Do you have a pic of the .22-250 cartridge? I'd like to get an idea how much powder you're putting behind it
Here's one of my .22-250Rem/55Blitz loads as done up for my Striker. On the left is a .223Rem/50Blitz, then the .22-250, the a ruler, and finally a .243Win 87gr factory.
I consider the .22-250 and the .243 to be in the same rifle case class although the .243 is definitely larger. I find with medium and heavier bullets in this case size class Varget works very well. For an extruded powder, it meters like water and its temperature stability affords great consistency. I'm not going to give you charge weights, because those should be worked up by yourself for each particular rifle and bullet seating depth. You will note I use moly coated bullets exclusively in high velocity rifles. Moly coating allows 1 to 2 grain heavier charges and minutely higher velocities.
This is a group I shot with my .22-250Rem Striker 14" pistol at 100 yards during barrel break in. It's actually two groups of five with a cleaning in between. .22-250 has been very, very good to me.

What are those groups in MOA- if it works that way?
Congratulations that's some Fantastic Marksmenship!
Thanks for your kind words, but I know a lot of people who can shoot much better than I can. Minute of Angle (or MOA) works out to be a little bit less than an inch at 100 yards, but by convention it's considered to be one inch at 100 yards, two inches at 200 yards, three inches at 300 yards and so on. You also have to figure out a way to measure your groups so as to get consistent results. Groups are, by convention, measured center-to-center. To get a group size, I use a digital vernier caliper to measure the distance between the furthest apart edges of the most widely spread two shots and then subtract from that measurement the diameter of the bullet being fired. It's also convention that if the shooter sees the reticle moving off the aiming point at the instant the shot breaks, he or she may call a flyer to the clock position they saw the motion. If the hit was out where indicated, it can be treated as a called flyer and discarded (but not in competition). The groups I have posted have all been sub-minute, some have been sub-half-minute.
I shoot precision rifles generally off the bench at 3/4" black stick-on dots on heavy white paper to get a fine aiming point sharply in contrast to the background (Aim small; miss small ) The dots are, as you can see slightly smaller than dimes. Benchrest testing of firearm/ammunition combinations just shows you how well they work under relatively stable circumstances. Shooting under actual field conditions is way different!

That certainly looks like a good cartridge to use when you want to reach out and touch something.
Dangit, now you've really piqued my interest into a Remington 700. Wish I could get back into shooting, but I do not have the money to replace my target .22 rifle or to keep up with high power ammunition costs. I should have grabbed a Winchester 52 from my dad when I was visiting him last year.

Well I went into the store with a Marlin .17 in mind
however, when I saw this savage I couldent resist
My dad gave me a Bushnell Sport View scope
I sighted it in at 50 yards and was getting .5" groups
I plan to take it to the range tommorow and get it out to 100
