One of the raging debates for hunters is what maker/type of bullet for your particular hunting cartridge. Some people want the baddest, fastest, newest, most sophisticated bullet on the market --which also tends to be the most expensive. Winchester Failsafe, Nosler, Barnes, Hornady super-duper bullets with 100% weight retention and nuclear tips (not really) seem to be "must haves" to take down a deer or an elk.
Seems to me, that people were taking these animals for hundreds of years with round lead balls, minie balls, round nose lead bullets, and fmj's without too many problems. Now, I agree, if you are a hunter, you should use the right bullet to humanely put the animal down and FMJ bullets are not the bullet construction of choice. But my question is, do deer really know the difference or drop any faster with a Winchester Failsafe over a 40 year old Remington CoreLokt? I don't think so.
Bullets with a higher sectional density, explosive tip, hollow points, and fragmented bullets all have their place, but do you really need to spend $35 on a box of 20 rounds to take a deer or turkey when the $14 ones will do the job just fine? Marketing at it's best... you must have the newest model to be any good.
