22-250ai ?

[bozo699]

Fireforming with a max load is fine and the barrel should be chambered for a crush fit on virgin brass. If not, you'll have to load the bullets a little long so they jam, holding the case head securely against the bolt face. As far as measuring neck tension, a good 1" micrometer is all that is needed. Be sure to check the calibration of the micrometer prior to measuring the neck diameter. If you haven't purchased dies yet? I would recommend a Redding Type S bushing neck die set and purchase several bushings in .001" increments so you can keep the neck tension right as the brass work hardens. Good luck on the project !

Mike,
Not contradicting you but with the AI chambering enough of the shoulder touches you don't have to jam the bullets to keep the head against the case, if this was say a 6br to Dasher then you would need to jam the bullet or create a false shoulder or something, I suppose it wouldn't hurt anything by jamming the bullet.

I have a 22-250AI 8 twist and a 12 twist try the 53gr Amax in your 12 twist Im still working up a load in the 12 twist but so far the 53gr Vmax is working pretty good this is the first group with the 53 Vmax

thats a good start there how much more do you need to improve that? what is the load

The load is 35.5 grs Varget 3644 fps avrg I think I can get a little more velocity that load was almost the max for a standard 22-250 but not bad for a fire forming load

Rich,
This is not a bad group at all period, but if this was a fireforming group and if it is repeatable it is excellent so excellent in fact I wouldn't waste one shot fireforming at paper or for no reason, I would be killing GH's while fireforming, obviously a well put together rifle and you have done a good job tuning your fireform load, I hope your full house loads are as accurate, your rifle will be a blast while it lasts.

so when trying for a good tension what amount am i looking for?

I start at .002.....cause you gotta start some where..... ;D

Calib,
For fireforming you are going to want plenty of tension, a factory f/l or neck die will give you enough if you have a bushing die I would shoot for around .004-.005 tension, after fireforming if you have bushing dies, I would shoot for about .002 and play from there, if there going to be fed from a Magazine I wouldn't go less then that and that may not be enough, as recoil can push the bullets back into the case and cause EXTREME pressure spikes, you will have to check for problems there. If it will be a single shot you can get by with even less, some powders like less tension and some like more, that is the beauty of bushing dies, you can experiment, hope this helps some.

I love seeing groups like this out of a varmint rifle in the morning, it makes for a wonderful day. I think you ought to take that to a local match, i think you could come away with some of that stuff uncle sam prints off in your pocket.

i have seen some bullets in the 60 to 65 grain area does anyone shoot or have any experience with these i seen a couple with real good bc's in the bullet database on the home page here

Thanks, this load is very repetable but even if I can't get much more velocity on it I will be very happy with this load. I have a few AI's a couple of 223's and a 8 twist 22-250AI and am in the process of building another 8 twist 22-250AI on a Stiller action and Kreiger barrel. BTW this was shot with a re chambered factory Savage LRPV

I would think a 60 grain flat base would be the limit for a 1 in 12. The bullet maker should be able to tell you.

That is simply amazing!

Calib, the BC on the 53 grain Vmax is .290. It is probably going to be the best BC that will stabilize in a 1/12 twist barrel. You should be able to push it nearly as fast as a 50 grain so if your gun likes them, I don't see it getting any better.

Rich, nice shooting. My lrpv 22-250 will shoot like that with n-140 and 50 Vmax. I haven't ran out of loaded rounds yet so I haven't tried the 53 yet. The barrel is starting to foul worse than it used to so I'm hoping it holds on a little longer as I'm not ready to give it up yet.

 

[calib]

well good thing i have some of those. i will be trying those and the 55 grn noslers. hopefully out of those two i can get a good load going that will give me accuracy, speed and some range.

anyone load any of the hornady's (53grain hp match)

 

[calib]

woops i meen i have some of the 53 grain hp match bullets not the 53 grain v max's i may have to try to find some of those

 

[trentalan34]

If those are the 53 gr Sierra SMK's, give them a try. They shoot really well in a 22-250 ai and a 22-250 that I have.

 

[calib]

I ordered some v max's last night and a neck reamer for my 6-285 project

 

[calib]

it is gonnabe fun breaking in these two rifles and figuring out a load for the both of them. the 53 grain v max's sound like they will do ok in the 22 250 ai, but i have some 55 grain noslers that i would like to see doing well out of the cartridge also.

 

[calib]

rich
i got those 53 gr v max's today in the mail hows your loads coming on that rifle?

 

[rich44]

I really haven't done any more load work, real work is taking up all my time right now. Plus I have two new rifles being built/waiting on parts, a 20-250 and another 22-250AI 8 twist (something that doesn't weigh 14 lbs) more suited to coyote hunting. I also have a 6-284 that I just started working up loads for in the fall but haven't had any real success with that one.
Keep us posted on your results

 

[calib]

ill be interested in hearing how the 1:8 twist 22 250ai goes everyone has been telling me i should have gone that route. maybe down the road more i will.

what twist did you go on your 6-284?
what have you done for loads soo far? i have one that ill be puting together once i get the barrel

 

[rich44]

my 6-284 is a 8 twist 30" Benchmark on a Savage target action. I have only tried the 105 Amax I put together a 20br at the same time and kinda lost interest in it the 20br is just to much fun. the only two powders I have tried are H4350 and H4831sc they both work very good in my 6.5-284
