    Do Federal 210 Match Primers perform better for this cartridge? It seems that most of the loads listed use F210M's...........

    .243AI load testing data:

    Savage Varmint Action - 28" Criterion 1" bull barrel (w/550 rounds down the tube) reamed out to Ackley Improved

    Powder - IMR 4350

    Bullet - Hornady 105 A-Max seated aprox .025 off lands.

    5 shot strings

    41.6 gr - 3051/3058/3058/3065/3079 FPS

    42.0 gr - 3065/3079/3102/3100/3108 FPS

    42.4 gr - 3112/3122/3137/3128/3115 FPS

    42.8 gr - 3144/3137/3144/3144/3150 FPS

    43.2 gr - 3152/3167/3167/3162/3182 FPS

    I did 2 separate ladder tests @ 265 yards and decided the lowest load and near the highest load showed the best potential so I loaded up 10 rounds @ 41.8 gr and 10 rounds @ 43.0 gr and shot some 5 shot groups @ 225 yards later in the day and the 2, 5 shot groups of 43.0 gr produced right at and just under 1" groups running right around 3150 FPS +/- 10-15 fps.

    I wanted a 14 twist but all I could find at time was 12, does anyone else but Shilen offer that twist, in 6mm I am surprised to hear of someone going that route, I thought I was they only one that would spec out a 14 twist 243AI, sorry I can't help you I only have a 12twist, but will watching to see who chimes in, just glad to see there are other slow twist shooters out there, we should have our own forum section,LOL

    Have owned and loaded for many, many standard factory .243's over the years. Most were Rem 700's with a couple of Model 70's, one Sako and a Ruger #1 thrown in for good measure; Most (I assume) were 1 in 10" twist barrels. Without fail, my go-to load has been either a Hornady 87 grain Spire point or a Sierra 85 grain HPBT with a prudent load of H414 or WW760. Devastating on Whitetails and groundhogs alike.

    Quick question for everyone, I'm not having any luck finding Unique around here to use for COW loads so I'm trying to find an alternative. I've seen blue dot used but yet again I can't find any, however I was looking at burn rate charts and I noticed W231 is very close to Unique and I have some on hand. So has anyone tried using 231 and if so what did you settle on for charge weight. I was thinking of staring at around 5gr and working up till I didn't notice an improvement on forming. I was thinking I would end up somewhere around 9gr, but wanted to bounce the idea off people that have tried this a little more. Thanks for any help.
