Started my load work with Nosler bullets today and only tried the 210gr Partition using three powders IMR4350, H4350, IMR7828. Best accuracy for the day was no better than 2 1/2" group and best velocity was 2936fps.
Will be adjusting OAL and also using some RL-19 that I have not used yet. If the RL-19 and adjusting OAL on the H4350 load does not improve accuracy of the 210gr I will be focusing on the other Nosler bullets I have.
I will be testing tomorrow the 200gr Accubond, 250gr Accubond and 250gr Partition. Have already completed the the load work with the 215gr Sierra SBT using Remington Brass, 215 Fed Primers, 73grs of H4350 with accuracy ranging between 1/2" and 7/8" at 100yds, moving at 2907fps.

Well, the process continues with some good new today and some not so good news.
First the 200gr Accubonds shot good and I got good velocities. Using only IMR4350 and H4350 today with the 200gr Accubond I had the following results.
200gr Accubond, Remington Brass, 215 Fed primers, IMR4350 (start at 71grs work up), .879" group moving at 3019fps on average.
200gr Accubond, Remington Brass, 215 Fed primers, H4350 (start at 70grs work up), 1 1/2" group moving at 2989fps on average.
250gr Accubonds were not accurate and velocity was only 2601fps and 250gr Partitions shot a little better and velocity was only 2606fps using for both bullets H4831sc.
I will have to wait for my new brass to get here to continue my work but I am going to use the 200gr Accubond on deer instead of the 215gr Sierra and using RL-19 and RL-17 (if I can get some 17) might increase velocities. If it does and accuracy stays the same or improves the 200gr Accubond is a player. Also, will continue to work with 210gr Partition using RL-19.

Just glancing at records I kept it seems I was getting best accuracy from heavier bullets and slower powders.I see RL- 22 listed.I may have been trying to slow erosion.At any rate I see nothing under 1 1/2" groups.Definitly good enough for any hunting situation.Your posts are intresting.Please keep us informed.Lotta work,huh? ,,,sam.

Yes, it is a lot of work and cost a lot but at least when I get to the field I don't have to wonder if I am going to hit my target. I am going to try some RL-22 with the 250gr bullets soon.

Back in business, my 50 pieces of new brass came into today. Will be trying RL-19 with the 210gr Partition and RL-22 with the 250gr Accubond and Partition. Also will be using Rem 9 1/2 Mag primers.

Just a slight change in my approach than was planned.
Tomorrow morning I will be testing H4350, IMR4350, RL-19 with the 200gr Accubond and 210gr Partition using CCI250 primers. I believe I have corrected the COL for the 210gr Partition, should have better luck tomorrow with this bullet.
I will be testing RL-22 with the 250gr Accucbond using CCI250 primers. Also, have adjusted the COL of thie 250gr Accubond giving it just a little more of a jump than before.
Yes, tomorrow should be fun and interesting.

This morning was quit a revelation to say the least. I tried RL-19 and H4350 in a head to head battle in the lighter bullets 200gr Accubond, 210gr Partition and 215gr Sierra SBT.
First - the CCI250 primers using the above powders and Rem New Brass gave more velocity and better accuracy than the 215 Fed primers in my Ruger Mk II 338Win Mag with a 24" barrel using the same powders, bullets and brass.
Second - the two best preforming bullets in my Ruger were in this order - the 200gr Accubond with an COL of 3.407" giving a group size of .685" moving at 3047fps on average in front of H4350 using Remingtion New Brass and CCI250 primers. The 215gr Sierra SBT with an COL of 3.400" giving a group size of .789" moving at 2972fps on average in front of H4350 using Rem New Brass and CCI250 primers.
Third - with the 210gr Partition I did not get good accuracy and RL-19 with a compressed charge only gave me 2879fps where as H4350 gave me 2948fps with a compressed charge and neither powder gave an accurate group but the H4350 load was more accurate with the CCI250 primer than with the Fed 215 primer.
Fourth - the 250gr Accubond with a max charge of RL-22 only gave 2678fps and accuracy was not better with this bullet than the last time I tried it with H4831. The 250gr Partition is more accurate and gave similar velocities.
I need to try and will after my hunt in Missouri on white tail, the 225gr Accubond and Partition. The 200gr Accubond will be the bullet I will be using in Missouri. At 3047fps what ever it hits it will rock and shake it for sure.
After three days in a row of shooting the 338Win Mag I think I will give my shoulder a rest

I have been at the bench 4 straight days now with the 338Win Mag and my shoulder is beginning to notice the 338Win Mag that is banging on it
Something was nagging me concerning the 210gr Partition and not being able to find a combination that would work in my rifle. Now my rifle is a Ruger Mk II out of the box, no bedding or trigger work, not a bench gun for sure, so I was not expecting much but did want hunting accuracy. It is very picky when it comes to the 210gr Partition but I just could not stop until I at least knew it was hopeless and had tried every option I could imagine.
So I went back to an old Lyman load book and notice they were getting accuracy with Rem 9 1/2M primers and with the lighter bullets it was the 4350 class. So I loaded up IMR4350 using 74.5grs and H4350 with 73.5grs (these need to be worked up to). IMR4350 gave 2972fps which was outstanding but accuracy was not there just like before. So I though great, here I am and it is not getting any better.
But with H4350 I had a 7/8" group (might have been tighter but recoil was a factor being the last group after four days of abuse ) and it was moving at 2936fps which also good velocity. Yes, I finally have a hunting load with the bullet I wanted to use. Here is a picture of the group, chrony and the brass.
Three shot group 210gr Par, Rem brass, Rem 9 1/2M primer, 73.5grs H4350
