Hi' guys, I've done some reload for my father .303

The load was from 42 to 46 gr of IMR 4350 pushing a

174 gr. Hornady Round nose...

My father I shooting everywhere (about 15 inches groups)with those,,no groups that was really tighter than the other..

So the problem Is that Is friend made some for Him using the same combo... And It was shooting great ...about 2 inches .. at 100 yards

So I'm wondering What could I have done wrong If I was using exactly the same powder, same bullet, and same primers and about the same lenght checked with a caliper.. Is it in the sizing.. I've fullsized The Brass And I don't know if my father's friend have done or just Necksizing But could it have a such great influence on shooting....

All thanks in advance
 
Pls. clarify....how much powder did you use? 42 or 46grs. or just approx. 42-46 grs., that would do it. Did the groups spread out vertically? Same cases(same make), same primer? So many questions, so little time!!
 
No two loads will shot exactly the same in any 2 given rifles. The extreme you are talking about though leads me to believe the rifle is the source of the problem. Does it shoot well with other loads or factory ammo? Check everything, sights, stock etc to make sure that they are all up to snuff. Clean the barrel with a copper cleaner like wipe-out or Sweets. If it still won't shoot it could be a barrel issue.

Just re-read your post....like Ben said if you are shooting bullets that are loaded with anywhere from 42-46 grains of powder and not all the same that could be the issue right there.
 
Sorry my friends If wasnt clear... The rifle is the same that was shooting in the two cases.. I was building the recipe for that rifle but in the book the recipe was 46gr.. And those made by my father's friend was also 46 gr... And was shooting great from my father's rifle.... I made them perfectly the same,,, Same powder...same primers... same bullets adn same lenght.... And also the same brand of cases... With commercial load is also shooting great ...The trick is that she in not shooting well only with those I made for it....That's why I was wondering If it could be in the sizing process that could be the difference....

all thanks in advance
 
This defies any logical reason of what is happening. I don't think any of us from two thousand miles away, can help you.
 
Have you actually checked the diameter of the bullets. Any chance you have some .308 cal bullets rather than the proper diameter for .303 British?
 
Sounds like something happened to the rifle after shooting your freinds ammo. Its actually difficult to get 15 inch groups with any ammo/rifle combo....

The gun shoots well with factory.

The gun shoots well with identical loads created by a third party.

The gun shoots 15" groups with your ammo using the same components.

If all of the above is correct, I would like to ask if you weigh each charge, or are you relying on a possibly defective powder measure?
 
Are the fired cases showing signs of excessive pressure or failure? Perhaps as was suggested above it is a rifle problem rather than an ammo problem. Check that the sights are mounted tightly and are not moving. Check to see that the stock screws are tight. Check to see if the crown of the barrel was damaged. Check to see if the barrel is badly fouled. Many possibilities beyond your loads.
 
"...Is it in the sizing..." Nope. It's in the technique. Weighing each charge and carefully seating the bullets. A crimp may cause poor groups too.
 
Trust me, there is no way that something like weighing the cases and making minor tweaks in sizing or crimping is going to bring a 15 inch group down to a 2 inch group.

At most, fiddly tricks like weighing and sorting the cases and neck sizing will improve groups by a few tenths of an inch, more noticeable at longer ranges where velocity variations become more important. Considering the basic accuracy level of a Lee Enfield to begin with, I doubt any of these benchrest tricks would even be noticeable at the best of times.

If you are sure that all the components are the same, and the powder is properly weighed, then the problem HAS TO BE with the rifle.

Personally, I've had experiences with old Lee Enfields where one day it shoots amazingly and the next day, using the same ammo, it opens way up.

I think you should check the bedding on the rifle, and make sure that the bore is properly clean (and then properly fouled in). I suspect that your barrel may be the culprit, but that's only speculation because I haven't seen the rifle. In almost all cases like this, I've found that thoroughly cleaning the barrel makes a huge difference. And these bores are so rough that it takes a great deal of work to THOROUGHLY clean the barrel.

Also, check the scope mounts and make sure the scope itself has not broken loose inside.
 
thanks guys.... I really carefully check the powder charge everytime... I make it as precise as I can.... I will try to clean up the barrel... And try it another time....

You should definitely not let your dies have ### while you are reloading.
