I ordered some to try out in my 6.5-300 Weatherby Magnum. Might get them around 3600+ FPS. I am pretty sure on deer this will jelly the lungs on them.

No announcement yet.
Anyone use the Hornady 129 grain SST bullet in 6.5?

I have had SST's blow up inside two deer that were shot at 100 yds. Neither bullet exited the body and both deer were difficult to find since they did not bleed until they ran 60 yds into thick cover and fell over dead. This was with a 308, I would think it would be much more likely to happen with your gun at that high of velocity. I think a bonded bullet may be a much better choice.

No doubt whatever animal you hit will die from hydrostatic shock. You need to be careful on shot placement as the bullet may "splash" due to velocity, RPM's, and bullet construction
I'm thinking a 140 gr bullet at reduced speeds (3400 fps ???) will provide better bullet results.
Before pushing maximum speed, find the barrel anode and shoot for optimum accuracy. Just my opinion as I shoot lots of cartridges that exceed 4000 fpsLast edited by Cajun Blake; 07-16-2017, 04:57 PM.

Originally posted by Balcones_Walker View PostI have been disappointed with 129 SSTs' performance in the 6.5 Creedmoor: they tend to explode. It seems like they're designed to make marginal shots lethal but for clean shots they ruin a lot of meat. I like Barnes TTSX much better and am starting to reload them for the Creedmoor now.
I hit 3 does in the lungs with them (ribs in and out) and watched the deer bed up and take an hour to die. Impact velocity was about 2500fps shooting 120gr from a grendel.
Low impact velocities I have gone back to the NBT. Higher I have gone to Berger.

By the way I just noticed we *are* talking about apples and oranges - your grendel is hitting for 30% less energy at 100 yds than creedmoor. Better expansion makes sense in that cartridge.Last edited by Balcones_Walker; 07-17-2017, 01:39 PM.

Bergers blow up like a hand grenade inside the chest and if anything exits it will only be the lead core. In my .308 with 168gr 4-6" shredded holes. In the .300 RUM more like 8-10" with 210gr.
Deer have all been DRT.
After collecting enough data I have found that if there is enough damage on the inside exit wounds are never needed.
