One trick I learned with my .300 WM. I worked up RL-22 loads for the 180 NBT and 180 NAB. They both have the same shape, same B.C. and same POI in my rifle, one elevation turret for both. I can choose bullets according to the critter I'm gunning for. I found that the NBT's were a hair more accurate than the NAB's, both shooting extremely well.

Here is a Long Range Accubond, 150 gr .270 that we found in the off side hide on my brothers blacktail...2900 fps started velocity,range 200 yards..... High shoulder shot that hit a lot of bone... Nice looking mushroom that weighed 65 grains...

Just a "for your information "post:. This is what it was and what it did kinda thing..

Not really. While part of it is that almost all bullet are designed to work properly at the normal 2,800-3,000fps range and not the 3,400+ range, mostly it has to do with what bullets are used. Using your example of an 80gr Barnes at 3,600fps- that bullet just doesn't create as big a wound as most bullets that are used in cartridges in the under 3,000fps zone. Given equal- none CNS impacts, equal impact velocity and adequate penetration of the vitals- softer bullets that produce secondary wounds from fragments create significantly bigger wound channels and this kill faster.

Hard bullets with marginal shot placement and/or high lung shots produce relatively smaller wounds and bleed less. Couple that with extreme impact velocity where the bullet will shed its petals and the wound channel gets even smaller.

Shedding pedals is fragments that create secondary wounds.

I'm looking for ideal 6.5mm 3,400 fps bullets. The 140 NAB is for sure a contender and when I can find 129 ABLR's, I'll try them.

Berger Hunting 140's, reportedly, shouldn't be pushed beyond 3,200 fps. Berger's 26 Nosler 140 Hunting VLD load is 3,100 fps. In email correspondence, they admitted their 140 Target VLD with its slightly thicker jacket may be a better hunting bullet at full house 26 Nosler velocities.

Matrix has a nice offering of VLD's and bonded hunting bullets. I'm going to check them out, as well.

I appreciate the tips and info.

Yes, but very few, and in the case of Barnes- a max of 4. Far cry from dozens if not potentially hundreds from some bullets. Barnes are good bullets, but not perfect nor are they the best for every task.




DF,

If it were me and I wanted damage on deer sized game I would start with both Berger 140gr VLD's and Hornady 140gr Amax's. Just don't expect exits at close range especially with the Amax's, though you'll not have to look for the animal...

The smaller the particles the less momentum and less distance they can travel.

I've used the old 130g AB's in a 6.5X57 Styer, perhaps a tad over 2800fps, never recovered a bullet, but the deer went down with a good size wound. Close range longest perhaps 75 yards. Have a new CZ full stock in 6.5X55, seems 6.5mm bullets are hard to come by right now. Will try them and Hornady interlocks and perhaps some Bergers.

I also have Scenar 139 and 136L, both reportedly good high vel performers.
