After very recently receiving my new Hankins SPML-45 and being extremely impressed with the initial three-shot groups using 275 gn Parker Match Hunters; what are the reasons and benefits/ detriments of shooting a heavier bullet? Is it simply heavier bullets produce less wind drift for long range shots?

I only shoot the 275s, I like to keep it dumb-proof. The heavier bullets have a higher BC (ballistic coefficient) so yes they fight the wind better for the longer shots. Dialing up for drop is easier than correcting for wind drift. I really don't think over 300 yards you will notice much of a difference. For hunting the heavier bullets hit harder, but you are already shooting an elephant gun, so do you need anymore energy. That is just my opinion.

when the weight goes up so does the BC of the bullet, yes less wind drift and less energy loss at extreme range but to go along with the heavier bullet is added recoil. usually as bullet weight goes up in a given design the bullet becomes less fragile because of the added mass on the rear of the bullet. its a trade off really, one must decide what your goals are, extreme distance in high wind? shooting as flat as possible over a given range? barrel twist comes into play as well, for the most part a 20-24 twist will shoot most bullets we desire to shoot but bullets over 325 grn might benefit from an 18 twist barrel? For whitetails we are way overkill with these monsters we shoot but one must decide what the goal is and let your gun be your guide as to what it will let you get by with. sometimes the ole shoulder will be the deciding factor  , other times it will simply shoot one weight better than another? |

Good answers you got there... All you need to do is try some different bullet weights and see what kind of accuracy you get... Just remember to lower your powder charge every time you go up in weight.

Hadn't read that in a while. Very nice data. I'm sure Kyle's bullets will do the same. |

Thanks guys, as always, good information. I am certainly not interested in higher recoil and and have no need for greater bullet impact energy. And to try heavier bullet weights to learn if they shoot any more accurately in my rifle is sort of pointless when the gun already has shot several almost one-hole groups using the 275 BE's and MH's. And thanks Jeff for the safety reminder about reducing the powder charge if I shoot heavier bullets.
I think I'll stick with the 275's and continue to learn how to shoot the rifle as well as I'm able.

Good choice.. It's easier to learn one good load than it is to learn three ok loads..
