    Have to give two thumbs up to the 37.5gr Varget load too. 37.7 shot very well too. Both grouped right under .250. Going to try 37.6 this weekend.

    I'm starting to really like 243AI.

    Standard .243
    Rem 700
    87gr. V-Max (HBN)
    45gr. H414
    WLR Primer
    Winchester case
    3,050 from an 18.5" factory barrel.

    This is a warm load in my rifle.
    I tried coating the bullets with HBN, and needed to fire a group to check zero and see how it was working. The wind started to die down right at dusk. I rushed out, set up a target, and tried to shoot in the calm between the random gusts. This is a 4 shot group, guess which shot the wind caught. :) Overall group was around 1/2".

    26 inch mcgowen super heavy barrel 1-10 twist with tight neck and tight chamber on a custom 3 lug single shot bolt action. all testing was 100 yards unless noted. all loads are done using redding competition .243 bullet seating die and rcbs necking die. cases are winchester brass and have been anneled. cases are checked and sorted for weight and length. flash holes deburred and primer pockets uniformed.

    h414 loads:

    85 gr sierra hpbt gameking
    43 gr h414
    winchester large rifle primers
    2.650 col
    very accurate good pressure 1/4 moa

    87 gr hornady v-max
    43 gr h414
    winchester larger rifle primers
    2.730 col
    good accuracy good pressure 1/2 moa

    90 gr nosler spitzers
    43 gr h414
    wlr primers
    2.740 col
    good pressures, hard to keep 1 moa

    75 gr sierra hpfb blitz
    46 gr h414
    wlr primers
    2.647 col
    great accuracy good pressure 1/4 moa

    80 gr sierra spbt blitz
    45 gr h414
    wlr primers
    2.700 col
    great accuracy good pressure 1/4 moa

    85 gr sierra hpbt gameking
    44 gr h414
    wlr primers
    2.650 col
    great accuracy good pressure 1/4 moa
    shoots about 1/2 inch higher than 43 gr load

    95 gr berger vld target
    41 gr h414
    cci br primers
    2.885 col
    good pressure bad accuracy. berger posts that bullets need tweeking. best average group i could get was 2 moa at 100. i will say these are way to long for my rifling. do not take this accuracy as a bad rep for berger. i use them in my 300 mag and they perform absolute the best. this bullet again is to long for my twist rate and was an experiment. this was posted to show the amount of powder i worked up to.

    reloader 17 loads:

    85 gr sierra hpbt gameking
    46 gr rl 17
    cci br primers
    2.650 col
    great accuracy good pressure 3/16 moa
    this is my go load for accuracy

    80 sierra sbt blitz
    44 gr rl 17
    cci br primers
    2.700 col
    great accuracy good pressure 1/4 moa

    87 gr hornady v-max
    44 gr rl 17
    cci br primers
    2.750 col
    good accuracy good pressure 1/4 moa

    75 gr sierra hpbt varminter
    45 gr rl 17
    cci br primers
    2.640 col
    great accuracy good pressure 1/4 moa

    75 gr sierra hpbt varminter
    46 gr rl 17
    cci br primers
    2.640 col
    great accuracy good pressure 1/4 moa
    this load shoots about 1/2 inch high at 100 yards

    these are my "good" loads. i found imr 4895 to yield extreme pressures in my gun with suggested starting loads from the lyman book. most of, if not all, of the loads i have listed are above max powder weight suggested by lyman and hornady. i built the gun to be almost indestructable and wouldn't recommend pushing as high as i have. my good pressure sign is a good primer indent and minimal case stretch. i hope this helps!

    I fireformed 100 243 cases yesterday using the cream of wheat method and it worked great. I used 10 grains of Unique topped off by cream of wheat held in place with a piece of tissue. Each and every case completely formed. I did find that a number of them had burnt cream of wheat stuck in the shoulder body junction and in some cases this was thick. I had to use a pick to remove it. I tried tumbling and ultrasonic cleaner but there was still some in the case. Just wanted to pass that along. Enough of it could cause problems such as high pressures if not removed.

    Savage model 12bvss 26 inch factory fluted stainless 243 win. Favorite long range load due to twist considerations (9.25 twist). Is a 95 grain Berger hunting or target VLD jammed into the lands .010" Using Winchester brass CCI BR2 primers and H4350 at 41.9 grains. Which chronos at 3050fps average. with low sd and es. Groups average 3/8 or less at 200 yards for five shots. As well as under an inch at 500 and 3 inches at 1000 in no wind conditions. I have tried lots of different seating depths and powders but H4350 and .010 jam works lights out. But my gun will shoot very well with almost any powder as long as its jammed .010" I use this combo to shoot golfballs on strings at 500 yards at my friends range for fun. This load makes it easy.

    Greeting from the UK
    My first post here - can anyone help please
    I have just purchased some .243 63 grain Barnes varmint grenade bullets and I am having trouble finding a suitable load .
    The problem is that I only have a European powder (Vit N160) which is good for my normal 85 grain - but US made powders are getting a bit thin on the ground here
    Can anyone help me or will I have to put my hand in my pocket !
    Thanks
    Ed

    Ed, What barrel length are you using? My data says about 47.7 grains or 3.09 grams with a slightly heavier bullet and N160. If you know your case capacity and preferred seating depth I can adjust for that...
