61.5gn - groups not improved. Slight ejector mark but easy extraction. Magnum vs non-magnum primer. Mag primer lower sd. Not much in it.
Will try 61gn and seating depth variation.https://uploads.tapatalk-cdn.com/202...9921363d28.jpghttps://uploads.tapatalk-cdn.com/202...ccfd34d600.jpg

I think it might be time to try a different powder.....happy to relieve you of that useless Rl26 :thumbsup::ORLY:
If you could guarantee tighter groups...! Going to shorten the front mount forward screw, look at sanding out the barrel channel.
Looking at your previous groups they all seem to be more vertical than horizontal but this one at 61.5 has good vertical.....maybe doing a seating change will tighten that up more rather than altering the rifle.
The barrel wasn't well floated so just sorted that. Trimmed the front mount screw as known to touch barrel threads. Also relapped rings as rear was not quite true. Would be nice to bed the recoil lug but not done bedding before so will park that. I'm sure a FDE cerakoted stock would take 0.5" off the groups!
Yes I'll try 61gn see if that has the vertical flyer still - you are right @wsm junkie the 61.5gn group seemed better for that...just getting near max so will play with 61.0gn seating depths.
Interestingly factory new norma brass was often still a firmish bolt close. Stiff to lift the bolt too of course. Even once fired unsized brass could be like this. A strong cam over didn't seem to help so I tried a just touch shell holder die base FL size followed by a run through the body die. The body die just touching the shell holder and a case felt like no work was done but what a world of difference...super easy bolt closure now. @Mooseman may be something for your boy to try...
COAL of 3.330 loads ok but groups were not great. Going to try 3.250 and even 3.200 COAL with 162gn ELDM. This will send pressure up so might back off to 60gn.
I would be inclined to give up with that powder when getting to 120thou jump.
May be a faster burning powder? Rl22 or 23 may be
I had almost the exact same issues getting the 162 to group and changed to the 180 eldm and got .5" groups straight away :)

Deadly combo there.Quote:

Wow that is good and is a go if no joy. I do want a mag fitting round though.
That fits in my mag :)Quote:

Barrel will be toast by the time you settle on a load

outta curiosity was the pulled shot the fastest ?
sounds like you need to load 3 more and shoot it again bud :thumbsup:
Hmm not sure. Didnt get better.
Very consistent speed.

Whats your jump like? I found they liked around 120-150 thou jump.Quote:

Have you considered barrel whip? I know it is a thing with kimbers. Quite often full length bedding or taking a couple of inches off will help
I would be trying heavier projectiles myself. My Montana WSM shoots way better with heavier projectiles than the 165's
Yes I think it might be something like that....looking at getting the barrel rethreaded for my A-Tec adapter. And then someone to bed the action and lug. I think the COAL results with the 150 ELDMs means I'll have a lash with the 162 ELDMs at different COALs first.
FIL next door has a dreaded bore scope so will pop that through too.
That's what I settled on with mine @ 3130 with plain old 2209 after trying all sorts of powders. Kills very well- last one levelled at 565yds and cartwheeled down the slope.Quote:

I am very surprised there isn't a wider range in speed... there should have been 30-40fps or thereabouts going from 3.325 to 3.215.
Have loaded up some seating depth loads using OBT. Had to try the ELDMs anyway so why not OBT. One small thing...I am using new brass and like to put a wee mouth chamfer on before running through the sizer... had that wrong way round.
Borescope showed polished barrel, no copper or surprises. Slight pitting one side at the muzzle. Will get new thread cut so will sort that. Might look at going to 22" as the speed is there to play with from 24".
Thanks to @burtonator some 180gn ELDMs over 59gn RE26 to try with my 162gn OBT loads.

Will be interesting to see what speeds you get from them!!Quote:

What length are you going to chop to?
22" and hopefully enough meat there for 5/8x24 barrel adapter.
Well...barrel bedded, barrel chopped to 22" and A-Tec QD suppressor on it now. Tried ladder with 180gn ELDMs and RE26 starting at 58gn and going up in 0.2 increments.
Split the ladder test into 3 shot groups. First group nice triangle shape 0.8MOA. Keep in mind last time I shot 180gn I stopped after the first 2 shots that were 2" apart.
Definitely showing some promise.

Looks promising n good speeds too
Yes not much of a drop. I did forget to run the brass through a body die.
