Just wondering if anyone had similar experiences, if so feel free to share


I have had company for couple weeks so load developing was outta the question so I tossed together a trail load since I had a brief window this afternoon.

test load was

243 win with h414 powder 42 dribbles of it and topped off w a hornaday special, one an only 80gr gmx.

before I had tested the barrel w 85 serrias game kings and was able to drop them in under a 25 cent piece.

so you could understand my dumbfoundness when I chambered one of dem gmx and let it rip and to look down range and see no holes on the sheet.

let another rock and low and behold a hole has found its way on the paper.. "hmmm.." I ponder "interesting this is..."

being as I had only thought to load 4 for pressure and accuracy testing I let them all find there way down range with no others touching paper

"odd" I murmered " surely the wife isn't that rough with my guns"

"rings come loose?" I question "weird to shake mounts that are on a 14lb 243 win"

so after much think and head scratching I do the logical thing

having 4 rounds left that have before shot half inch I go and fetch them from downstairs and being slightly weighty and outta puff I proceed to shot those 4 in to a

group around an inch.

so something about those loads made my rifle have an allergic reaction.

heres a pic for yall to gaulk at

I chalked arrows where 4 went that had similar qualities like buckshot

sounds like a bad load for that gun, mine have been crazy out, but what i don't know is specifics

How far were you shooting?
How windy was it?
What specs were you loading them to, like how did you find out how far out to load the bullet in?

Id be leaning twards your load with wayyyyyy too much pressure, might be throwing your barrel harmonics way out of whack
 
Very strange, indeed.

I have a Vanguard in 300 WSM, and the 165 GMX is one of the most accurate bullets in that rifle.
It shoots everything quite well, but both the 150 and 165 GMX are always in nice, tight groups.

Maybe you might try another powder.

It is a possibility that your rifle does not like that bullet though.

As most on here know, I am partial to the Nosler Partition.

I had a 700 CDL in 300 Win Mag, that absolutely hated the 180 partition, much to my chagrin.
I tried several powders with the 180 P, but to no avail...it was about a 3moa bullet in that rifle.

However, it shot the 180 Accubond and the 168 TTSX into 1 moa, so I was OK with that.
Hard to figure sometimes.

Regards, Dave.
 
Yep, don't know what the twist is in your barrel, but it did not stabilize the bullets.
No use trying any other loads with those bullets in that rifle.

100 yards breezy I always load a touch off my lands being as I planted the target barrel on a savage long action..

no high pressure signs what so ever

I lied . the barrel is marked as a 12 twist. guess that is to show how bad an accurate rifle can really shot

What model do you have? Savage shows just about every .243Win of theirs as a 1:9.25 twist

As stated in the other thread in this forum, i tried everything from 58gr-105gr with the best performing factory load as Hornady 75gr HPs'
For whatever reason these Savages just agree with that 70-90gr range. I'm using IMR 4064 in my loads.
 
its a model 12 varm barrel orig chambering was 6mm norma br then redone to 243. its the only 12 twist they make all other 6mm br's were 8 twist. would have rathered that however...
 
I think you've answered your own question. You have to use shorter bullets in that 1:12 barrel, regardless of their weight. A flat base, lead core bullet with parallel sides and a flat or hemispherical nose provides the shortest length for any given weight in caliber, whereas things like mono-metal construction, boat-tails and secant ogives tend to be the longest bullets. Your rifle has proven to be deadly accurate with the Sierras, so the math is pretty simple on this one.
 
1:12 that's what earned the Rem 244 a bad rep.
They wouldn't stabilize anything but light bullets. The latter re-branding of the 244 as the 6mm Rem also saw 1:8 twist barrels

243 is a phinicky cartridge for pressure. It's like the 7mm rem mag, pressure can jump up in a hurry for some reason.

Just sounds like a poor load to me, try a slower burning powder.
