One post 'sort of' answered my question but I need to refine things a bit. I am thinking about a 22-250 or .223 with a 1 - 7 twist barrel.

The lightest bullet I use now is a 52 grain Speer Match with most loads a variety of 55 grainers out of a 1 - 14 twist barrel on a sporter weight rifle.

Will the 1 - 7 barrel give me problems with the above weights re: accuracy or over-spinning and can they be mitigated by reducing loads, etc.?

Of course I want the quick twist so I can shoot heavy bullets but it would be nice to have flexibility to use lighter ones occasionally.

Thanks

My experiance has been faster twist favors heavy bullets. The light ones seem to shoot poorly. I've seen many posts by people having good groups with them and I had a great group with some 52 gr SMK's in my 1 in 7. I never worked up a load for it though and its gone to a better home so I can't follow up on it, may have just been a fluke. I've found in my two 1 in 9 .223's that 60 - 70 gr bullets perform the best. The 1 in 7 performed well with 75, 80, and 90gr.

It may be I'm not seating my bullets a straight as they could be and the shorter ones show greater variation. I don't bother with light bullets anymore though.
 
Unless you eventually want to try 90gn match bullets you don't need a 7 twist.

The biggest question you need to think about is what will this rifle primarily do? If its a rig you plan take to 1000yrds then a 7 or 8 twist is a must. If it will be a gopher blaster and part time range toy to about 500yrds then a 9 twist should suit your needs very well.

Personally a 22-250 with a 7 twist for 90gn berger VLD's would be AWESOME for a LR target and varmint rifle.
 
if your making a 1000 yard 22-250,i guess theres some brass issues to deal with that you cant and its better to go to a 22-250ai.PM a guy named Dale J or just bring up reg /ai 22-250,someone smarter than me will let ya know

something to do with the sloping brass,causes handloads to be ....changing.


i sort of just had this prob with ...you guessed it a 300H&H.Dont get me wrong i love the 22-250,but mines a coyote rifle ,factory,and not a target rifle. Still a 90 gr match king coming from a 22 cal would be cool.
 
As said above, depends on your desired usage.

1:7 may or may not overspin a 52 gr - probably not but why take a chance? Me, I wouldn't even bother trying to shoot anything lighter than a 60 and probably mostly 70+ out of that twist. Reduced loads? mmmm maybe. Might be you want to stick to a 1:9 if you're doing lots of varminting with lighter bullets + some range time at medium-long distance. Heck, 69gr Sierra MK's (or similar) out of a 1:9 will take you to 1000yds all day long.

Not directly related, but a 22-250 is known for quickly lengthening brass + lots of trimming, that's why guys mention 22-250 AI - the squarer shoulder greatly reduces the brass flow.

Barrel life will (should be, anyways) THOUSANDS of rounds more than a 22-250. Which may or may not matter to you, just putting it out there.
