I've shot my 375 RUger with 260NAB and 250gr TTSX bullets to 400 yards. Accuracy was good, and I dont' see any reason why I wouldn't shoot an animal at 400 yards. H&H should do the same.

I won't get in a pissin contest with you JWP but I have been shooting/loading the 300 H&H for many years and I suggest to you that if most of the manuals quote about 2950, some more,some a tad less, and all at 52,200 CUP or less, and all with 24 inch barrels, and they quote a working max for a 300 H&H not to exceed 54,000 CUP, surely you can understand that 3000 is easily doable for goodness sakes with 2 inches more barrel, an old and better powder, and apparantly with some modern powders, and btw I have an extra 1800 cup to use up if the manulas are correct. I think 12 to 14 reloads is a pretty good indication of a relitively mild and by mild I mean safe load.

It would seem to me than any rational thinking persom would be able to compute that as a doable option, if one considers all the FACTS, and if one is not just being confrontational.

I never said that you didn't get 3000 FPS. I said that you sure as hell ain't getting it at "MILD" pressures and that is what you claimed in your previous post and I stand by that statement.

This is what Hogdon lists for a 200 grain bullet in the 300 H&H


200 GR. SIE HPBT Hodgdon H4831 .308" 3.655" 67.0 2737 72.0 2932
200 GR. SIE HPBT Hodgdon H4350 .308" 3.655" 62.0 2747 66.0 2909
200 GR. SIE HPBT Hodgdon H414 .308" 3.655" 52.0 2423 56.0 2649

Depending on the powder the amount is from 56 grains of H-414 to as much as 72 grains of H-4831. If yiu are getting 3000 FPS with a 200 grain bullet you are certainly at the top end of pressures

It appears that you have pretty much proven what Ray was saying. Since Hodgon does not list the test rifle nor the pressures obtained it is very hard to say for sure. In reviewing all the loading data listed for the 300 H&H, pressures are held to around 54000 lbs. Which is low for most cartridges. If pressures are boosted to the normal 62500 lbs, good brass and assuming the 26 in barrels that Winchester Model 70 used for the 300 H&H, 3000fps is very possiable. Might even try some of the other slower powders that Hodgdon doesn't list.

That's 54,000 CUP not PSI different measurements. 54,000 CUPs's is top end pressure

No I did not prove what Ray is saying. One more time Ray stated 3000 FPS at "MILD PRESSURE"

According to Hogdon date even the 300 Weatherby doesn't get 3000 FPS with 200 grain bullets

NOtice that the 300 Wea. hold more powder than the 300 H&H
3000 FPS is not possiable at MILD PRESSURES

I have used a 375 or 375 improved as my elk rifle since 1982. Ruger #1 as saddle gun for a few years and replaced that with a pre 64 chambered for Bill Steigers improved ctg.

Even with a 300 grain at 2800 fps you can still shoot it prone. (10 pounds with scope, sling and ammo).

You do not need a special bullet in 375 for ranges being discussed. Just practice. It is really no different than a 30-06 with match ammo.

Muzzle velocity is more important than ballistic coeeficient out to 500 yards.

With todays bullets I would recommend a 250 or 270 grain North Fork. There are so many good 375 projectiles nowdays.

With the improved you can step up to the 300 grain Swift, Woodleigh or Kodiak, but Id still probably use a 270 grain North Fork.

I have a lifetime supply of 275 and 300 grain Bitterroots or that is what Id be using.

Dont forget to have fun. Go shooting today!

JWP,
Perhaps your right, but if I get 12 to 14 loadings and that is only with the old surplus 4831 powder that is hard to come by these days and its the stuff O'conner got awesome velocity with his .270 at like pressure of other powders according to him, and I only have to trim those torpedoes 4 to sometimes 6 times, and inasmuch as I have shot the 300 H&H with enough powders and bullets to believe that I am getting pressure in the 50,000 to 53,000 CUP, but I will give you the benefit of the doubt, perhaps they are not mild as I think. I do not have the pressure testing equipment that the load companies do, all I can go by is cross reference and compare to other tried loads and compare to the loading Manuals. I have and that is quite a number of manuals..I mic cases and my loads are good there, with acceptable movement,and less than my .270 or 300 Win mag, and less than any of the new magnum factory loads such as the 7 STW, 30 RUMs, and the Wbys..My primers seem to be Ok, and bolt lift is 2 grs. below almost sticky. This is all I have to go by. It has always worked for me for and I have yet to blow up a rifle or even stick a round in the chamber on a bolt action rifle..

Perhaps your meaning of mild and mine are not the same..I believe mild is most max listed loads in the loading manuals btw..I know those guys are scared to death of law suits and most books max is about 2 grs. below true max. which is fine and that is where I losd most calibers, that being book max..Those loads work in Africa and all over the world and I have never had one fail..Therein may be our difference in opinnion. That said I have seen book max listed loads that were too hot in some rifles, so one has to approach these things carefully and I do that. With the old surplus 4831 I had to figure that one out myself, and its considerably milder in pressure than the new 4831, including the short core or even MRP or H1000..

That is according to O'Conner,since he had not pressure tested those loads he was only guessing. Yes I have shot O'Conner's loads and I do not kid myself - they are hot. That is shown by the speeds. I have spent enough time with pressure testing equipment to know that high velocity comes with high pressure.

"MILD" is starting loads not top end loads

Well, I'm comfortable with the loads I am using, mild or not, and as have been using them for years I will continue to do so but if a gun blows up I'll call you on the phone and say, "JWP you were right", so you can quit pressure testing.
