There is a pretty good contingent of LR shooters shooting the Knight and BIB flat base bullets for 1000. I shoot the BIB 187 FB bullet in a 300 WSM
with 12 twist. Lot of guys are using the 300 Ack Imp and 12, 13 or even 14 twists with the 187 BIB and up around 3300 fps.
The major reason is that it is much easier for the custom bullet maker to make a very good FB bullet compared to the BT. We take the normal BT sort by weight, ogive and then some run them over a Juenke machine to sort further.
BIBs, I take them out of the box and shoot, they are that much better quality wise.
Now we give up a good bit of BC, but in a known distance game that is not an issue and quality bullets mean more.
The BIBs use a pressure ring on the base and that must be in the neck. That means the chamber must have an extra long throat and 210s will not even come close to touching in my chamber and it makes it a one bullet gun.
Bottom line is that for LR hunting, you will want the BT normally due to the extra BC.
