    Barrel preheating (is it a thing)

    if your point of impact is shifting as the barrel heats up, you have a poorly bedded rifle (stock issues) or a barrel with internal stresses. This occurs frequently on cheap hunting rifles with a pencil contour barrel. Rifles with a properly bedded stock and a quality barrel—Bartlein, Brux...

    New Guy from Ky

    Welcome. I live in kentucky. Unfortunately, Ky has nothing for LR. Tennessee and Indiana offer good ranges for learning and competition. Do your research and get a rifle/scope combination that will take you to the distance you’re interested in. Don’t wait to buy the best. Enter...

    How long do you wait between shots

    For a well-built rifle with quality barrel, action, trigger etc, the time between shots is based on getting the shooter ready not the rifle. consistency is key. Shoulder pressure, cheek pressure, sight alignment, breathing with a NRP, and trigger pull have to be exactly the same shot-to-shot...

    Area 419 ZERO Press (Black Edition 1 of 25)

    Like Keith in the video, I have wood floors in my reloading room. It does help a bit.

    Area 419 ZERO Press (Black Edition 1 of 25)

    Here’s a tip. If you’re running a lab balance with granite slab, the zero foam packing cushion with “zero” cut out makes a very good vibration damper under the scale.

    Failure to Fire / Light Strikes when reloading .223 on a Dillon 550

    Yes. measure your primer height including the protruding anvil (a) and measure the primer pocket depth (b) of your cases. Subtract a from b. This tells you the distance below the casehead to seat the primer for no crush. You can experiment with the level of crush that work best for your...

    .308 Win long range bullet selection?

    They still make the bullet but they’re hard to find. Sold out everywhere. You‘re probably thinking about Berger’s 200.20X line of ammo that was discontinued.

    Recoil Management

    Interesting research. I did some research regarding bullet time in barrel from sear break to barrel exit pertaining to shooter follow-through. But nothing pertaining to tripod wobble or unstable shooting platform. FWIW, Attached is file.

    Shoulder bump inconsistency

    The numbers you are giving are obviously from a comparator. Not true base-to-datum numbers. New Lapua 308 win cases are all within SAAMI cartridge spec which is 1.627” min base to shoulder datum.

    Shoulder bump inconsistency

    I like nn8734‘s approach and I have a similar method. The Forster HS gauge set is nice but Forster stopped making them. I use a go gauge and then use aluminum foil on end with a smidge of paste to find exact headspace (reg foil is about .0004 - .0006” and ” and heavy foil is right at .0008”)...

    Bullet runout worse by using an expander mandrel?

    Nalye: we are talking about thousandths of an inch right, not millimeter? I know you guys in Germany use the metric system. 100/1000 of a MM translates to about .004 inches which is in the acceptable runout range.

    Bullet runout worse by using an expander mandrel?

    A tenth of an inch runout indicates you are doing something wrong. What brass are you using? make sure the expander die is not coming down too far and hitting the case mouth. As Rhed said, use a dry lube inside the neck.

    Small vs large rifle primers

    I had used standard 308win Lapua brass for years and just last year I bought 600 cases of Lapua Palma brass (SRP) so my experience is limited. I have not noticed any gain in precision or lower velocity SDs with the Palma brass. My results with the standard LRP lapua brass were very good so I...

    Patches clean but bore still smooth black

    did you read the post? I said “the 710 and CDL are factory rifles with generous factory chambers and you don’t need to scrub all the carbon out to avoid pressure issues. you can go a long time with just normal cleaning before the carbon causes any issues.”

    Patches clean but bore still smooth black

    It’s carbon and you will need to used an abrasive like Iosso or JBs bore past (not the bore bright) to get it all out. But the 710 and CDL are factory rifles with generous factory chambers and you don’t need to scrub all the carbon out to avoid pressure issues. you can go a long time with just...

    Which brands have the most insufferable fandom? Geissele? BCM? Noveske? Colt? Sig?

    Forster Co-ax. the insufferable cult members using this red toy claim that bullets self-correct for wind in flight if seated in this thing.

    Agree. but a lot of shooters have picked up a used V3 and supplemented it with the Ingenuity Precision powder trickler (fast and accurate)

    Shoulder bump questions

    This is good advice. As with most advice to new reloaders, the answer is “it depends.” If you’re only banging steel or target shooting with your friends , then an occasional stiff bolt or hard-to-chamber round is no big deal. You can push the limit and wait til case dimensions reach the...
