100gr bullet in .243Win – load development. Reloading for my deer hunting rifle: RoeStalker

FL sizing cases, see my previous videos to find out why Brilliant new Lee Ergo Prime I need 100gr load and went for N160 powder I have 5 different loads – 4 rounds each to try Sierra ProHunter bullets are flat base and one of the shortest, so
should hopefully stabilize in my standard twist rate .243 Win barrel I seat them quite deep, they were touching lands with Vihtavuori manual recommended OAL Sinclaire hex nut to measure to ogive not to tip 5 loads starting from 39gr in 1gr increments First 39gr load Inspect cases for any sign of pressure 0.6″ (15mm) group Second 40gr load I forgot my rear bag (well… a sock filled with rice… ) 1.1″ (28mm) group Third load 41gr on N160 No signs of pressure 1.1″ (28mm) group Fourth load 42gr 0.9″ (24mm) group Last 43gr load 0.8″ (21mm) group

  1. Well that last group looked pretty good, load four more of that one and shoot another group or two. As for Barnes bullets Setefan mentioned, The 85 gr and 90 gr 6mm bullets are the go to bullets for a lot of deer hunters here in the States. You could do endless load development, I know been there and done that. All four of those loads are plenty accurate to shoot deer size game with.

  2. Thanks for sharing G. I just went through the same process with my .25-06 for same reason. Been difficult for me to find a day with low wind recently. Good luck with the rut and the rest of the load process.

  3. .25-06 is another thing I would like to try at some point…
    I saw two stags last night, but very mild and quiet no roaring. Could shoot both, but no way I could get them out so they stayed for another day.

  4. I will do that just to confirm. 100gr is legal requirement in Scotland, no ideal I know, but I dont have anything bigger than .243 at the moment and have to live with that.

  5. My previous .308 it shot well with 150gr Hornady SST and 180gr Speer BTSP. I also have a box of 165gr Nosler Accubonds I never managed to try, I think they should be good on reds.

  6. greg watching your videos finally encouraged me to try home loading.i have never seen you using ear protection when testing loads why not?

  7. hi nice video,i have bought a box sierra pro hunt 100grs in 243win an i have a box of n160 powder my rifle is rem 700 sps what kind of load shuld i juse minmax

  8. Awesome Video. Just purchased some 95 grain sierra matchking. tried the 105 grain bergers and the rifle didn't like them.

  9. If I could figure out how to post a picture I would. It took some playing with the bullet length. And I came up with 0.37 grains of H-380, win brass, CCI primer and COAL of 2.775 I was getting sub moa groups at 100 yards.

  10. HI:) IMR Powder IMR 4350  Bullet Diameter .243"  C.O.L. 2.650"                           
    Starting Load Grains 38.5  Velocity (ft/s) 2,760  Pressure 43,000 CUP 
    Maximum Load Grains 42.0  Velocity (ft/s) 2,958  Pressure 50,100 CUP
    Use Winchester WLR primer, 100gr Speer BTSP Don't use  CCI primers because they burn with about 6000psi less pressure so use the Winchester primes for best out come. Winchester WLR primers have around 12000psi more pressure than Remington 9-1/2 primers and CCI and Federal are in the middle. This is why primer type is important.

  11. Hi , I am looking for a load for my cz 243 using hornady 100grn BTSP , I have vit n140 .. Can anyone advise



  12. we need 9-10g and min. 2700j/100m (140-155gr 1991ft/lbs/109y) or 10g+ 2000j/100m.
    (155gr+ 1475 ft/lbs/109y)
    min. caliber .260 rem or 6.5×55.

  13. many years ago I loaded an 85 grain sierra BTHP for groundhog hunting with 36 grains of IMR 3031. It was pretty hot and extremely accurate out of a model 70 Winchester. That gun could handle it, but I started at 33 grains or so. I tried IMR 4064 with 90 Grain FMJ with about the same (following the reload manual) with Winchester cases that were once fired and it cracked the neck of the case every time. No idea why.

  14. witam. czy elaborowal pan pociski hornady sst 95grain w 243win prochem vv n160 bo nie moge manualu znalesc nawazki i o.a.l. DB.

  15. Nice Zeiss scope. I had a similar Zeiss Diavari in 3-12 x 56mm. When testing loads, you need to fire at least 3 or 4 five shot groups for accuracy. Statistically, one group won't do it. Looking at my old notes for a Ruger No. 1 (26" barrel) in a 243 Winchester, I used 70 grain Nosler Ballistic Tips and 100 grain Nosler Partitions, intended for varmints and medium game, respectively. Using the Nosler No. 7 manual as my reference: For the 100 grain Partition, with Remington virgin nickel cases, separated by weight, Win WLR primers, cases trimmed to 2.035" and COL of 2.675" (bullets seated .025" off the lands). I BRIEFLY went up to 47.0 grains of IMR 7828, (their most accurate powder for that bullet) and got 3195 fps . However, the maximum load for IMR 7828 was 45.5 grains which gave them 3123 fps. My gun, despite having a barrel 2" longer than their 24" Lilja, nevertheless, produced slightly less with the same load. Just shows you that the old saying: "Without a chronograph and micrometer, you only think you know what you are doing" is true. All the groups were around moa.

  16. 243 is my favorite caliber. I don't do much hunting anymore but i have down two deer, one whitetail and one mule deer. I used a 100 grain nosler partition for both. The first was about 125 yards, it ran 75 feet or so the second was 275 yards, it went straight down. Both heart shots. I also killed two coyotes with a 70 grain nosler ballistic tip. They both dropped instantly. It's a great caliber.

  17. Ha,ha ,you must change your skill , to close thee left eye while looking tru the scope is the wrongest habit you can do here :-))
