I am getting desprate trying to find a very accurate load for my new win 22-250 coyote, its got about 75 rds through it and I can't seem to get a sub 1 1/2 group at 100yds I tried varget, RL15, with hornady vmax and rem sp, 55 gr bullets and played with the seating some. at around 3600fps. It shoots new win 45 gr jhp better thease are going around 3800-3900 fps, I also have the med heavy barel. thanks for any help,

My 700 likes the white-box win too. I made a huge mistake when I first started reloading for 22-250. I thought that once fired shells didn't need to have the cases trimmed back. If you're doing the same consider yourself lucky to get 1.5" and lucky that you still have a gun in one piece. The 22-250 is generally a pretty darn forgiving reloaders cartridge so I don't know what it could be besides something in case prep. I still haven't had luck with 60gr partitions, but that's likely because I've only tried one powder and the partitions are probably just too long for my guns 1-14" twist. There are alot of more knowledgeable guys on here, they'll be able to point out other problem areas with the 22-250. Good luck

In the last 10 years,I've had the best luck with IMR4064,in the 22-250.Also,the Remington bullets are not going to group much better than what you have gotten!!!!Try Hornady 55 V max and see what happens?

35 Gr of RL-15 with your 55 gr bullets. This is a pretty light pressure load, but be careful.

I would start with them seated .010" off of the lands.

Hard to beet 38gr of H380 behind a 55gr bullet! I've got 2 Rem 22-250's & that's the best load in both.

Are you cleaning the barrel often? a new barrel can be rough and hold copper quickly

Fishead when you say 22-250 coyote are you talking about a
winchester coyote? I have the coyote lite in 22-250 and it loves 50-55grn
and varget. It shoots the Barnes 53 trx real well but they are a little$$$

You might try polishing the bore well with J-B Paste after a good cleaning, and also 45 or 50 grain bullets might shoot better than 55 grain or heavier slugs in that 1/14" twist......
