Versifier Thanks ; I could not hit a golf ball at 100yds let alone 400. I would have to see the ruddy thing first.Take your point about loading for accuracy above velocity.I found with the 375 The old nitro express stuff by H&H grouped better than the more modern loads.Also the 270 grain and the 300 grain had almost the same point of impact out to about 200yds.
I am loading 270 grain Hornady round nose s.p. for the bush and 300 grain SPBT for the more open work.Am near the same point of impact at 2700fpsfor 270gn and 2530 for the 300gn Which is not far from H&H original.

Dave, Did not see the primer over here!! could be in South America Or Antartica! As you know your Aussie Possums are eating us out of house and home over here,Well I had been Waiting for a stag on the bush edge one evening, the stag never turned up but a squalling pussum came grizzling down the track and I let drive with the 375 at about 25yds.We found a bit of skin and a couple of feet and a hole in the ground so I get a fair Idea where you are coming from.
Getting ammo is a real pain over this side of the alps and I will probably have to consider loading 300 Win Mag. These shells have a very short neck. Do you see aproblem with this. I have Norma brass and are considering using Lee neck sizing and factory crimp, collet dies.I would value your input on this one. The rifle is a Brno.We have a magpie problem over here they are cunning enough for me,the crows must be something else.I used to shoot Fallow in my mispent youth and really liked it .You are lucky to have a herd.
May the eye always be true good hunting Graham

Graham the .300win is a dear old friend of mine (as is the 375 H&H of which a Old 601 Bruno still haunts my safe) Don't let those short necks scare you with reloading for it ! Reloading really opens up the scope of the range of uses for the .300 !

ADI's AR 2213SC & AR2209 work well in the 300 Win mag & I love AR2209 in the 375 with AR2206H being ideal for reduced loads in both rounds ! The formula being
Take the max listed load for a bullet weight listed with AR2206H & multiply it by 60% & the result is the reduced load ! (great for cast bullets )

Go for the Lee Collet & FC dies. I have yet to see them fail to improve accuracy in ant chambering I have tried them with. Heavy loads in magnum cases have a reputation for stretching case webs and resulting short case life (head separations), some complaining of only two or three loadings. But again, like with the Swift, I believe loading down in the middle of the pressure curve will give you many more loadings, better accuracy, and longer barrel life.

Dave/Versifier,
Many thanks, I am using A.D.I. AR2209 in 375 and find results very uniform.Use78grn in300grn and 81.1 grn in 270 grn bullets.I figure using 180 grn bullets in the 300 and figure using AR2209 in this.Will save on having to use different powders. 180 grain may not be the ideal choice,but I figure it will shoot flat enough for the ranges I confine myself to.
Dave do you find much variation in different batch lots in A.D.I. Why I ask is I got a new lot and the supplier supplied match primers which upped the velocity 50ft/sec and very uniform. Not worried but wonder? Whether it be powder or primers.Latest news this am, Dept of conservation wants to wage unrestricted warfare on Canada geese,and is muttering about having no restrictions on shooting.In most places they can be hunted for 8 months of the year anyhow.They are also thinking of adding Plovers and Paradise Ducks to this in some areas. It seems Aeroplanes are scared of the Plovers. the mind boggles. Good Hunting And may the eye be tru Graham

I must admit I'm very pleased with the ADI lne up of Powders back when we had a sready supply of imported Powders I did'nt give Mulwex as they were known, much of a look in . Once I started using them though I 've found them to be very uniform from Batch to batch! Also they are very tempriture tolorent ! I can load up a batch in winter & use them in summer with no pressure differances ! I reckon the 180gn is a great choice for the 300 Win when you have a 375 lurking in the back of the safe .For heavier work ! I have always pondered the idea of a 300 & 375 H&H at the same time but it has yet to happen!

Versifier /Dave , thanks for advice. I have not been able to spot any sign of head separation, but am not sure how this would show . I have to trim a slight shaving off winchester cases at each reload but all other measurements seem Ok with a vernier, though I prefer feel with a light caliper. Still the brass has to come from somewhere. The book says to look for a shiny zone just forward of the belt ,this I have not seen yet.I wonder if the Lee collet crimp tends to cause this elongation which is very small. I am up to 10 reloads in some 375, should I toss these.Graham.

[versifier]

Graham, if you're getting ten reloads out of magnum cases, it seems to me that you are obviously not pushing the pressure. But I do have one question: you said you "trim a slight shaving" at each reload. Are the cases reaching and/or exceeding their maximum length (2.850" for the .375H&H), or are you just returning them to their "trim-to" length of 2.840" without having reached or exceeded the maximum? Conventional wisdom says to scrap the cases after five trimmings, but this assumes you are taking .01" or more off each time you trim, i.e. they really need trimming because they are getting difficult to chamber. The way you phrased it makes me wonder (but considering that if we were talking face to face we probably would barely understand each other's accents ), so I want to be sure I understand exactly what you meant.

The way I was taught to spot an incipient head separation is to take a 6-8" length of thin steel wire and put a right angle bend 1/4" from one end. Stick the bent end into the case and use the point to feel the inside surface of the case down near the head. If you feel a bump or groove on the inside of the case wall from thinning that is not obvious from the outside, toss the batch of cases. The .303 Brit case is famous for this, (that's how I learned about it), but magnum shooters also use it to make sure their cases are OK.

Hell I did'nt think anyone did that anymore ! I've mentined it to shooters over here & they look at you blankly ! I learnt the same way !

Dave / Versifier, I trim cases at 2.843 where the trimmer gauge is set. I checked the wire method and also cut one case down the middle. all is well So I figure if I keep to about 8 loads and check all cases with the wire that should be Ok.Would you agree with this. Any thing which feels suspicious I will cut and look.Most of the large capacity british cartridges are fairly mild in the pressure area is my understanding,and the 375 is in this bracket; the 300 will be something else and I have no intention of pushing any where near the limit. Dave; My son has a nice Westley Richards 303 built on a longtom action and proved for Mk7, I used it a lot in my youth. The S.M.L.E. was the standard issued to the cullers,and most of the real big tally men used this rifle exclusively in the early days.I guess if you look at it the 30 06 and the 303 would have accounted for more game than any other caliber.Many thanks for your help and may your hunting days be many and the shooting eye's true. graham
