I followed the OCW for the 58 V-max with IMR 8208 and found a sweet spot for this rifle. I turned down the gas port on the Syrac and needed to open to 10 clicks to get the rifle to eject and hold the bolt open with a mild sighting in load. Once I found the sweet spot I loaded up a few more at that charge and closed it a two clicks and still had good function and shot the group below.
42.2 grains of IMR 8208XBR seated to 2.600 OAL - These were over 3700fps in my bolt rifle but I have not chronoed them yet out of the R25. I would say that they will do for coyotes. I will take 1/2 MOA everyday all day. Moving up to heavier bullets next.
I got the .308 bore sighted and centered on paper with some FMJ Nato ammo. going to try some 168 SMK's with Varget in that one.

very nice, Dawgdad. Keep us posted. Can't wait to see the hunting results. Do you plan to hunt deer with it? If so, what bullet?

We are a slug gun state in Illinois so I will only be taking coyotes with it for now.
If I can get an 80-95 grain match bullet to shoot this good in it I might use it in some 300-600 yard prone matches too.

The .243 I'm shooting is 1:9. Its a Rem 700 and I measured it with a cleaning rod several times. I believe the heavier/longer .243 bullets need the 1:9. Is that why you are only looking for 80-90 grain bullets for longrange target shooting. Would you use heavier bullets if you had a faster twist? I just bought some 90gr E-Tips (all copper) that said they needed 1:9.

Thanks for the explanation, Aloys. You must be a happy man.

Slim. I'd use 105's if I had the correct twist. Next barrel will have that.

I have seen where faster twist barrels don't shoot lighter bullets as well, particularly in crosswind situations.

It really depends on the barrel and bullet combination in my experience. I have a 7 twist 22 barrel that hammers everything from a 45 grain to an 80 grain. Also have a 1:9 that only likes 55's.
I will try some 85-95 weights in the 1:10 but it will be bearing surface/ profile dependent and velocity dependent on whether or not I can make them consistently stable for long range use.

I just loaded up some 90gr E-Tips with a .403 BC. They say it needs a 1:9. I'll let you know how they do.
