At the time I worked this up there was pretty much nothing 6.5 avalable.....now I dont really need it.
But I'll stoke them up and see how they go for giggles and shits.

153atip Hornady brass 56gr RL26 215 primer COAL .30065" 2985fps from 22"

It certainly does up close(less than 300y) I haven't had to test it's long range terminal effects yet but the atip appears to penitrate a bit then open up....more like a Berger or Targex than a Amax or Eldm.
I hope they work at longer ranges....my googling suggests that they do.
Have shot steel out to a K which is about as far as I can go with single turn turret and stacked a nice group consistent with data.
I'm pushing them out of a 7 twist so the extra rpm may help expansion or not....

OK interesting, saw a few packs of the 153 for sale today but just grabbed another 147 pack, half the price is the kicker...

I hope the bergers shoot well, if they do I will need to track down another pack or two.

I only have 2217 as a suitable powder, if I can get 2900 I will be happy... but maybe only 2850.

Can Get superperformance but reviews are variable in terms of stability

My barrel will be 1:8 which should be plenty and might avoid the rumors of projectiles blowing up mid flight

Yeah while certainly more twist is going to increase the risk I wonder how much of it is actually due to roughened firecracked throats?

2217 should be good.

If you did it again would you stick with a 22" barrel?

How many rounds have you launched? Would be interesting to scope the barrel

I'd either go longer and no suppressor or 20" suppressed and probably a 8 or 7.5 twist...... unless some heavier bullets come out
I'd have to have a count up but at around 350 down the tube and throat still looks good but I don't thrash it on gongs either.

yeah yeah...you fellas and your flash Harry new ideas......... the older cartridges have had a new lease of life with new powders and more sleak projectiles....and different twist rate barrels....but some times the old ones just are pretty darn good too.... the 7mm-06 in its true .277 form isnt to be sneazed at and there are plenty of other close cousins.....find it funny as heck the .280AI gets rave reviews yet no one does the AI to the .277 version cause its good enough already LOL.....ducking head now waiting for all the jandles an gumboots to fly!!!

Good to hear they work in close . I’m sure they will go fine out far. I agree fire cracked/rough bores and throats not just speed and twist . Example 28nosler good for the first few 100 fast twist fast velocity starts blowing up with 300 down the tube …. 180 eldm

That's when you change to hammer or cutting edge etc

I think we are reaching the point in heavy for cal 6.5 and 7mm that for the bigger magnums going to a gain twist or monolithic super heavys might be the only real solution.

Shot 2 deer this morning with the PRC, 140amax!

It’s hard to go past the old 140’s aye. I have a few left but I’ve been using 143 Eldx exclusively as a good c loads for me.

Even at 5 metres they smash through even large animals: @2820 fps.

@Vietnamcam & co how do those 147’s go up close at said Prc velocity’s?

I haven't used the 147 eldm just the 153Atip, they go fine up close.As above they seem to penitrate a bit then open up more like a Berger or Targex.

Yes they do! I have a box and a half left of the Amaxs then I’ll have to load something else, if anyone has some they don’t want…..

The 140eldm should behave the same mate

I’m sure they will but then I can only say they have been shot not AMAXED
