Thread: Factory .243 that WON'T stabilise 100gr !!

    Factory .243 that WON'T stabilise 100gr !!

    So now I am intrigued

    Seems the other thread has successful stabilisation of 100gr rounds from the following manufacturers:
    Sako 75/85, Tikka, Ruger, Savage, CZ, Howa
    in a range of bullet makes

    So what DOESN'T work with 100's?

    cue tumbleweeds......

    I'd be surprised if there is a modern UK marketed 243 out of the box that couldn't!

    Haven't read the other thread but I still have a Dumoulin 243 that will shoot 85g Federal Premium Grade HP BT's into 3-shot half inch groups all day but if moving to 100g of same manufacture they are (or perhaps I should say were as this is 20+ years ago!) all over the target with clear signs of tumbling. However, if I use 100g RWS they too shoot keyhole groups.

    Oh, and Richard W, formerly of Chris Potter Guns, is my witness!

    I've owned quite a few 243's over the years made by Sako , Mannlicher Schoenauer , Remington , Winchester and Ruger . I gotta say they ALL handled 95-100 grainers no problem ! I've owned several rifles from Remington chambered for the 6 mm REM that handled the heavier 6mm billets as well . The only one I ever had that wouldn't was a circa 1958 Remington 722 in 244 REM with the 1-14 twist , but then I was well aware that the slower twist wasn't supposed to handle anything over 85-90 grains anyway .

    Whilst my Tikka T3 will shoot sub inch groups with Sako 100gr, the 1st 100gr I tried was Hornady Interlocks and the target looked like I'd used a 20b with BBs through an open choke.

    I must have had the ONLY Sako lemon .243 in the Northern Hemispere,It refused point blank to digest anything over 85 grains........... barn doors were very safe after this weight. anything 85 & under was a bughole job!

    My tikka 595 will shoot hornady 100grn reasonably well. Then i tryed sako 100grn and they were top notch. I tryed 95grn and they were one hole groups. So found when i back off the 5 grns it made my groups alot better. So my gun can do it just not as it can other weights.
    Always think before you pull that trigger.

    I had a very early Tikka T3 Hunter .243 that wouldn't stabilise anything over 90g, it really was a scatter gun with 100gn bullets. My shooting pal had one 5 years later that was fine.

    I nearly posted a thread along these lines the other day.
    Not only have I discovered that my 1-10 Steyr Scout will group 100g ppu, 70g Nosler federals and 58g Norma vmaxs but it also does so within 1moa of each other.
    Tie this in with a ballistic app and you've suddenly got an incredibly versatile rifle for pretty much anything.
    Almost feel bad that I've tied it up with NV now

    My Heym sr20 groups RWS 100gn, Geco 105gn all day long into 3 touching holes type groups. Federal 100gn opens up to 3".

    Because the 243 is quite a small calibre, operating at high pressures and high velocities I would suggest it is quite picky in terms of choice of ammo, and hence the growth of the myth that it doesn't like 100 gn bullets. I would ask those whose 243s don't group 100gn bullets, how many have they actually tried?
