Which bullet out of those for hunting in 50 or 55gr has the highest bc.

Heaps of people use Nosler bt's but are there better choices....v-max etc.

I also here nothing of sierra blitz kings ??

I use in my 22-250 Serria 55gr h.p. bullets and that bullets blows the critters up.

My two cents------
BC="Ballistic Coefficient" is only one of many components that you should consider for a hunting round. By itself, it makes very little difference except maybe a extreme range.

You didn't say what type of game your after but,
each hunting situation has it's own needs. A round like a 22-250, that actually can have many different targets makes the selection more difficult. For p-dogs a light skinned, almost exploding, bullet works well, for coyotes you might want a slightly heavier constructed bullet, and for deer you might want the use a heavily constructed bullet like a Partition. However, each manufacturer call each type by a different name so research becomes important.
Hence your posting.

Of course now that I've said all that, I reviewed your post again, and noticed that your from the land down-under. If you want to say what you plan to shoot at, I might be able to recommend better?

My 2 cents
55gn soft nose hornady's for foxes. Seem to have the right mix of expansion for the summer pelts and penetration for the winter pelts.

I think 52gn .224 bullets have the best BC. But with the feild accuracy I get with the above I don't see any reason to chase down the 'perfect' bullet.

PC ,
The 50 gn Nosler BT is crash hot on rabbits , roos , foxes etc. Don't recall trying the 55 Nosler but it does have slightly higher BC (.267) and should perform similarly .Some 14 inch twist barrels won't stabilise them though .
I have found the Noslers more to my liking than V Maxes .Don't seem to get the same number of unexplained flyers .Also found that V Maxes are very quiet and sometimes difficult to know whether you've made a chest hit on roos .
The 52gn Sierra Matchking is a good accurate bullet and very effective on above game . BC isn't great though .

Big Dog, I use my 22/250 mainley for foxes, crows, rabbits etc. It's a varmint gun so I don't hunt pigs with it etc.

I think I will try the 50 gr Nosler BT's when I get through the last of my factory stuff. Originally I was interested in the 60 gr V-Max.....any one use this ??

Sorry that I can't answer your question. I think that bc is a function of velocity, so I don't worry about that directly when developing loads. First, I select bullets that will do the job for the game I plan on hunting. I've been doing a lot of testing over the last two months on four .22 caliber rifles I want to use for coyote hunting. One is a 22-250. Of the six bullets I tested in it, the most accurate is the Sierra 55gr HPBT. I tested some Bergers, Noslers, and Hornady's in the 50 to 60 grain range. I only shoot 3 shot groups for load developing. This load that turned out to be the smallest was with Benchmark powder and Federal Match primers with bullets .010" off the lands. That group measured 1/4" ctc. I got a very good group with the Berger 60gr varmint bullet with Varget, but that group was at the lowest velocity using Varget. It measured 3/8".
I guess my approach is to use the best bullets for the game, and find the one that shoots best in my rifle, not worrying about bc.

Pretty sure there is a statement on the 60gn V Max box about requiring a 12 inch twist . Not sure what your CZ has ?
As far as BC goes I've not found anything (commonly available in Oz) in 55gn or less with better than the .267 of the 55 Nosler BT . Have a feeling that Sierra have a 55 gn spitzer with the same BC . Check their website .

Published BC's are suspect. It seems as if all of them are high as compared to actual tests.

As others have said I would just use what shoots and impacts best. A sharp meplat is the first thing to look for in a superior BC.

I tried the 55 Sierra's in a 1-14" Swift and the accuracy was iffy in an initial effort. I shoot the 50 gr Sierra BK in that rifle now and its all set. The 55's will stay in the drawer forever or until a 1-12" .224" comes along if ever.

I don't worry about BC much when developing loads either, but BC is only slightly influenced by velocity. BC = Weight/Form x Diameter^2

Hornady VMAX BC's:

40 gr, .200
50 gr, .242
55 gr, .255

Nosler BT BC's

40 gr .221
50 gr .238
55 gr .267


The Noslers have a slight edge as published and I believe their info correst. I find the BT's to be a bit more accurate in the main as well. They have a better base design in regards to drag reduction IMO.

Hope this helps.

Dan,
Thanks!!! Appreciate the info.

Either the Nosler's or V-Max's should work well on your intended target. I shoot both in my 22-250
