300 RUM with 220 partitions

[OU812]

Yes I believe it would with 26 with little issue but 24 is what I have. Glad your's will do that speed with 24, kind of encouraging.

Yes, I am so glad mine is doing it and I am still in awe of this big 8, just a real cool rifle and cartridge.

Could not agree more. I have not given the accubonds a fair shake and never tried the Partition. May have to do so and see what exact speed and accuracy I can get.

It's an under rate round with LOTS to offer in the big game world.

The 300 RUM with a 220 gr bullet is what a 338 Win mag ought to be like. You can't overkill an elk . I kind of like em over easy.

Awesome!!! That is to funny Greg, just to funny :lol: :lol:

I have been reading Brian Litz's book and he actually ran through alot of the common bullets, the actual BC difference between the 200 PT (.493) and 200 AB (.523) isn't really a whole lot. Kinda made me think the 200 PT would be a viable option in the 300WSM for this year, if it'll shoot.

Scotty the BC for 30 cal 200gr Partition is .481 while the AccuBond in the same is .588

Bill, I pulled the corrected numbers from the "Applied Ballistics for LR Shooting" by Brian Litz. He went through and tested about 250 different Hunting/Target bullets using Doppler technology to get the true BC of the bullets out to a 1000 yards. It is actually pretty surprising how off some bullets are and how close as well. It is a well written book that gives a ton of information and the testing is done to get truer numbers for input into the programs. Most of the PT's are pretty close, but the AB's seem to be off a touch more. Either way, it all probably comes out in the wash.

That is very interesting Scotty and thanks for correcting me when I tried to correct you . Wonder if the advertised BC's EVER came up in his date collection or where they just fudged to sell bullets and the ave guy would never know?

Bill, I think Brian Litz mentions the only real way to test bullets true BC is to use some kind of expensive Doppler system, or to measure the timed distance at longer ranges. Lots of manufacturers just estimate bc from computers and short range testing, which doesn't assist much as BC changes through the velocity spectrum (and claim exagerated BC's which are somewhat true, at the short ranges tested).. I am not trying to sound like a know at all on this, just what I have been learning from his tests. His books and alot of math is way above my head, but it is good info and still useful for predicting my own trajectory and becoming a better shooter.

Never a bad thing to try and better oneself.

Digging up an old thread...but was just curious if this was here...some of the Nosler BC's Litz tested can be found in the following link.

http://www.dtic.mil/cgi-bin/GetTRDoc?AD=ADA554683

I have found that the 168 BT has an actual BC of about .470 (advertised at .490)...did that just using a chrono at 100, 300, and 600 yards...not sure how accurate that is, but it made the numbers match on JBM...and .470 is pretty darn good for a 168 grain bullet, Bergers VLD 168 grain hunting bullet is just .473.

Based on this...I have decided the 180 grain AB is a bullet that I'm gonna try in my 30-06.

Also, this reinforces my belief that Nosler should make a 168 grain AccuBond...

You'll like the 180 AB. It's an awesome bullet.
