Three bullet selection

Have finished testing three 6.5mm bullets and accuracy is all the same, .5 to .75 moa.

130 Accubond / .488 bc
127 Barnes LRX / .468 bc
130 VLD / .552 bc

Assuming identical hunting conditions of 7,000' elev, 30 deg F, 30% humidity for Western Montana for 1st week of elk/deer season. All 200 yd zeros. The following is presented at 670 yds, the range at which the lesser effective bullets will pass 2000 fps for dependable expansion. The 1800 fps range is shown for those who push the manufactures reliable expansion speed to the limit.

Bullet........1800 fps.........2000 fps.........600 yd 10 mph fulll value wind......

130 AB .....870 yds..........670 yds..........18.04"

127 LRX....850 yds...........670 yds........19.34"

130 VLD.....1130 yds.......910 yds.........14.4"

These are not apples to apples starting velocities. They are the real thing from my rifle. I am confident and proficient with all three. Just asking for your opinion on which bullet you would use, or not, on a mature Montana elk, whitetail or mulie and what you might expect for terminal effects. I didn't give drops since drop is too easy to adjust for it quickly in the field. All three stay within .35 to .67 moa for vertical.

Re: Three bullet selection

The 127 grain Barnes LRX is actually rated down to 1600 fps for expansion so you could say 1800 would be a safe bet. I would go with the barnes as it will definatly penetrate more than the berger on an elk in case you have to take a quartering away shot, but it is rated for lower expnsion velocity than the accubond there for increasing range.

I would pick the most accurate bullet and limit it to the 1800 to 2000 ft/sec distance for traditional
shot placement.(Behind the shoulder).

If a shot presents it's self beyond the 1800 ft/sec distance then in order to get proper expansion
you should change the point of impact to hit some bone or the spine. (This is the reason for the
best accuracy) Hitting a smaller spot.

Shot placement is probably the most important factor to consider based on the game hunted and/
or encountered.

Re: Three bullet selection

I think your testing answers the question for you. I will always go with more expansion and les wind drift for a long range bullet. Bullet placement is king (as JE said) and less drift makes this easier.

Good job with your testing. You did it for a reason, I would go with it.

Re: Three bullet selection

Very nice! Seems like all three are winners really. That Berger is pretty slippery, but for me, I would want the AB or Barnes, just for the times when an elk pops up closer than longer ranges. That is just me though, if you are primarily hunting where long shots rule all the time, the Berger looks like a winner, but my elk hunting is a little more of a mix of timber and moderately long shots.. So I go with the tougher bullet. Seems like some great testing!

Re: Three bullet selection

Heading out this am to test each one @ 700 yds. I've got a spot up the canyon behind my house where I can get 950; maybe 980, but I moved the steel 1/2 silhouette in to a bit over 700. I want to see how each one matches up with my Leica 1600-B LRF. Will report back with results and choice.
