Case sizing issues? Or is something completely shagged?

[fortune]

I'm sorry, I may be wrong but the level of inaccuracy you have suggested cannot (in my view) be explained by your die problems.

Its more likely a coincidence of a banged scope and poor ammo. Re zero with factory and try a few home cooked ones after.

 

Full length re-sizing takes a bit of force but not neck sizing - I once badly set a lee die and used force and destroyed the die's threading - stick a brazil nut in your press and see how little force it takes on the handle to crush it.

 

I had similar problem and above was fault. I used factory loads at 25 paces and they were all over the place. Caused by bow spring inside of tube that allowed the centre lens tube to move and the point of aim to shift in relation to the crosshairs. target picture looked correct every time but impact point had moved every shot. If you can, put a few of your reloads through another rifle to test them.

I am not sure if I am reading this incorrectly but a lot of the above is pointing to Full Length sizing being more accurate than Neck sizing.

 

Not going to get into a contest but that is just plain wrong.

 

That aside if you need to use that much force to neck size on a collet die then you either do not have enough lube or something is set up wrong

By definition neck sizing takes less force than FL sizing.

 

you can not adjust neck tension in a collet die, no matter how big and strong you are.

You are clamping brass onto steel

if you want to adjust neck tension either get a different press or polish your collet die mandrel

 

have you cleaned the inside of the die?

crud and lube build up can make you think the brass is hard

but 7 times fired brass could be rock hard by now, especially if it is hard brass to begin with, what brand?. get it annealed, it will cost you a tenner and they will come back better anyway. (I have 5-10x fired norma brass that works just fine without ever being annealled, but then I dont FL size and loads are reasonable not rocket burners)

 

read this and check all it points to.

Neck sizing correctly or full length sizing correctly and there is no difference in accuraccy. That said if you shoot competitively in any situation were its preffereable to get your a group off sharpish in a given wind condition the FL sizing makes good sence and it fair to say the majority play it this way at 1000 BR etc. when its harder to read wind cycles all the way to target.

Do either badly and its detrimental to accuraccy. some rounds need fl sizing fairly regular, some never need it at all. I shouldn't neck size any hunting round that headspaced on the shoulder as a tight bolt drop can be the difference between one or two foxes down or worse in the case of dangerous game ( i speak from experiance on that one). Important not to over do it though via pushing the shoulder too far back, i now use different spec (thickness wise) set of competition shell holders to adjust as its hard as heck to get it right first time otherwise.

I only neck size and I use .270, .243 and .222

never had an issue with tight brass either in or out. unless the bolt was stiff on lifting why would it be stiff on neck sizing/reloading/rechambering?

entirely down to brass quality and charge levels.

 

DG is not quite the same given the hot climate usually encountered.

 

cant comment on "the majority of BR shooters FL sizing", can think of plenty of reviews by those that know more than me advocating the use of neck over FL in competitive situations though.

I know the lower part if the case can swell slightly on the hornet. This could be down to the relatively thin case walls,the high cup pressures reached by the topend max loads and the general condition of the chamber fireing it.

but is easily rectified by either a fl size or a body sizing die and a probable case trim Before returning to neck sizing only.

 

Thanks Karl.

keep your loads sensible and this goes away.

Now that's not fun at all he he

Some of the most accurate loads with the hornet are compressed loads @ 110 - 115 %

 

[Bewsher500]

compressed loads need not be hot ones.

 

I have the compressed 90 gr loads for the .270 that are well below max
