Following on from my .22 centre fire compared I started thinking again on showing how .243 bullets compare with each other as there was mention of the calibre on the thread. Again using max speed from the Nosler guide and all Nosler bullets ( in this case all their Balistic tip ) All max range keeping in 3 1/4" circle 55 grn @ 4069 fps 253 yards zero 293 yards max range FV 10mph 6.93" @ max range 70 grn @ 3630 fps 253 yards zero 268 yards max range FV 10mph 5.76" @ max range 80grn @ 3438 fps 233 yards zero 269 yards max range FV 10mph 5.43" @ max range 90 grain @ 3308 fps 217 yards zero 250 yards max range FV 10mph 4.93" @ max range 95 grain @ 3144 fps 207 yards zero 240 yards max range FV 10mph 4.43" @ max range As well as the ballistics shown one must also consider terminal performance, Deer weight bullets do often pencil on fox due to their thicker jackets and sturdier construction. However I have personally shot a great many deer and fox with the 95 grn btip above and found it to be uncommonly good at both, though they can over fragment at very high short range impacts with brain shots the results can be pretty gruesome. At reasonable ranges they are fine but then again shots of the type mentioned are not taken then. I have further been very impressed by 70 grn on fox only and a couple years back got into the 55's for their higher frangibility as a risk management measure ( not that I might take a shot with one I shouldn't with another). Previously ignoring them on grounds of faster barrel erosion and poorer wind performance. And yes the 55 grn 6mm beats the 22-250 5.56mm. with a bullet of equal weight. But it takes 22 grns more powder going down the tube to do it. Yep its like adding a case of .222 on top! More bang, harder moderation and shorter barrel life all for 0.83" of wind and 22 yards of max range. Personally I should run the 70 grain and gain a bit more wind again for the same max range as the 250 as makes no matter
