gona do some 75gr sierra hollow points

[Evan03]

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
