  1. Lee 429-200RF in 1894 Marlin 4 Star Review

    Posted by on Sep 26th 2018

    Bought 250 of these some months back to try on the Lee 429-200RF in 1894 Marlin 44. Could not get them on using Lee sizer either nose first or base first without ripping the check apart. Read the reply by Sage about polishing sizer. I chucked the sizer in Bridgeport collet and polished sizer chamfer lead-in surfaces with some HF assortment sand paper. First used 500 wrapped around a small dowel then 1200. Tried installing checks again with check entering sizer first and now works quite nicely. Just be sure to push check all the way flush with bullet base before pushing through sizer. Loaded some with 2400 today crimped in second groove using Lyman 4th edition 44mag rifle starting load for 210gn . Very pleased as no leading whatsoever.. Three rounds key holing at 25 yards on paper & smoked two fist size rocks without a miss out of my garden at 70-75 yards with open sights. Will buy these again next time I buy copper gators which are great.

  2. They work well on some plain base bullets 3 Star Review

    Posted by on Sep 4th 2018

    These work well on some plain base bullets but not at all on others. A couple of my molds have no problem putting them on in a Saeco lubrisizer but a couple rip the check apart. Those that work slide through with no problem and shoot well.

    I haven't played with them enough to see what the issue is but I would try a sample before buying 1000.

  4. works great 5 Star Review

    Works great on 230 grain .452 sized down to .429. Fewer keyhole shots and more accuracy, tighter groups at 25yards.

  5. 44 mag plain base gas check 3 Star Review

    Posted by on Jan 19th 2018

    These are not a cure-all for putting a gas check on plain base. It requires some adaptive work to your sizing die, and bullets must be cast into cold water to shrink them down. Big fat soft Bullets won’t go through with the gas check. I was able to put them on 143 grain and 165 grain bullets that were hardened and shrunk in this way. This will work if you know how to do it and your patient. That said this was just my experience yours may be better

  6. zero barrel leading 5 Star Review

    Posted by on Dec 5th 2016

    These gas checks are the perfect answer to lead bullets with plain bases. I press them on using a .431 die and they fit exactly the way I had hoped. Great product and I WILL be ordering more.

  7. Luv them boolits! 5 Star Review

    These plain base gas checks are the coolest things since metallic cartridge cases. Getting them on requires a bit of TLC since they are thin and the bullets weren't designed for them. But the results are amazing. No lead on the bore even when pushed hard. Velocity I never dreamed of AND good accuracy.
