Is everybody breaking in their 6.5-300 with the Barnes 127 factory load? I did that with the early Accumark I sold. I did do the recommended brake in ( for once) and was getting sub moa groups. Even Barnes says don't use their bullets for break in, but they were all that was available! Sorry if it is FUBAR, PARA45!
I’m leaning towards the 257. Problem is I can’t use that in PA for elk hunting. We have a caliber restriction of 27cal with 130grain minimum. I hate to lay out the money for a 257 and not be able to use it.
I have watched the long range shows and it got me to thinking about bullet performance
I did some figuring; going by velocity of bullet, and energy at impact.
I shoot barnes bullets and test the Hornady ELD-X. Barnes lists their bullet to expand down to 2000 fps, l think Hornady is 1800 fps
I never push the limit when shooting at game, also l want at least 1500 ft lbs of energy.
I shoot a .257 wby, 100 TTSX, 340 wby, 225 TTSX
Going by the above listings the:
.257 wby = 450 yards max
340 wby = 500 yards max
Some may question this and that's fine but
I shot a bull elk at 380 yards with a 338 win mag and a 225 TTSX, the bullet weighed up at 226 grains, there is a piece of bone under one of the pedals. The point is this was max range for this rifle bullet combo, to get reliable expansion with that bullet
So a 1000 yard shot on game, with what bullet?
Also do a little research on 1000 yard F class winning targets, you may be surprised on the size of the groups.
It's not a matter of weather you can hit an animal or not, its weather you can take it cleanly with one shot.
I have proven this fact to myself recently and will "never" push the limits of a caliber again.
340
Well he must be mistaken or don't know what he is talking about because my MarkV ULW has 6 lands and grooves and no I DID NOT miscount and I marked every one and counted 4 times. So apparently it is just the Vanguards. Mybe someone else with newer MarkV can check theirs.My early order Accumark is the came as yours.
You will more than likely have fantastic results with those bullets. I have used BERGER’s for 15 years in my .257,115g @3500 fps and .300, 210g at 2940 fps. I have yet to have a failure. I would be using them in my 6.5x300 but the 143 eldx’s had a little better accuracy. Don’t shoot the shoulder and you won’t waste any meat.
.257,115gr. @3500 fps? Pretty hot load, about 200fps over max in the Berger book from a 26" barrel!
