EtronX update 107 smk WOW
Well I finally had some time and good conditions today. I went out back to my range and shot the 107 loads I refered to in a previous post.
load constants: Hor dies, New win brass fls., OAL 2.890, 107 smk. Listed in order of firring, no cleaning between groups, and shot without alowing for any barrel cooling time. About 2 min. between groups to make notes is all.
#1 45gr rel22, vel. ave. 2807fps, es 25, 100yrd 5 shot group, .614 in.
#2 43gr H4350, vel. ave. 2949fps, es 35, 100yrd 5 shot group .560 in.
#3 47 gr H4831, vel. ave. 3030fps, es 28, 100yrd 5 shot group .952 in.
As far as I can tell from running my cleaning rod in the bore twist is 1 in 9.5. So I'm pretty impressed with the accuracy results. I was told I would need at least 1 in 8.
I did very little in brass prep for those loads, because I wasn't expecting much with my twist rate. No flash hole deburring. no primer pocket work. Just fls, trim, chamfer, and load.
So I never shot smk's in any of my guns before here is my questions:
Why did they stabalize in my twist rate?
Do they usually shoot this good with such little effort?
Are all the other steps in percision reloading worth it? ie, neck turning, brass sorting, ect.
Before I shot the smk's I tried 3 different bullets; b-tips, v-max, barnes xlc, and all groups were just around or over the 1 inch mark.
I would never have thought of using smk's until I read the information on this forum. So once again I need some opinions and advice from you guys so I can learn more.
