I took my first deer with a .270, a Churchill with a Pecar 'scope on detachable side-mounts, in 1992. It had a twenty-two inch barrel and I was using Winchester Silvertips. I got rid of it very soon thereafter. The muzzle blast was most unpleasant.
Prejudice against it is that it is probably better here in the UK with a 140 or 150 grain bullet as against the original loading of a 130 grain bullet with it as a "Western hunting" rifle. Our hunting here in the UK, even in Scotland, is more typically "Eastern hunting" as they'd call it in the USA. And even there the 270 with its 130 grain bullet is thought less than the 100% ideal, or so I believe, as it is too fast for the shorter distances involved.
Other prejudice is just that it is a competent but, now eighty-eight years after its design, considered "old school" or more likely "old hat"! But when it debuted at 3,110 fps it was considered astonishing for its day and very much a wonder by many who had started their hunting career with blackpowder cartidges averaging 1800 fps!
Bottom line it is suitable and more than adequate for ANY lawful quarry here in the UK. It always has been and always will be. Prejudice against it is mostly based on its performance in shot out hackneyed rifles and from meat damage form the use of badly placed shots with unsuitable bullet and velocity combinations such as Winchester's 130 grain Silvertip at ranges of one hundred to one hundred and fifty yards.
