For this discussion, I am using as an example. 45 colt, 250gr XTP, or 300gr XTP.
Only difference in bullet is 50grs. Using a Heavy 30k loading.
Following Hornady’s loading manual...
Theoretically speaking...
On the 250gr XTP you can achieve about 1350fps max. (My chrono 1368fps average)
On the 300gr XTP you can achieve about 1300fps max. (My chrono 1305fps average)
Albeit to achieve those maximums, each is using a different powder. Obviously the gun used makes a difference. But with all things being equal...
If your hitting your target, let’s assume animal for hunting or SD, in the exact same spot on the animal.
Which is more important? Bullet weight or speed?
Obviously in this example the difference in weight is only 50grs, and a difference of 50fps. So might not be big enough difference to make a difference. But then if this is the case, why have a 250gr and 300gr version of the same bullet?
If I am hitting the animal in the same kill spot. Both will make the kill so why use one over the other?
I have actually loaded and fired both. Felt recoil I couldn’t tell the difference between the two. Accuracy difference was negligible and unnoticeable to me. Cost was the same other then the cost of powder. average Chrono speed on both was faster then published, but then they were fired out of SBR Henry mares leg (13”)
When I fired into Clear Ballistics 10% gel. Average depth was basically the same. 1/4” to half inch difference at most. Expansion, very minor differences.
