I have been working on my hunting loads for deer. Testing the 140 gr 7mm RM. I have tried three bullets so far Hornady Interbond, Barnes TSX, and the Accubonds.Of the three the accubonds show pressure signs way ahead of the other two. Do you get similar responses from them?

Yes. I had to back off my 378 WBY ans in my 7mm mag...by 2 grains in both

I have found the accubonds to behave almost identical to the ballistic tip and partition as far as pressure signs are concerned.

I too find that the accubonds, the Ballistic Tips and the Partitions like the identical load and there are no signs of more pressure in the Accubonds. The Ballistic Tips and the Accubonds shoot tighter groups than the Partitions.

I had to back off the 200 accubonds in my 300WM as much as a grain compared to my 200 grain partition load. Too bad since the best accuracy came when the primers barely started to crater, and on occasion would crater badly.

Glad I'm not the only one facing this problem. I loaded some 200 grainers in my 300 H&H a week ago and loaded them according to Nosler's data for 200 gr. Partitions. With a max load of H4831SC, I had to do everything short of using a rubber mallet to lift the bolt. Accuracy was outstanding, 4 shots into one ragged hole at 50 yards, but the pressure was to great. I backed off the powder charge by a grain and pressure is OK and will shoot 3/4" at 100 yds. Good enough for hunting the big beasts.

I load the 7mm/160gr in my .280 & the AB shows alittle lessvel./pressure than a 160grNP.

So far I've used the 140 gr. Accubond in my .270 Winchester, and the 200 gr. Accubond in my .300 Weatherby. I have not found them to go over-pressure any more quickly than other bullets of the same weight. I do moly coat all my bullets, so that may affect both velocity and pressure.





I have found these Accubonds to be the most accurate bullets I've ever tried in these two rifles, and I've also found the most accurate load to be the one at max pressure and velocity. In other words, accuracy increases as I go heavier in my loads.

Do they show increased pressure compared to what? They show more pressure than reg Hornady's and Sierra's, less than Failsafes or Standard Barnes X, and similar to Triple Shocks and Partitions.
That being said you should ALWAYS reduce powder charges and rework up when changing bullets. (Which of course I don't always do ).........DJ
