 20 degrees. First ones were shot at ~70 and these at ~50. They were running around 2600 f/s. These were in my 300 RUM. I have not had the time to get back out to the range and try the next series of rounds I've loaded. So my load development has come to an end for now.
 
Re: VLD\'s, ULD RBBT\'s, SMK\'s, etc

I'm shooting Rem brass and 105g US869 under the 240SMK for just a tad over 3K fps in the 300RUM w/26" barrel. Gotta shoot 'em faster than you are so they won't print sideways and you can get away with using the 240SMK in a 300RUM 1-10 twist out to about 1500 yards (destablize dramatically at that point) is the experience on the board here. This is a cool weather load--don't try 105g at anything about 50 degrees just to be on the safe side.

From what I've heard from Fifty and Richard most of those Al tipped bullets will require either a 1 in 8 or 1 in 9 to stablize. Richard did tell me that he thought a 190g .308 Al tipped version he was working on would stabilize in a 1 in 10 twist.

I am new to this forum and I have a ? what is a RBBT and a ULD.... this may sound like a stupid ? but I have no idea what these are. I am an avid long range shooter (I thought) and shoot a lot of Berger210s and have tried all the SMKs. My favorite long range rifle is the 30 Hart pushing the 210s. I shoot 1000-1200 yds with this load weekly with great results but am very interested in these new (to me) bullets.
