Rose vs Afterburner

[cohunt]

So I recently bumped a few threads on both the a.b. and rose bullets to see how they are doing in the field

The way the bullets work are using 2 different technologies

The a.b. looses it's nose fast and leaves a flat faced, deep penetrating slug

The rose (with its mythical hidden hollow point) mostly retains it's pedals for a larger more mushroom like slug

People that have used both in the field--- how would you compare terminal performance of the 2?

How do bc numbers hold up?

How easy are they to load?
What kind of speeds are we seeing?
Other info to pass on?

Just trying to compare 2 higher bc mono's to each other--- even thought they may be apples to oranges

Would be interesting to see how all these designs with different wounding mechanisms compare & contrast. Mushrooming vs fragmenting for example. I fear though, one needs to test them in a manner that can produce reliable and unbiased results. I know gel isn't the same ratio of medium that meat is, but for comparisons sake, it could be beneficial. I think observing, measuring, (sciency stuff) of the terminals like temp cavity, permanent cavity, penetration and predictable wound path would be the best.

I did see a Vortex youtube channel where they identified a big difference between the popular clear gel vs ballistic ordnance calibrated "yellow"ish gel. (The FBI test gel) Ultimately, getting a constant variable ratio to apply between gel and game would be the most ideal.

I'm more of a shedding the nose fan than mushroom. But the terminal thread on the McGuire looks good. I believe Fordy will be, or has tested both these bullets. Maybe he will share his findings.

From what I remember seeing in the terminal performance thread, is that more times than not the McGuire has shed its nose. Design change? Or perhaps not a low enough impact velocity to only mushroom.

I will be testing some 160 Gr copper rose out of my 7 PRC tomorrow morning. If they work out, I will shoot a javelina in March at distance and see how they do on a smaller animal. If I like the results from that, it will be used on elk this season.

We've seen some "pedal" shedding with this one as well. Velocity based results.

This is a well timed thread as I was looking at testing these bullets out myself. Following!

Comparing weights and min expansion velocity for the "old" standard of twist rate

McGuire- 7mm (1-9.5) 143gr (2200fps)
308---1:10 tw-168gr ( 1800fps)
and178gr is 2200fps

Apex Afterburner: 7mm 117gr (1650fps)
.308- 153gr (1650fps)

So the rose are more "normal" weights 143/168/178

The AB are lighter but by design seem to expand at much lower speeds

These do have higher bc numbers that other mono's but I'm usually a "normal to heavy for cal" kind of guy--- they usually retain speeds and energy better for the longer shot opportunities


What kind of speeds are guys seeing with all these pills?




Waiting for @fordy to chime in on any comparative testing he has done too, but anyone who has used them on game please share good or bad results

I plan to test some McGuires next fall, if I can. There's a lot to do between now and then with a stupid deployment in the middle. Luckily its a short one. As long as I can get a load worked up before I leave, I should be back in time to use it for our deer season. If I can get a load worked up quick enough, I could maybe test them on coyotes first. We shall see.

I'm quite interested in how they compare and contrast as well.
