I had the same experience with an '06 I bought for my middle son. I think the higher intensity rounds are less forgiving when it comes to barrel gap & latch engagement, so at least some truth to what you are saying. Later, I bought a 280 that was a tackdriver. It had a very tight gap (.0015) & good latch engagement. But it is not a big deal to me & not worth arguing about, I like them for 45-70,
45-90 type rounds & muzzleloaders. They are usually good in 223, but the forearm is sensitive to bipods & such & I am done with them for all but the above stated purpose.
