Improving bolt lift DIY

Anyone else have any luck with trimming 1.5 coils of the firing pin spring. Will this work ok with mil primers?

in all my ignorance, I'm not a fan of cutting coils on any OEM spring, even more if I don't have buyed first some OEM replacement springs _
it would be better, on my book, find and try first some spring with slightly thinner coils , but of the same overall lenght, if available _
about my 700, I've mounted a Tubb spring as soon as possible, but maybe am me..._
