New load problem

I had a load worked up for my .308 with a 165 Nosler Ballistic Tip and 43.0 grains of Varget with a Federal 210 primer that was shooting quite well. If you read my other post, you see I have lost all confidence in this primer, so I bought 1,00 210M primers the other day assuming they were probably close in their performance, but better quality control. Well, I realize that when you change anything in a load you should start load development over, so I did. I went through all of the available charges for this powder and bullet, and nothing shot less than like 2-2.5 inches at 100 yds.... I know this gun will shoot, please help. I have some IMR 4350 and some H-380 I think I am going to try if no one comes up with any other ideas about what I am using now.

Try some IMR-4064, I am having good results with it. At about 41.5 to 42.0 grains with a 165.

Never used a match primer so can't comment on that.

I got some on the shelf that I plan to try though! Looking through Lyman's book, I see their very fond of Reminton primers. There's prolly a reason for that so I broke down and bought some to try.

What are you going to be shooting these in?

I had a group open up switching from CCI primers to Winchester primers using IMR 4350 in an '06. Winchesters are made to light ball powder and is hotter than the CCI's. No amount of work up would help the winny primers. Once you find the sweet spot, don't change it.

don't so fast to blame the powder / primer it may be the bullet .. my 700 won't shoot that combo either but it will shoot 168MK sierras very well varget 43grs/ gm210m primer / win case / 168MK
i also used IMR4350 had about equal results 1/2-3/4" @ 100yrds
