I think I've found a good target round for my Ruger M77 MarkII 22-250. With a 50gr V-Max and 35.0gr Varget my last trip to the range netted 6 hits inside the 1" bulls-eye at 200yds. What really shocked me was that my 13-year-old granddaughter fired them....a total of 8 rounds at 200yds. The rest she fired at 100yd before going long. Folks,she had never shot this gun before that day. Just plinking with a 22 single shot at a 10yd indoor range. So,I guess I'll be loading for her,tweaking the rounds a bit. 6 out of 8 bulls-eyes just couldn't have been beginners luck,could it? Actually,I've taken her back to the range since with same loads,but it was just too windy to conclude anything. I'm really excited for her and hope to continue bringing her along. She really enjoyed the gun,as well.

No, I don't think it's beginners luck. If your granddaughter know the basics of shooting well and has good trigger control there's no reason why she couldn't shoot that 22-250 well even the first time. It's obvious someone taught he well, good for her!

I have a Ruger MKIII Target in .22-250. 15 years ago I worked up a load for it....36grs of Varget over a 55 gr V-Max. It will shoot all shots touching at 100 yards. I never looked for anything better.

The only training she got was at the range the day she shot. I showed her the right way to hold the gun(I shoot off sand bags),not to muscle it into position but to get it on target and let the sandbags do their job and gently squeeze trigger,and to shoot every round the exact same way. Prior to that day she had absolutely no training. I had her fire 7 or 8 rounds at 100yds where she got as good of groups as me,so I moved her to 200yds. Her dad does not shoot so I'm the only one she had to guide her(poor girl). I was also the one that took her to shoot the 22 at the indoor range where one of the owners spent about an hour with her,but,again,only a Little Champ 22 at 10yds. She's really excited and so am I to get her back out to the 200yd range. I'm going to stick with that round to see if it continues to perform. Besides,35gr is just .5 grain above minimum and I like that! Being a 22-250 I try to stay away from "hot" loads to spare the barrel a bit. I've been told they are notorious for burning out barrels. Very watchful of barrel temp,also,taking plenty of time between shots. This may make for a great partnership. She shoots well and I love reloading for accuracy. It's not unusual for me to spend 8 or 10 hours loading just 50 rounds. I have to load on the cheap so Winchester brass....very carefully prepared. If she keeps shooting like this I might spring for some higher-end brass. I buy the V-Max in 250 piece boxes and sort by weight. Every round she fired had a 50.0gr bullet. Having a hard time getting consistent coals,though,and I don't know why. I took the seating stem out,chucked it into my drill and polished the end (bumping off of olgiv) with 600,them 1000 grit,then 00 steel wool. Still,coals vary by as much as .005. Any idea what I'm not seeing? Standard 2-die RCBS kit.

Ruger, I like your low pressure approach and it seems to give good results in both your and your grand-daughter's hands.

.005" cartridge variation base to bullet tip is actually quite good. But this is not that important an indicator of round consistency, however base-to-ogive consistency is.

Suggest you measure and compare cartridge base-to-ogive measurements instead. You will likely find your reloads are more consistent than first appears. (The ogive is the curved front part of the bullet, a circular portion of which will upon firing be the first part to engage the leade/rifling.)

Here's how to determine this for yourself:

If you measure those V-max bullets out of the box, you'll see their lengths vary quite a lot. Even match bullets do. On the other hand, their base-to-ogive dimensions will be somewhat more consistent.

Observations: Twenty of my 50gr V-max bullets run .766" to .773" base-to-tip, in a fairly even distribution, with a 6 bullet cluster @ .768" - that's a 6 thou variation but a wide and even distribution. However those same twenty V-max run .372" to .381" base-to-ogive -a 9 thou variation- but with 14 of those clustered within 1 thou of each other, 12 @ .380" and 2 @ .381".

If you want to sort bullets, doing so by base-to-ogive length may be of benefit to you.

