I do have some RL22. Going to push the H4831 a bit harder and change to starline brass.. ladder test loading up. RL 17 looking very promising at 54.1-54.4. Right at 3100 at very consistent V.
Right now RL17, Norma and Barnes TTSX
h4831, starline and SGK.
If I get that Starline SGK...
3.217 is running about 1.25”. I’m about 0.140 off the lands. So long ways from the minimum recommended 0.050”
I’ll run up to the store tonight to see if I can pick up a box or two.
So I measured distance to the lands with the TTSX and got 3.355”. My test loads were 3.217. Barnes recommends min 0.050” jump,
So I’d start at 3.305, 3.295 3.285, 3.275, 3.265, 3.255, which would cover 0.050-0.100” off lands, is there merit I going further? Trying to not run out of TTSX just...
Thanks Jim. The only issue I’ve had is getting the dioptic adjustment right for my eye… it was better this last time out… seems to be a very fine adjustment and I haven’t hit crisp yet… hope too. I do like its size and when I’m hunting I’m typically using 2-4x. Not one to crank the magnification…
That sounds about right… first shots were over a foot high at 25 yards.. turned it about 4 revolutions to get it near target.. so a form of inches at 100.
Thank you very much. I’ve never seen one like that before…
I looked at the bullets rated Mv is 1600-3100.
So next I looked for 300BO recipes for that bullet… and they don’t have them. Instead they had 2 225 grain bullets - both target bullets…
Does that imply the 220 gn RN. #3090 rated Mv 1600-3100 and the only Hornady 308 rated for Dangerous...
Hi.
I got this scope, Leupold Vari-X III, 2.5-8x
I’ve never seen an adjustment like this. No MOA or MILRADs, just numbers..
When I adjusted it, I felt no clicks..
Can anyone tell me what these markings are referring too?
Took it out today with three test groups.
53.8 shot 3085, 3066 and 3100. SD 17, ES 34
Next one gets more interesting
54.1. Shot 3099,3100 and 3105, SD 2, ES 5
Next one right there
54.4 shot 3115, 3121, 3119. SD 3 and ES6
I don’t think I’ve ever had loads in the single digits for SD and ES...
Bought two pounds of RL17 today at Joe Gunn Sanford MI. He has a smattering of powders. rl7,10,15, 19,22,23,25. Took the last two 17’s, and didn’t see any 26.
No signs of pressure at 59 grains… will push it a little harder.. I would like to get it up to speed. Case volume was pretty tight..so not sure I can get far.. but will work up in 0.3gns..
