6.8 mm Hornady 110 gr OTM, vel=2613 fps from a 16” 1/11
BG: pen=17.7”, NL=3.5cm, Max TC [email protected] from 3.5-20cm, RD=0.50”, RL=0.37", RW=80.0gr
Glass: pen=14.0", NL=0.5cm, Max TC [email protected] from 0.5-24cm, RD=0.32", RL=0.51", RW=74.5gr

6.8 mm SSA 115 gr OTM (SMK), vel= 2520 fps from a 16" 1/11
BG: pen=15.0”, NL=5cm, MAX TC [email protected] from 5-28cm, RD=0.49”, RL=0.26", RW=53.5gr
Glass: pen=12.8", NL=0.5cm, Max TC [email protected] from 0.5-19cm; RD=0.48", RL=0.20", RW=32.7gr

While both the Hornady 110 gr OTM and SSA 115 gr SMK OTM offer acceptable terminal performance, the Hornady projectile is more consistent.

In addition, since we had a bit of gel left over, single shots of the following loads were made:

6.8 mm Remington 115 gr FMJ, vel=2436 fps from a 16" 1/11
BG: pen=15"+, NL=7cm, Max TC [email protected] from 7-32cm, RD=0.40x0.15” (bullet flattened), RL=1.09”, RW=96.3gr


6.8 mm Hornady 110 gr VMAX PT, vel=2522 fps from a 16" 1/11
BG: 13.8", NL=0.5cm, Max [email protected] from 0.5-20cm; RD=0.54”, RL=0.22”, RW=55.5gr


6.8 mm Speer 90 gr TNT JHP, vel=2610 fps from a 16" 1/11
BG: 13.8"+, NL=4.5cm, Max [email protected] from 4.5-24cm; RD=NR, RL=NR, RW=NR

Nice gel test about the performance of 6.8 SPC. What was the load in last photo that said 6.8mm 101 grain penetrator? Was that the Silver state armory steel core or tungsten core Armor piercing 6.8 SPC ammo?

I don't know who loaded that up.

I would like to see a picture of the 90 gr TNT in gelatin. I just bought 600 rds of SSA.

I know just buying the bullets would have been cheaper but I wanted the brass too.

I thought I had one up. It is similar to the Sierra 115 GR SMK.

We are loading the 90 grain TNT at 2,900 FPS from a 16" barrel. Some 16" barrels drops the velocity down to 2,840 and others will run the same load at 2,940 FPS.

Thanks, it is possible that I just didn't see it Paulo, as I have trouble differentiating some of the load data from the photos. I find some easy to follow and some not so easy.

I am looking forward to shooting it out of a 20" SAM-R. I bet that smaller critters will become red mist when hit at those velocities.

Second from the bottom.

Are your sure? It IS confusing trying to figure out what pic goes with what bullet. The very bottom pic is obvious...the metal barrier test, but...


If you right click on the pics and look at the file name....

The next pic up says it is the 110gr VMAX

the one above that is the 115 gr FMJ

I dont see the 90 gr TNT....