I'll generalize and say this reputable manufacturer maintains more consistent base-to-ogive dimensions in a bullet production run...and somewhat less consistent measurements base-to-tip. Similar observations can be made with Nosler's product, and I'll bet with other companies' as well. This is not a problem, so long as the resulting cartridges achieve the internal ballistics goal of consistent engraving...and still fit the magazine. ;)

If you google around, you should find something showing you how to measure base-to-ogive with what you have at hand. If you prefer, Hornady sells a convenient "bullet comparator" accessory for your caliper, that allows consistent bullet and cartridge length measurements.

I am using the same load as ColtPython.

The 22-250 is easy to load for. I have found the recipie for the 52 grain bullets in the Lyman manual's max load excellent for accuracy. If I do my part I can keep a 5 shot group at about 0.5 inches edge to edge @100 meters.
I have also found the 53 grain HPBT over 34.5 grains of N140 accurate as well.

Thanks everyone. My son and I took the rounds my granddaughter shot to the 200yd range today. Air was absolutely still. Let's just say we will not be letting my granddaughter look at our targets.
twofifty,I'm going to take your suggestion and find a way to measure from base to ogive. I've been beating my head against the wall chasing the coal. Thanks for the tip.

After searching Google for bullet base-to-ogive comparing tools I came across several posts that mentioned the John Buhay's (sold by Mark King) as being the best out there but could not find a seller. Any suggestions and/or opinions on this matter? A couple of other brands were also mentioned. Who uses what and how well do you like it? Any feedback at all most appreciated.

Ruger GP100 fan,
Don't underestimate how well someone can learn trigger control using a single shot 22 at any distance. Even dry firing will teach that.

BUT, from what your telling us your granddaughter seems to be a "natural" at shooting. Hey, keep taking her to the range and you never know, she might get a sponsor some day!

Did some more Googling and ended up calling Mark King. Seems the John Buhay model is no longer in production,but Mark's wife told me he makes an exact copy. He was away so I couldn't get much more info,other than asking her for a "ballpark" price on his unit. Said she thought it was around $160. Now,maybe if I was loading for a custom-built 1,000yd gun I'd consider it,but for a factory rifle and inexpensive brass,hoping someone can steer me to a much less pricey unit...say $50 or so. What's popular with you THR reloaders? I'm pretty sure I have a clear understanding of the advantages of sorting bullets this way instead of just weight and anxious to find out first-hand just how that affects my gun's (...and granddaughter's)capability. Can't really draw many conclusions without consistent rounds.

Take a look at this 6mmBR writeup on Hornady's bullet comparator.

http://www.6mmbr.com/catalog/item/1433308/977259.htm

btw, GP100, a lot of this measuring, weighting and sorting is 'busy work' when it comes to shooting recreationally at 100yds through a factory hunting rifle.

It might be more useful and more rewarding to get off the bags/rest and help her build position shooting skills like seated, off a post, lying prone, offhand. This would add variety for the kid, and would do more to build her in-the-field hunting skillset.

Thanks,twofifty. I'll give that some thought,but I don't think she has any interest in hunting and I haven't hunted for 30 some years and don't have any interest in starting. My main interest at the present is learning how to make the best ammo I can for this,my only rifle. She's only fired 20-25 rounds through the 22-250 so far and wants to improve on the 200yd paper. I'll mention the things you wrote and if she seems interested I'll try some of your ideas. I've just very recently gained access to 200yds and I'm not doing well there so I want to work on my benchrest skills too. But I really prefer reloading. I guess it gives my OCD a good workout:)
I realize that much of the effort I put into my reloads is lost on a factory rifle,but at this point I'm really excited about having a great shooter to fire my rounds and that my progress at the press speeds up a bit because of her. Who knows...the guy teaching me tells me that,yeah,the barrel will probably be shot somewhere around 3,000 rounds,then you buy a new barrel/rifle and start over looking for the perfect round again. I might want to get a better outfit by then and start reaching out to 4-600yds. The idea of being able to make good enough rounds that a good marksman (or marksgirl) could compete at those distances gets me excited. And,I want to learn all I can now so I'll be able to "hit the ground running" if such a situation comes along. On one trip to the range a guy next to me had just taken possession of his new 1,000 yd rifle and was shooting rounds through a chrono,working up loads for it. I can't even imagine shooting that far.

Sounds like you guys are having fun together and learning stuff.
You're a fortunate grandpa, and she a fortunate g-daughter.
