    Range Report 26 Nosler

    PTG has the reamer print now. It's a 404 Jeffery/RUM shortened to 2.59 with a 70 degree shoulder. Nice size cartridge. I used QuickDesign to make variants from .243 to .458. Very cool ballistics on every caliber. 243 is a little ridiculous. 257 is just weird 264 is a 26 Nosler 277 would be...

    Range Report Which 7mm

    Neck down a 375 Ruger, go with a 7 Dakota, or neck up a 26 Nosler. Pretty much the same think except for some minor and rim dimensions.

    Magnetospeed v2

    Yes I use it on a AR-15 form factor. Hand guard does not get in the way.

    Gonna build a 338 - 338 Edge or 338 RUM

    I've been busy with work since the last update. My work season is most intense from August to October but this year got extended through December. All the parts are off to the gun smith. I changed the barrel profile and brand to a Benchmark Heavy Palma. It's longer and fits the barrel channel...

    Trim new brass before neck turning??

    I use a Forster Original with neck turning, indexes off the base same as sizing. This is my procedure: FL size with an over sized expander so the ID is the same size as bullet diameter. Turn, for BR chambers to chamber spec, for standard chambers, skim/truing. Neck size. Trim to minimum length...

    208 AMAX in 300 weatherby

    I don't feel comfortable quoting max loads outside of published manuals. I'm sure that a load for IMR4350 can be found. Regarding freebore: as I understand it, the long freebore is/was part of Roy Weatherby's philosophy. Give the bullet a running start results in reduce pressures and increased...

    208 AMAX in 300 weatherby

    Eight_Ring, When I plug what is available into QL, predictions are with 1% of your published actual for all loads. EI: Your actual 66grns of H4350 was 2666 my predicted was 2643 Classic/standard/conservative would say to use a slower powder than H4350, it seems to work. FWIW: My 300WSM load...

    Magnetospeed use with forward brake? Anyone out there had issues?

    I have used my V2 plenty with radial pattern brakes. Not with the holes facing forward but 'normal'. There are no issues AFAIK.

    RL-17 to fast?

    There are of course more 'normal' powders but if it's what you have... Alliant web site Alliant Powder - Reloader's Guide Has Speer 180 BTSP listed.

    what kind of chronograph are you all using?

    That's not my experience. Perhaps a little creativity but it will work just fine. Now an S&W 500 Revolver, that came close to being a bad idea.

    Range Report Riddle me this...

    I had to adjust the BC in the ExBal software I use. I tried adjusting for velocity errors first but that didn't fix it. I think BC can go up with fps.

    Few questions on QuickLoad

    I guess I'm an 'advanced' user. For me QL is a great tool. Smart reloading dictates using multiple data sources. I add QL to paper data and other data. Those that say it's a waste are trying to make the world into an image of them selves. Very boring if we where all the same. If I put the...

    260 rem gas gun velocity

    It seems fine to me. You can make 1000 yards at Sea Level. Fast is not accurate. IIWM I'd stay with accurate. I run my bolt gun at 2750 with 140s. 1000 yards on paper first shot.
