heres the results

52.5grs of h4350 2"s horrible

56 and 56.5 grs rl19 1.5

57grs rl19 1 1/8"

57.5 rl19 5/8" 3 in perfect traingle

58grs rl 19 3/8"

58.5gr rl19 7/8"

59gr rl19 1 1/2"

59.5gr rl19 3"

startn getn tighter at 57.5 tighter still and the sweet spot at 58 opend up at 58.5 and kept growing to 59.5

all grs are measured outside of hole to outside of hole. all loads where shot from a sand bag with coat under the but

no pressure signs till 59.5 were all 3 cases had shiny spot on the case head where it rides agaisnt the bolt face. i didnt think that was to bad. i was very ready to pop a primer at 57grs and go home.

im very exscited with the 58gr load and will load a few more to make sure it wasnt a fluke before i load up a a bunch.

i did notice something to take note of. the lighter loads shot above the 1" orange dots with ever hotter load it was grouping lower. the 58gr load at hole in the bottom of the orange dot 59 and 59.5 where lower but all over the place so i couldnt realy tell how much lower they are.

how fast do you guys think the 58gr load is pushn the 75 sierra through my 24" barrel its got be movn.

noslers 85gr bt is at 3700 with max charge of 57grs thats already movn right along, id imagine my load of 58grs is somewhere above that.

also about what area do you think its as far as pressure is concerned. im kinda in the dark i winged those loads from nosler manual with just info they had for 85s.

thanks id apreciat any feed back

50cases prepped and primed im very tempted to load all 50 with 58grs and go the range to test out to 300 thinkn 20 is safer incvase my tight group was a fluke.

eitherway im testing to 300yds this afternoon. im off to drop powder and stuff bullets

the 3/8" group must have been a fluke. loaded 35 loads in that powder charge and wenmt back to the range. i didnt manage to shoot another group that tight again but i did keep all my groups 3/4" and smaller actualy thats lie i didnt tape a singleone one so i wont throw any number out there. ill just say all groups passed my aproval.
only shot to 200 groups opend up just alittle. they are very consistent and flat to 200 wich offcourse they are i need to shoot on paper further.

i did manage to scare coyoite with the bullet this evening, had an oprurtunity to put one through the chest of dog that was lookin at me. went through the effort of blowin on the call got em to come in and couldnt make the easy easy shot at 100yds

i was curious to see if the bullet would make it all the way through the dog from chest to tail.

ill have to call again to get some results on fur.

Thanks for the info. I am debating between the exact same bullets you were trying. I am just nervous that the will tear a dog up too bad though. I hear the Speer TNT's are good too out of a 25. They supposedly don't exit.

I think you're going too light with the H-4350. I use a mild load of 56.0 grains with 75 Sierras,and get 3595 fps" and 3/4" groups out of a 22" sporter (that's TWO full grains under max). A buddy uses the max charge in his rifle, a heavy barrelled Savage, and gets 1/2" groups or thereabouts. Give H-4350 another try, with stouter loads, and see what happens.

anything stouter than 58 and acuracy falls off. ive been getting good consistent acuracy with the load through 24" barrel.

i did run the load up to 59.5 it looked more like shotgun hit the paper rather than rifle.

so 58grs is max and right where i settled down. thats good to know.

thanks for the info.
