    NO That is a great load with the RIOs. Just load them and keep busting targets.

    The Rio's are larger in diameter. When you switch be prepared to shoot the hulls until they wear out with the Rio primers.

    What Ajax, said. Rio's work fine. Similar to Fed 209's in my experience. But, the hulls are no good for anything but Rio's afterwards. So, reload often and enjoy.

    <blockquote><I>"Check the rio website, they have some data. rios are large and a pretty hot primer.</I></blockquote> I quit using Rio primers several years ago when Rio changed the brisance of the primer without warning and caught the powder companies and wad makers by surprise. I've talked with representatives of both industries since then and they each indicated that there's no way to tell where Rio primers fit now on the "hotness" scale without testing them.

    I wonder if Bruce used Rio's in the H&R he was trying to blow up?

    We may have stumbled on the key.

    Rio primers do NOT go willingly into Gun Club hulls. Rios are metric and several thousandths of an inch larger in diameter than the largest "American" primer.

    Rio primers are intended to fit Rio hulls and are a force fit in every other hull you'll encounter.

    You will have less trouble (not no trouble) seating Rios in Remingtons if you're using a MEC or a LEE loader than a PW.

    I probably spent as much money replacing Browning firing pins that got burned by punching Rio primers as I saved by switching to Rio primers in the first place.

    Hope your firing pins survive! (hard as a rock)

    I have used nothing but Rio primers the last 3 yrs and have had no problems with loads at all. They due make the hulls unusable for any other primer tho as stated by several others.

    I have never had firing pin problems using RIO Primers in any gun I have owned,
    Brownings, Ljutics, K-80s,Caesar Guerini, Blaser, Seitz, Alferman, 1100s, 870s, 3200s.

    Have used more than 50,000 of them around $98.00 per 5,000

    Now Fiochi's is a different story, mis fires, punching holes in primers.
