I shot the Swift, Accubond and Barnes 7mm bullets in a comparison from the same rifle, same brass same day, same load, same, same , etc. 7mm. test was 3/4 plywood soaked in water for several days and ballistic gelatin behind the plywood. The load was above average due to the rifle being freebored and the bullet seated to longer than sammi specs. I PUSHED THESE HARD. Impact was at 25 yds, 300 yds, and just short of 500 yds. The Barnes penetrated the most at all ranges. At 25 yds the Barnes ripped 3 petals off and the bullet tumbled through the gelatin. The Swift was ripped apart and was in pieces, no measurable weight retention, 20% of the penetration compared to the Barnes. The Accubond was 25% weight retention with 60% of the penetration of the Barnes. 300yds . The Swift had 70% weight retention and had a nice cavity in the gelatin. The accubond had 83% weight retention and penetrated further than the Swift. not much but 4in is 4in. The Barnes 100% weight retention and penetrated the most. 500yds got real interesting. The Barnes again penetrated the most and had 100% weight retention, sounds good but the wound channel was the smallest out of all 3 tested. The accubond had 93% weight retention and had the largest wound channel, But it did not penetrate as deep as the Swift. The Swift had 88% weight retention a smaller wound channel than the Accubond but a larger wound channel than the Barnes. Now for the rest of the story. I tried to go to 750 yds. the bullets are made difrently enough that the POI is enough that it would take a larger sheet of wood/ gelatin. Let me translate, MUCHO MONEY. I also tried the AMAX and the plywood ripped it apart, 2in of total penetration. I am going to redo the test next week with the Partition , Berger, and Cutting Edge bullets.
I have used both the Barnes tsx and the swift sciroccos but not the accubonds. Both 180gr pills from a 300rum. The sciroccos made an appox. 1" entrance with the lungs and heart non Existent with an exit in opposite side. Barnes would do the same thing internally but 1 out of the 2 deer bullet was recovered. I can't seem to find that bullet at the moment. I have shot many deer with the sciroccos and never had one take another step. The two deer I've shot with the Barnes made it all of 15-20 yards.
Here are a few 225gr Barnes tsx shot from a 338 win mag I've recovered from elk.
Left to right, 700 yds, 550 yds, 200 yds
All three were lung heart shots.
My dear boy if 5 miles away they don't sit up in their beds and ask what the HELL was that, the gun is not big enough!
I really wanted to like the sirocco II bullets, but my 7mm Rem Mag X-Bolt just don´t like them. Group Sizes go from 1.5"- 2¨@100yds. I switched to Hornady InterBond and shoot consistently 0.75¨- 1¨groups.
As far as internal damage, never shot a deer with the swift bullets, but Interbonds perform really nice. The last deer I shot ran about 25 yds but I can´t explain myself How in the world did that happened. There were pieces of lung and heart all over the spot where I shot him.
I'm about to start loading for my 257. I may need some of your expertise on it if you don't mind. I have some Bergers and Barnes. No accubonds.
I just polished and sized some brass so I will start soon. Interesting, I resized the brass and felt nothing in the press when sizing factory 1 time shot rounds. Is that normal??
ALS what powder you using?
