Thanks for the PM and re-post here regarding my response.
I wasn't' positive where this .375 H&H thread was... lol - now I'm on the right page and following along.
In your original post I believe it was this one: (My comments are in blue.)
"Use: Mostly trying to make little tiny groups on paper so when I get out hunting I'll have confidence in my rifle, my ability to hit with it, and a rapid second shot if needed. I agree... practicing and realizing the potential capability of shooter/rifle/load combo is fun, additionally building self-confidence using your preferred equipment.
My questions for people that have owned a Howa rifle in 375 Ruger, or have fired one: The hottest Howa I've had experiences with are .300 WIN, .300 WBY, & .338 WIN mags. No .375 H&H Howa trigger-time at present, and I have not seen one on the range.
#1: Accuracy: What should I expect, what is common? Howa accuracy tends to be better than average... in the ballpark of <2" with just about anything you feed 'em. Most I've fired were honest 1.5" guns with good factory hunting ammunition. A few hovered near 3/4" 3-shot groups. When I say 'better than average - I mean all guns preformed right about the same. I'd wager a select new manufactured gun with best load should hit <1/2" at 100 yds.
#2: Is this a quality rifle? I do feel that Howa 1500 is a rifle of pretty darned consistent factory quality and reliability... Japanese manufacturing with attention to detail seems to be there throughout the years - no matter who's name was stamped on the receiver. Keep in mind a few a few safety precautions, issues, and upgrades over the years - same with many manufacturers.
#3: Any known problems with it? More or less - I'd say the answer is no. Some triggers tend to be a bit rough, maybe slow, not quite crisp in fire controls... if that makes sense!
#4: Do you recommend for it, or against it? I'm fairly certain it would put you in the breakfast club of Tikka-fried-over-Weatherby w/ sides of Ruger-RemChester & lightly Browning-Savage
#5: What should I have asked about this rifle that I failed to ask? What other rifles or barreled actions are available in this price-range? The Answer is SAVAGE 'Alaska-Giude' if going stainless/synthetic, but would not be my first choice. Used guns may be a better option. The Zastava Yugo Mauser can be had from a bunch of import names over the years. However, many are not true .375 H&H receivers... you'll find a finger-tip cut in the top, forward end of the receiver to accommodate the bullet tips. It works, but I do not recommend the kind of short-cutting.
#6: How does it measure up to other brands under $1000.00? Safe to say it likely measures up well - unless you find something more desirable used.
As for the stock...If it's lousy then I know that HS Precision or another stock manufacturer can probably fit the Howa. I'm not opposed to replacing the stock."
I think people make much too big a deal about stocks. I've fired many dozens of fine shooters with less than the best fits or pretty furniture.
An additional comment:
By nature the .375 H&H with 300 grain loading will rarely be picky... this is the only grain I use for everything.
