Thread: 22-250, H380... primer question

    Default 22-250, H380... primer question

    Most of the recipes for using H380 in 22-250 loads calls for a magnum primer...I worked up a load of 38grs. H380 for a 53gr. bullet..it shot to .5, almost a clover leaf, I used a large rifle primer...I was wondering what difference a magnum primer would make, more powder burn, faster..?

    Magnum primers are more zippy, but often have more variation and thus make less accurate loads.

    Here are some loads I tried in my Howa 22-250, some with H-380

    3 of us have used a near exact load of H380 and 210M primer with equally wonderful results and 40 vmax

    Sounds like the load that I used for yotes in NM back in the 80s out of a 788 with a 4-12 scope. I wish I had that gun back. It was sweet and accurate...... I wish I had the eye coordination back too....

    Oneriver, I shoot a 55gr NBT in front of 41 grains of H380 with Federal 210 LR primers. My chrony'd avr velocity is 3739 fps for five shots. Best group is .209 at a 100 yards. That's thru a Remington 700 Varmint with a 26" Hart SB#17 Kreiger HV barrel. I've never tryed the magnum primers on this load and it's safe to say I probably won't. LOL!!

    Thnx for the replies..interesting info..I'm really having a blast working up loads for this rifle, my first CF varmint rifle, a Savage Predator 110 with a 1 in 12 twist...I have a Leopold scope 4.5x12..the gun out shoots the scope so I'll sell it and I'm thinking about a Nikcon with the BDC reticle (circles) ...I looked through one at the store the other day and thought it might take some getting use to...my other choice is the leupold which having the cross hair reticle might be more useful for smaller critters plus you have the hash marks for wind-age...any thoughts or suggestions...?

    Bruce Hodgdon named H380 powder from his favorite load of 38.0 grains in his 22-250 Varminter. I have found what FloatPilot says to be quite true. Magnum primers bring erratic ignition and less accuracy in loads of lower volume (such as the 250 Savage case). Generally we use magnum primers with ball powder, not this time. This is a true quarter mile varminter cartridge.
    Is there nothing so sacred on this earth that you aren't willing to kill or die for?

    Oneriver, regarding scopes, I have three varmint rifles that I use on a regular basis (every day, I'm retired and my place is very isolated and surrounded by timber company property). I have a .223 Savage 12 with a Burris 4x16 w/BDC reticle, a customized Savage 12 in 22-240 Wby Mag with a Burris 6.5x20 fine crosshair and a Remington 700 Varmint 22-250 with a Leupold 8.5x25 fine crosshair. On the Leupold I had them make me a custom BDC dial to fit on my elevation adjustment mechanism.
    To make the dial I had to send them the caliber I was shooting, the bullet type, bullet bc, fps, avr temp of where I live, and avr elevation plus wether you want a 100 yard or 200 yard sight in. They send you a dial that goes in 10 yard increments out to 1200 yards (1400 on my 270 Wby Mag). This dial only fits on a TARGET turrent plus I only did one for elevation not windage.
    In terms of best to worst for drilling things at long distance it's the Leupold with BDC dial, then the Burris BDC reticle and then the plain Burris which I now hardly shoot. The dial from Leupold is amazing. If you know the distance to your target just dial in the distance, put the crosshairs on the target, pull the trigger and bam, you're eating crow gumbo!!Yum, yum.
    Hope that helps ya.
