Well....not a bad start at all.  Pretty much every load is sub deer.  I had a couple that have great potential with a little tweaking.  The first picture is of all 3 round groups for the 190 ABLR and 200 gr AB.  The second and third pics are the best sub 1" groups of 200 gr AB with .5 grain apart. 

The last picture is of my 6.5 creedmoor that continues to shoot amazing..... 0.52" 4 shot group.   :tup: :tup: 

Hopeing to be able to produce similar results in the 300 win mag in the coming weeks.

Getting closer to the final load.  Range day today produced very promising results. 

76 grains of H1000
200 grain accubonds
15 - 25 thousandths of the lands so far are producing the best results but still a little work to do. 
2994 fps

1'st group is an 8 shot string to see how the barrel would respond to heat.  First shot is clean bore and then the shots were stringing north but overall not bad.  Also the highest two shots were seated to 5 thousandths off the lands which caused 18 fps faster rounds. 

2nd group is a 6 shot group with two different seating depts.  the single hole is 4 shots....three of which were 20 thousandths off the lands.  other 3 shots were 25 thousandths of the lands.

Its a shooter!  That seating depth looks like its critical for a ragged hole group.  You wouldn't think .005 would matter that much but I've seen nodes only .003 wide.

Looks good. You may pick up some speed after more rounds too.

.300’s are very forgiving. Super talerant to different seating depths. Just a quick heads up when it comes to the 300 Win Mag. Primers are key. Run the same bullet, powder charge and seating depth. Then only change the primer and shoot for groups. Try the load with standard federal 215’s , Federal 215 Match and Winchester Mag primers and get back to me. Allot of guys don’t realize how much primers contribute to accuracy.

Can you tell the difference shooting a 215 vs a 215m?

I agree primers can be key. i went from a wlr to a fed 210 and es dropped dramatically.

I’ll be switching my 300 from 215 m to 215 soon. Almost out of 215m and can’t find any more.

I'm curious to know if you see a larger difference than you would see in lot to lot variation. Most people use the the match designated ones because they labeled "match" so they're obviously better.

I bet you won't notice a difference.  :twocents:

Your thoughts are the same as mine. I may be going to a new lot of powder and bullets around that time too so will have to rework the load data.

Hey rebel if  you want to try some 215 bergers shoot me a pm. I can drop some in the mail for you.

Thanks for the offer.  I have some burger 185 vld hunting I am going to play with.  Took the chrono out today and did not like the SD at all.....running in the 30's, which is just gross.  I will be trying a few different primers next and playing with a lighter bullet to see what the rifle likes.  It should shoot better than I have seen so far.  I guess that is part of the fun of working a new load.

Couldn't find any 215M primers but did try 215 and Remington 9 1/2 mag primers with all else being equal.  Here are the results of the 5 shot groups.  I am pretty amazed and will be hitting the range tomorrow to reproduce the 1/2" group. 

200 grain nosler partition
76 grains H1000
Same seating depth
Did not chrono them but they should be around the 2900 ish fps. 

Can you guess which primer worked better?
