Gday Kevin
So TSX in 500J and 470 Nitro is good for buffalo?
It works but definitely better bullets but the issue is not when they work it’s when they don’t that’s the concern for me & where I come from
this post of
@Altitude sickness is one that needs to be understood before a blanket statement of the Barnes are going to work consistently or any bullet so please take that into account for the next part
So it makes complete sense that with any bullet design, they need to make impact 100% nose first. with zero yaw
This is the part that we can hone in on to see why /where
Number 1 is easy & explained well here
So of course a bullet not hitting perfectly straight due to the wrong rate of twist or spin rate will impact expansion.
But I also ask who actually determines the requirements of the twist required to open the bullet & getting a little deeper the amount of rpm
Even more important is what level do they use to call it good & equally important what test media are they using to determine this ????
Yes that is a very important part to understand if one is after consistency!!!
Which the company is ultimately setting those minimum limits so should be fine right hmmm
No as we can see even in this thread yet people look @ the good & dismiss the bad & with respect Kevin you have not done enough homework with your response in post number 146 & why I offer some advice based off actual field results & only recently various media tests
Before those are explained a little more we better take number 2 into the equation & once again this is explained well here
Also as the bullet slows enough it starts to wobble it’s not going to open correctly.
But also it’s not only when the bullet slows its also when it leaves the muzzle & takes a little time to settle & a general rule I’ve seen put out is 20/22 yards plus & can confirm that you get more issues with bullets terminally @ less than 15 yard impacts in bovines than 25 plus ( velocity is not the issue here as we thought that was the case & it’s better linked to wobble imo as results showed a pattern of the range being the issue not the velocity impact)
Number 3 is what makes the bullet itself expand
A is it a hydraulic activated system or
B a mechanical activated system
Some bullets even use both
These are also very important to understand if one wants consistency as if one is using a hydraulic activated system one needs a hydraulic substance entering into the hp cavity which is fine right as a body is around 80% water ??
Yep if it hits the critter on most shots but what about a dry mud encrusted critter of a skinnier than normal critter that has very little meat between the hide & bone or a knuckle shot that on some critters some angles basically no fluid on those shots so the chances of failure have increased substantially
So back to the company & the ones that use ballistic gel give pretty consistent results but as has been shown from testing Barnes by vortex they just couldn’t get a pill to open @ range ( I’ll see if I can find the video & link it if you want ?? Please confirm if you do or don’t as I’m very time poor ) & wasn’t until they put a think it was a snap lock bag of water in front of the gel that the bullet actually worked that’s ballistic gel that still needed help to get the bullet to work hopefully that gives a little insight .
The worst companies to listen to are the ones that use milk jugs full of water as their test media hence parameters they tell us are good to go as this just masks the real life results & what occurs in critters is different on a way higher level again & the pattern of a needing hydraulic medium type A bullet to work ( Barnes don’t use milk jugs so tick on that )
The mechanical B type bullets don’t require hydraulic to work & another day on those id suggest is better left to then imo
There are other factors ( numbers if one likes as I only showed 3 ) that go into this & ultimately finding which bullets offer better consistency over the other & that is one personally having used the Barnes in the Jeffery on many critters it’s one I don’t use them anymore as I can’t rely on them to give consistency & a 500 Jeffery shouldn’t be a problem creator it should be a problem solver !!!
Here’s a few pics
Also have some recent wounds from elephant that are also interesting but I’m yet to put all that stuff together
So my advice is please just do a little more research & hope the above helps
Although you maybe happy staying with the Barnes which is cool if one wants just as long as we don’t paint them in a all being ready to go light as they are not for the .510 cal even though they work well when they do it’s the bad that concerns me & why I offered the above
Cheers
