    Anyone know anything about this new bullet from Sierra? Supposedly .6+ BC.

    https://www.midwayusa.com/product/1...-224-diameter-95-grain-hollow-point-boat-tail

    I called Sierra tech support to get specs but they said they didn't have any info available. I'm assuming it needs a 7 twist but what I really want to know is OAL and ogive to tip compared to the 90gr to see if it will work for 224 Valkyrie at mag length. I guess I'll order a box to find out for myself.
     
    I won't need to do anything if they can hold together. I'll need to know their actual length to get minimum stabilizing rpms figured out too.

    If someone could run these at just under 3,200 FPS it would seem to be the best ballistics vs. recoil load for a PRS type match.

    What cartridge would get these to 3,200 FPS most efficiently? My first guesses would be 22 Dasher or 22x47 Lapua.

    What kind of barrel life could be expected with these fired at 3,200 FPS? If it is much less than 2,000 rounds then it would not be worth doing for me.

    Both of those variants in 6 are ~2500 conservatively right? I would assume that necking it down could be cutting it close to your 2k mark but thats just hypothesizing.
     
    In curious if they'll be able to handle the rpms needed to stabilize them. There were plenty of guys blowing up the 90 Berger's trying to get good speed but enough rpm to stabilize them.

    Cool bullet!

    Hopefully Sierra is going to use a thicker jacket in these 95's.

    Already! Sierra fulfilled my prediction of more new heavy 22 cal bullets coming to market quicker than I anticipated.

    224V out bolt gun just became even more interesting.

     
    Guessing at some dimensions based off the 95 SMK product photo Quickload says at 60ksi chamber pressure and 26" barrel you can get a 2.8" OAL 22-250 Ackley close to 3150fps. A very long throated 223WSSM can almost push it to 3300. For a stability factor on a cool day at sea level you'll need about 1:6.25 twist propelling bullets to ~363,000 rpm. I think I'll let others speculate how long that barrel would last... lol.

    I'm not at all concerned about this. People have been running lighter bullets faster in 7 twists for years without blowing anything up except in extreme cases. I'd say if people were regularly blowing 90gr bergers up it was probably an issue with the bullets themselves and not the RPM required. I've shot thin jacketed 40gr varmint bullets out of 7 twists at much higher speeds with no issue so I just don't see how it would be an issue with this bullet which should probably be fine in a 7 twist at higher velocities.

    I'm interested in these for a 22-250 AI as well as 224 Valkyrie.


    Also Nosler is releasing a new 85gr RDF, I'm curious to see the stated BC on that one too.

    Fyi: 22 creedmoor and 90’s vld = 3250 fps with 40.5gr 4451 and 24” barrel, avoid straight 22-250 and aics mags due to sharp taper of the 250 cartridge, they nose dive in the mags and do not feed well, only other option to make speed limit is a 22-250 ai , but it takes fire forming and cuts an already short barrel life in half, havent burned out my 22cm barrel yet but expect around 1000rds with long strings of fire , this is a hot rod and bad to the bone

    It wouldn't be very smart to fire-form 1000 pieces of brass, for a barrel that will only go 2000 rounds. I.E you're an idiot if you cut your barrel life in half fire forming.

    Over the years I have learned all brass needs fire formed before starting load development.

    200 if it'll be a match gun and 100 if it's just for fun has worked for me.
     
    Hi,
    Has anyone done anymore work with these bullets lately? I am thinking of doing a barrel up for these or 90grn Berger's with the PRS 3200 FPS limit in mind .
    I am thinking 22-250AI as I already have the dies and a barrel I can fireform in mine is built as a varmint rifle on a Kelby single shot action how do you think the 22-250AI will feed out of magazines ? I know I could do a 22 Creedmoor but then I wonder if it has any real world advantages over the 22-250AI. what barrel length would be a safe bet to get a good load under the limit was thinking 23"
     
    Brass prep for the 22-250ai is no harder than any other cartridge to me and ive had 4 different 22-250ai with bdl and dbm setups and all have worked perfectly feeding. I think that anyone that says the 22-250ai dont feed well, has never had one before. I had a 22-243ai that fed perfectly also with a 7 twist. The 90 berger went poof every other shot though. It just plain didnt work. It was a bartlein barrel. Swithched to a lilja and that fixed the poof problem but then it wouldnt shoot them well enough for my liking. Now im gonna try a 7 twist 22-250ai for the 90 berger and 95 mk.

    Im getting 3170 out if a 22” barrel. 22 creedmoor for PRS matches. 1.7 mils at 500. Have not had a chance to test out further distances. AB calculator gives me 6.2 mils at 1000 in sub freezing temps.

    30degrees I had 6mil come up at 980, 3130fps in 22lrv.. could also see splash from misses and target indicator went off everytime I hit. My 9year old went 5-5 on a full ipsc, i was impressed with the little bullet for sure!!

    You don’t have to fire form with full power loads and bullets.

    When I shot long and short range benchrest, I used a wad of toilet paper over fast powder to fire form. Some used cream of wheat. Others had an old crappy barrel chambered with the same reamer to do all of their fire forming in.

    There are several ways to skin hat cat and save barrel life.
     
    22-250's biggest issue is the taper of the case and feeding in AI/AICS magazines. I shoot a 6mm-250 and can only put 6 rounds in a 10 round mag before they bind. In fact I had binding with 6 rounds this past winter. I disassembled all my mags, stretched the springs a bit, cleaned and then waxed the inside of the mags, and hope now I have the issue resolved (feeding 6 rounds in a 10 rounder).

    I'm considering rechambering for 6mm Creedmoor to get a straight case. The 6XC wildcat of the 22-250 also straightens the case. I can actually fireform my 6-250 loaded rounds into 6 Creedmoor as well.

    Going Ackley will fix the mag problems?

    How’d the 7 twist work with the 90 Berger and 95 smk in 22-250AI?
