    Try this .243 Winnie-Pooh load, Ackman: 62 grain Barnes Varmint Grenade backed with CCI 250 primer and 46.0 grains of Hodgdon H414, and report back as to how accurate this load is at 300 yards. I believe you will be pleasantly surprised accuracywise. Please indicate your velocity findings at current ambient temperature via a return post, which will help me and all concerned. Cliffy

    Ruger VT 26", 1:9"

    105 Berger VLD
    2.910" (.010" off lands)
    Fed. brass
    Rem. LR primer
    43.3 Gr R17 = 3170 FPS


    105 Berger VLD
    2.910 (.010" off lands)
    Fed brass
    Rem LR primer
    49.2 gr Retumbo (compressed) = 3075 FPS


    80 Grain Nosler Ballistic Tip
    2.800" (.005" off lands)
    Fed brass
    Rem. LR primer
    45.0 gr R17 = 3500 FPS

    I'd never substitute another make of brass with these loads with the exception of maybe Remington as it usually weighs close to Federal, still, better work up to it.

    Okay, my prized, closely-guarded secret revealed: 90 grain Swift Scirocco II bullet backed by a CCI 250 Magnun Primer in a Remington Nickel-Plated case with 44.4 Grains of Hodgdon H4350 powder set at a C.O.L. of 2.687." This maximum load is not for every .243 Winchester, so start at 43.0 grains and work up by .2 grains carefully. Some rifles will Not Like this maximum loading that works so sweetly for me, so back-off swiftly! This is a bolt-action load only! AR-10s, pump-action, and older bolt-actions need not apply, since this is a MAXY-POWER load designed for LATE-MODEL REMINGTON MODEL 700s only. I'm not here to blow anyone's head-off! I reluctantly offer this finding as a Smurf-Killer TOP Load that works for me, but may be WAY TOO STOUT for your .243 Winchester. Learning what's enough power-pressure for your rifle is the KEY regarding TOP loadings. NEVER start with a MAXIMUM LOAD, since it could be OVER-MAXIMUM in any given rifle. Yet, any lesser powder load with a Swift Scirocco II bullet WILL out-power most other .243 Winchester bullets downrange. A word to the wise should be adequate, since we are loading premium warheads for medium game-sized (deer) animals at an honest 300 yard range. We are not paper-target-poppers with drastic gravity-windage-compensation hopefulness of 600 yard, wish-we-could-as-realistic-hunters, loaded for what we seek at truly fair range. Keep expections-in-the-ballpark of range and stalk in closer as true hunters have always had to do to score a proper hit. Just because a .243 load can scream passed a .30/30 load's potential, does not mean one owns the open prairies of Wyoming. Hunting is Stalking: Doubt Not. Cliffy

    Big Pig Load: .243 Winnie Pooh with 24" barrel and 1-in-9 1/8" twist, typical Rem 700 CDL Model barrel. Hornady Case - CCI 250 primer - 105 grain Speer Hot-Cor Spitzer - 45.5 grains Alliant RL-22 - C.O.L. 2.600" Works for me, as one of my favorite loads. Also for the BIG deer hunt: .243 Winchester - 100 grain Speer Grand Slam - 43.2 grains Hodgdon H4350 - CCI 250 primer - C.O.L. 2.600" - R-P brass - Hits with the sound of a 2"x4" piece of lumber striking a wet, hung carpet as hard as one can swing said piece of wood (quite distinctive). Can also be used with 46.0 grains of Alliant RL-22 with equally devestating effect. Cliffy

    Tc encore prohunter

    I use 7mm-08 brass and neck them down to 243 which creates a false shoulder and makes them tight in that break open gun then a regular 243 load for a 70 gr bullet

    Here is my load for the 243 ai and anybody using it should work up to this and not use it as a starting load.

    87gr hornaday bthp
    54 grains of Magpro
    cci200 primer
    c.o.l. 2.670
    3380 fps

    this was shot on a 40* day

    Rem Model 700 VS .243 AI (factory barrel)

    Win Brass

    Fed 210M primer,

    51 grains H4831sc

    85 grain Sierra HPBT Game King.

    2.72 COAL

    No pressure signs...

    I dont know the velocity, No Chrono. But best guess by messing with a JBM Ballistic chart after a day at the range is 3300ish FPS. This load shoots very tight groups in my rifle. A 200 yard zero puts me on at 550 Yards with 10 inches of dial up.


    Took a deer at 404 yards with this load last season.

    [​IMG] Crappy cell phone pic.....
    200 yards in erratic left to right wind. ( last 4 rounds after sighting in at 100 yards after changing rings and base.)

    You may be a little crazy, but you speak the truth about those bullets. I load them in my AI with 44.5g of H414. The print right @ 2" @ 400. Deadly on coyotes and deer. Whacked a yote trotting away from me @ 380. I've worked up a few variations on the load and will report the vel and groups when finished.

    My 243 AI experience has been with Hart 12 twist with zero freebore PTG reamer, .2435 throat.

    Win 760 in a formed Rem 7/08 case, CCI 250, 70g bullet, AA2700 is a great second choice.

    Fire forming load is 47-47.5g of Win 760, 70g Nosler-tnt-berger 69's touching the lands.

    28" barrel yields 3750 fps, groups in the high 3's.

    Formed load-48.0-48.5g of Win 760, 69-70g bullets at 3800-3850 fps, never full length size the case. Change to a Win mag primer with 49.5g of 760 with the 7's an you will be in the 4000 fps area.

    45.5g of Win 760 with a 85g Sierra HP in a formed case yielded 3550 fps, groups in the high 2's and low 3's.

    With the 60g HP, CCI250's, 4400fps with yields a single bullet hole. The 60's at 4400 detonates chucks and large jack rabbits.

    I have read a lot of how a guy needs to use Lapua brass to shoot small groups in this caliber...not true. The loads listed above will agg in the low 2's with three shot groups with Rem 7/08 brass. I have .268 neck dia on my reamers.

    I have never used my full lenght sizer in this caliber cut with my Match reamers, and I have had over a dozen Hart 12 twist barrels.
