So then my next question on the performance you experienced is what were the impact velocities on the game animals you hit with the Accubonds out of your .300 RUM? As you know well, muzzle velocity is one thing, but what actually matters is the actual impact velocity on the animal at 200 yards or whatever the distance was.
I am not arguing or disagreeing with what you said, just trying to establish a better frame of reference.
I do not shoot any of the RUM's or the Nosler chamberings. Had a 26 Nosler at one point and got rid of it. Too be honest when I thought about it after reading your post, I don't think I have ever used an Accubond our of anything that is a high velocity chambering. No real reason for that other than I have been shooting a lot of monometal offerings in recent years and that is what I usually had in the fast cartridges.
I have used Accubonds in the .270 Win and they have always worked great...that being 130 or 140 grain bullets at their respective velocities. Also 165 grain in a .30-06. The 225 grain bullets out of a .338 Win Mag and 260 and 300's out of a .375 H&H. So I have not really strained them with ultra high velocity cartridges...they have always had E-tips, Barnes, CEB or Peregrine leaving the barrel.
I have used the A-frames a fair amount over the years...when I could get them...but again out of more "moderate" chamberings when it comes to muzzle velocity. They always do what they are suppose to as those who have used them a fair bit know.
The impact velocity was on the higher side..I had those 180s going 3370fps..shots in Afica are much closer than most of what I do here in Montana..would say they were 150 yrds or less..some much less..
I shot an impala one day fore leopard bait and blew the fetus right out of the doe..
First animal I shot was a waterbuck..took for shots to finally put it down..it dropped on every shot and got back up
I have had very good results in my 280AI with the accubonds..but.. also much lower velocity and most shots are 300 yards or more..the last Ibex was 430 ..
Well I doubt I have on my personal hunts or with clients I was guiding, seen impact velocity with Accubonds that exceeded 3100 fps. My closest impact velocity was probably from around 3100 fps with a 110 grain Accubond out of a 25-06. It certainly seemed to have performed as expected on a mulie and exited the off side. Outside of that particular instance I doubt I have had more than a handful of impact velocities that exceeded 3000 fps and most have probably been down in the 2400 to 2900 fps from the various cartridges I have used them in.
It would be interesting to hear of others experiences with impact velocities exceeding 3100 fps. For the most part, when I have recovered Accubonds they were nice mushrooms and had weight retentions that were similar to what you would have for weight retention with their Partitions, as has been claimed by Nosler. Of course the Partitions are not bonded, like the A-frames, but with the partition they generally turn in weight retentions of around 55 to 60% with the entire front portion of lead core gone.
Generally I have leaned towards full monometal bullets or monometal rear shank bullets like the North Fork or Trophy Bonded in recent years. For the most part they offer high BC's and you can drop back a notch or two in bullet weight and have higher muzzle velocities.
And on that note, I am getting ready to order some of the Hammer Bullets to give them a try.
So many bullets to try these days that you just can't keep up with it. Not enough time, money and in many cases you cannot depend on availability.
