I use IMR 4064 in my 22-250 now, but Have to run more patches down the barrel to clean it then normal. What are your thoughts on Varget or H-380 loads??

Looking at the Nosler 5th edition, for 40gr ballistic tip the most accurate powder is listed as Varget at the starting load of 34grs, win brass wlr primer.
The 50 55 and 60 grs all show H380 as the most accurate powder with the same brass primer combo.
The 50gr H380 starts at 37grs
" 55gr "" '' '' 35.5grs
"" 60gr "" "" "" 34.5grs

So far, for me, H-380 has proven the better of the two powders...

Can't go wrong with either powder in my opinion.
When it comes to metering the H380
is the one to pick.
I love Varget, but throwing it can be
problematic at times.

I have had by far the best luck with H4895 in my 22-250. I use 34.5grs. with a 50gr. VMax.

For me, I like to stick with a propellant that gives me a balance highest velocity, and highest load density w/o going compressed per the particular application. Also, should you go with H380 you might work up some loads using magnum primers. I always get better accuracy using them.
For some rounds i.e. .223, this almost means ball powder, and you get superior metering as a bonus if that matters.
H380 got its name because it is the charge (added a zero) B. Hodgdon used in his 22-250 getting one hole groups with 52 grain bullets and 38 grains of H380.

Been using IMR 4064 and H-Varget for .22-250.
H-Varget is easier to work with in powder drop device.
G&A mag had article on .22-250, they had a bunch of loads at 3800-3850fps with 55gr bullets. Article is probably on their website.
I went with 35gr of H-Varget, 50gr V-max, Nosler brass, and CCI large rifle primer. Shoots like the factory Hornady. I haven't run them through the chrony yet.

I was in your boat, I ran IMR 4064 exclusively in my 22.250 up until 2 years ago. It shot good in my opinion. For some reason, I decided to try some
H-380. Wow, I didn't even think I could shoot that good. It meters well and I still use it. I have often thought about trying to work up some loads for Varget, as I use it in my .308 and 7-08. I just haven't gotten around to it. My advice is try both. Why not? I have been amazed by the inprovement over what I thought was good previously.

"...Have to run more patches..." Run a solvent soaked patch through and leave it there for 20 minutes or so. You need to give the solvent time to work.

20 minutes?! Who has that time?
Stay with whatever powder is accurate. Then, go to the Sinclair website:
