The great 260 bullet weight debate

[ICANHITHIMMAN]

Ok lets say you have a 260 rem with a 27" 1-8 twist barrel and wayetts box mag.

Now you want to shoot the JLK 6.5mm bullet do you pick the 140g bullet with the BC of .630 or the 130g bullet with the BC of .620??

You could get a littel more speed if you went with the 130g over the 140g but is it worth the loss of energy at lets say 1000 yds?

Depends if those BCs are actually correct

Probably the 130 but I haven't run the numbers.

hay thanks for the link its a little vexing at first but I will work through it. They are the BC listed on the JLK site by Swampy.

OKAY- what do you want to shoot at, targets or critters? Since the BC's are so close, they are going to buck the wind pretty closely.
Now since the 130 is going to outperform in velocity, it's going to have a flatter trajectory. You start getting out too 1000+ yards the 140's BC advantage and weight will take over and it will start to outshoot the 130, IMOP that is.

highdrum thats a good opnion I like it well said its for critters of course. My first choice was the 140 and still is but the 130 is so close BC wise I just got excited over the slight edge in veloicty.

With bullets that similar, I would use the one my rifle liked best at the velocity it liked best.

Dont complicate the matter, let the rifle speak. You just have to listen.
