It usually pays to work up a load in a different rifle. I personally wouldnt try handloads that blew a rifle up in a different rifle

For safety and accuracy determination.

my old rifle had loose bore and longthroat...so loads had plenty of room to releave pressure before projectile enguaged rifling.....my reloads for it were at hot end of scale.....
also I partial length resized...so in effect the shoulder COULDVE been up to ????1mm longer than normal......
IF new rifle has tight chamber,they wouldnt fit in.....the case would be too long......and if short throated,a hot load could well become a bomb...nowhere for pressure to go....shorter throat=shorter pressure curve=lower pressure tolerance=lighter loading.......
if you take it to the extreme,look at how Roy Weatherby made his rifles chambers....big long lead into rifling so when primer goes off and powder starts to ignite the projectile starts moving forwards,in effect giving a bigger case...this I believe is the theory behing Remington Hypersonic shot shell loads too....1700fps Vs 1500 in others.
my good mate just around corner also owns a .270 the loads his rifle tolerates are 2-3grns BELOW book maximum before he starts getting pressure signs...my old girl was 2-3 ABOVE .
hope that makes sense.

Death or injuries ,from reloading is there many horror stories myself personally one sticky bolt said round went through washing machine should of chucked it but my Scottish ancestry is to thick Win 760 powder Some South Westland drift wood sorted it .

Sound thinking Micky,
My experience has been that current production rifles have tighter chambers compared with those of 30 plus years ago especially in sporting cartridges. One .308 I worked with chambered some factory loads tight. Your partially sized cases would be very unlikely to chamber in the new rifle. This is quite apart from the load likely being too hot. 30 years of use likely provided the long throat and reduced pressure. Something I would be interested to know is the make and model of both your old rifle and the replacement. Just curious.

Well who has eaten a bolt ,so where are the stories

Your approach here to others' safety is irresponsible.

You don't need to wear a bolt as could happen in the most extreme case but a buggered rifle (recently documented) or a lost eye due to a shower of crap coming back thru some of the poorer gas handling bolts should be enough incentive to take care.

Well said Zimmer,
Additional to the case you mentioned two local cases that I know of, although not first hand, resulted in two buggered rifles and two injured shooters, one with damaged sight. I suspect that Micky has been extremely lucky hence my interest in his rifle above. In a rifle with poorer gas handling his outcome could have been quite different. Micky is to be commended for sharing his misfortune with us so that we too may learn from it. Not everyone is that honest.

There was a guy down Murchison or Buller in the last six months or so.

I meet a man wallaby shooting who had a mean scar on his mouth through to cheek caused by a bolt .But it was caused by a gunsmiths error .

Greetings Micky,
From your description it sounded as if your rifle was one with a recessed bolt face as is your Howa replacement. They handle the gas from a ruptured case much better and probably saved you from injury. I am sure that your .270 Mk2 will grow on you over time. Some faced with the need to replace a favourite hunting rifle would plump for a newer, flashier or just different cartridge. Please note the lack of the word better. Well done on sticking with what you know to work. Your training as a curmudgeon is coming along nicely.
Regards Grandpamac.
