Just started making a load for my 243. Im not an expert reloader but know the basics to get it done, but I could use a little help. I have tried different OAL, and different powder amounts. I am still getting the same results with 3 different charges. I am not showing signs of high pressure, so should I just keep going with higher loads in .3 grain increments? What usually causes this type of grouping?

Could be 'bore condition', bullet selection, twist rate, damaged or uneven crown, brass consistency (length, neck thickness, primer vent), 'operator error' (pulling a shot).


Any one or combination of these things will affect your grouping.



Good luck. Just be safe. smile

What powder are you using, how far are you of the lands , what weight and make bullet ?????? The info here is a little slim to make any recommendations.

I had an old Mossberg .243 that would not shoot any bullet under 90 grains worth a darn. Loaded with 95 or 100 grain bullets and it shot great groups.

buy a box of factory bullets see if they shoot any better. lots of things could cause those groups. loose scope screws, poor scope, poor shooter, wind, poorly bedded action/barrel, inconsistent case length, inconsistent powder charge, bullet seating, bullet choice, powder choice, mixed lot of brass etc

shoot some 5 or 6 shot groups 3 is to small to really confirm a pattern

what I found on a rifle I have been working up a load for is that it shot 2 groups , a freind found this with his also.

it took me some time about 80 rounds to fully identify the pattern but if I was really sure to hold it in my shoulder tight like if I used a sling it would shoot one group

one of the groups would shoot was low and right of the other group

on several of my 5 shot groups 2 would be in one place 3 in the other I finally figured it out

1 is where it free recoils to , 4 is 4 rounds 3 holes and X is where I wanted all 5 to go this is at 100 yards and the grid is 1/4 inch it is a 308
the stock was just a little short , if the rifle free recoiled it was up and left if secure in my shoulder right about where I was aiming

since you can't recreate free recoil every time , it requires making sure to hold tight every time , I added 1/2 inch more recoil pad and it is shooing more consistent one group and not 2

Try it again with factory ammunition and a lead sled or some good sand bags set up just for you !

I say also go with this and then see what the gun dose. it will give you a idea of how the gun shoots. Then you have a base to work with when you do reloading.

Try drawing a 3’’ square and color in use one of the corners as your point of aim this will help your groups it’s hard to have the same point of aim when just aiming at a circle ⭕️. The amount of powder difference you are doing could make a difference but it will not do much for me the OAL makes the most difference my best grouping rounds will not fit in the removable clip when using the nosler ballistic tips they are about .015 to long but if the load book is call for 48gr. To not be exceeded load 3-5 at 46gr and the other 3-5 rounds at 47.5gr you will see a difference but if you are not trimming your casings each load your seat depth will never have constancy and also for me the first or second time the casing is fired may not be the best groups my 243 likes 3-6 time fires casings I like the H 414 powder or the IMR 3031


Your only as good as your last job!!

A lotta Variables there to guess...
But if its throwing a flier on the third shot or so , its probably the barrel heating up, and the Molecules expanding and moving in the Metal as it heats so to speak... Try giving it a little more cool down time between individual shots , dont just burn off 3 shots quick.
Most likely just the barrel heating up and walking a bit. Cryogenic freezing and heat curing the barrel with help combat the problem sometimes.

I wouldn't waste my money on factory ammo unless you plan on spending a bunch of money to find out what your gun likes. Your would be better off buying more components. It may be a bedding issue. Check all your screws (action, scope, bases). Try working the load up to max or down to the starting load. Try a different tip. You may have found a load your gun does not like. Is the scope good?

Make sure you are holding the gun the same for each shot. Don't wrap your finger over the barrel either. Oh, and don't flinch.

I have groups similar on all my rifles. Always ends up being the shooter, me. Most rifles are more accurate than the shooter. Shot a few rounds, walk to the target instead of using the spotting scope. Give the rifle a few minutes to cool.

It could be so many things there is no way for us to know, but there are things you can do to narrow down the source of the problem. I suggest you shoot every shot through a chronograph and record the data for each load. If the problem is with your loads and not your shooting or the rifle you should see better groups with the loads that yield better statistics (lower extreme spread and standard deviation). You do need to shoot at least 5 shots with each load. A chronograph costs about $100 and will pay for itself over time if you continue to develop loads. The best load will have good statistics, not always the best because barrel harmonics play a big part too, but will be very close to the best.

When shooting make sure you have a good rest and the rifle is positioned the same on the rest for every shot. I let my rifles cool for 3 minutes between shots using an old fashioned egg timer to track the time. Also, if you load a round and something delays the shot, pull that round to let it cool and load a fresh one.

Unless you know the twist of your barrel everything is pure speculation at this point.
