what does everyone who reloads seat there 22250 loads to? I have a tikka t2 in 22250 that im doing load work for with 55 gr nosler bt. I have only reloaded for a friends in the past and chased the lands there and it did well accuracy wise, speed was ok.

this tikka has a 21.25 inch barrel which is gonna cost me in the speed department. the mag has lots of room to seat to the lands which is what ive been doing, 20-40 thou off. using cfe 223 which according to nosler and hodgdon is one of the fastest powders for this bullet. I get a slight stiff bolt lift about 1 grain before book max at 20 and 40 thou off the lands. no other pressure signs but that's enough for me. 3600 fps will be tough to achieve using this powder, the slightly stiff bolt lift load does right at 3600. the accuracy seems to be there.

the other powders I have to try is varget and h4895. I figured id try cfe223 first as its supposed to be faster and I have lots.

now the big question is do I keep fooling around out near the lands or seat to book spec and jump a mile possibly picking up some fps while still shooting well. I could burn $$$ figuring this out but id rather hear some opinions on some people with experience with the 22250. thanks.
 
Our opinions won't mean anything. Only your gun knows the best COL for your loads and gun, and only experimentation will explain it to you. Sorry, but knowing my rifle and load likes .025 jump is useless to you. Unless, of course, it isn't. But you'll never know until you've tried them all. So the answer is, "keep fooling around."
 
I guess what im asking has someone tried the book oal vs near the lands? how does it compare speed wise. id really like to be at 3600 plus with this 22250. I have a tikka 223, it will do 3290 with a 55 and 3390 with a 50 gr. the tikka 223 mag gives you no options but seating to col. if the shorter barrel 22250s are not at least 300 fps more than a 223 with the same barrel length then I don't seen the point.
 
I have a t3 22-250 and have used the same bullets. I started out near the lands. Then I was trying 40 grain BT's which wouldn't reach very close to the lands and noticed better accuracy. I then tried pushing the 55's in further and there was no change in accuracy that I could discern.
 
"Book" OAL is nonsense (except for your own log book.

Stiff bolt lift means you are at or over proof pressure. Back off a grain so the bolt has no resistance.

CFE is a good powder. So is Varget and even 4895.

I would do my load development at 20 thou off the lands. Work up in 0.3 gr increments to find what the rifle likes.
 
I have a 22/250 Rem 700 VSF that shoots best .0010 off the lands. it just loves H 380 and the Berger 52 gr . gets me .3 to .4 groups at 100 yds. Vel is a tad more than 3600 ft/sec.

I don't understand your thinking that COL is vital to velocity. It's just not nearly as important to velocity as several other variables in the reloading process. If a load doesn't get "3600 plus" at one COL, it is not likely to change much at another COL. Look to other factors for velocity. COL does seem to be highly correlated with accuracy, but, other than making sure you don't jam a bullet in a load that wasn't worked up with the same kind of land contact, ignore what it does to your velocity and concentrate on its effects on feeding and accuracy. My first choice would be to change powders.
