Slight disappointment with Remington

[Guymullins]

I am doing an unseasonal hunt next week. Some Blue Wildebeest are being offered at a good price and I need to take youngest son on his first hunt.
My .375 H&H Remington heavy barrel Model 700 has served me superbly for almost thirty years. It is a Remington Custom Shop product and began shooting badly during my last hunt a few months ago. Aiming at the heart, I shot a Black Wildebeest in the neck at just over 200 yds. The next animal, a Blesbuck, was shot through the upper front leg, twice at 170 yds. The rifle (or the rifleman) was shooting quite badly on the range prior to the hunt. I put it down to the cold and high winds.
Anyway, once home, I went back to the range and shot some paper to see whether it was me or the rifle. At 100 yds, it was grouping all over the place. About a 4 inch group at 100 yds, where previously, it would comfortably group under an inch at that range.
First stop was the scope and its mounts. I have a quick release scope mount for swift transition to open sights for dangerous game.
The scope and mounts seemed firm, so I took the rifle to my local gunsmith telling him I had checked the scope, mounts and anchor screws into the stock.
I went back to check progress yesterday (I want to do some range work after any alterations he may have made). He tells me that the rifle had never been bedded, and that the action was now eating into the woodwork. He was bedding it and it will be ready tomorrow.
Now, my disappointment (slight) with Remington is: One would expect a rifle from the custom shop would be bedded. Especially one of medium calibre that could shake itself out of true quite easily.
I can't complain about its initial accuracy, but this is a poor show and in my eyes , unworthy of one of the worlds best and most accurate rifles.
