I do a little reloading and I had a guy ask me about his 270. He said he is using a 130 grain bullet but in his thought process, the bullet is going too fast to have any expansion on the deer. So he was wondering if switching to 165 grain boat tail mould be a better bullet to use. I realize this is a fairly vague question and there are some missing variables, but any oppinions are welcome.
Do they make a 165 grainer in .277?--maybe in some of the boutique bullets there are 170 grainer available. I think Winchester made a 170 grain in factory ammo, but if I remember right the price was kinda' breathtaking......The heaviest of the readily available bullets I'm aware of is the 160gr.
And no, no bullet goes too fast to evade expansion--most bullets start expanding as soon as they hit hair--or shortly thereafter.......
Indeed, it can be quite the opposite, lighter bullets can open up too much to acheive sufficient expansion. Just because a bullet goes in one side and out the other doesn't necessarily suggest lack of expansion, but rather good penetration.
If you buddy wants good expansion with very good penetration at hair burning range to waaay out there, try a Nosler Partition in 150gr, or 140gr, or 130gr.......
