    FYI I've pressure tested the "classic" Keith 45 AR load using a contender barrel and Oehler M43 PBL. I used a RCBS 45-255-KT cast of COWWs +2% tin (260 gr fully dressed) loaded over 6.5 gr Alliant Unique in Starline 455 Webley cases (same case...

    I really never found RBs that effective/accurate past 20 yards or so even with the best lad of 2.1 gr Bullseye. I too favor using my own cast TL314-90-SWCs TL'd in LLA, dried and then sized down to .311 loaded over 2.7 gr Bullseye in my 30-30s. ...

    Larry Gibson replied to a thread Lee Molds in Cast Boolits
    468 Of the numerous Lee 6 cavity moulds I use 4 of them are TLs and another 2 cavity is a TL also. While I do occasionally TL them in LLA (apply a thin coat as per Lee's instructions and let thoroughly dry) I most often "pressure" lube them in...

    Larry Gibson replied to a thread 308 boolit in Casting Equipment
    Over the years I have used all 4 of the bullets in numerous .308W and 30-06s with 10, 11, 12, 13 and 14" twist barrels. The 311466 has given the best and most consistent accuracy in all of them. So much so that I have sold the 311332 and the...

    Also consider there are muzzle brakes which generally just reduce recoil. There are also compensators which control muzzle climb during recoil. And there are the combination of the two; those that reduce recoil and control muzzle climb. Based on...

    A little better explanation or a picture of what you're talking about would be helpful. Non firearm related terminology is confusing to say the least. Just trying to help.

    Probably a better option is going to be a higher rear sight.

    I use a Lyman 358156 GC'd (160 gr) and seated/crimped to the bottom Crimp groove in Winchester 38 SPL cases, Winchester SP primers loaded over 13.5 gr Alliant 2400. Under 30,000 psi (measured in Contender barrel via Oehler m43 PBL) and gives 1200+...

    Years ago when I lived in NE Oregon I shot and tested a lot of lubed cast bullets at sub freezing temps down to -5 below zero. Most were in the 10 -12 to 40 degree range. I found with most all lubes it's the first shot or two, particularly from a...

    You're in business! With IMR4895 you will hit 100% load density before you reach max psi for your Marlin. Suggest you start at 50 gr and work up in 1 gr increments to 58 - 59 gr which is probable 100% load density with that bullet depending on...

    Also curious about what rifle? For cat's sneeze loads I'd look at the NOE 325-133-FN PB loaded over Bullseye (3 - 5 gr....loaded to 800 - 1050 fps). Or for a potential bit more the NOE 328-135-FN GC loaded over Unique up through 1800 fps.

    I use both IMR4895 and H4895 in 45-70 loads for 400 - 500 gr bullets both cast and jacketed. I use both to duplicate M1873 and M1882 (405 and 500 gr cast) rifle service loads. I also use a Dacron filler. I started using both powders years ago...

    I've chronographed several different lots of M855 out of several different 20" ARs and M16A2s with 7 and 9" twists. The M855 (US loaded with 62 gr SS109 type bullets) lot averages runs right around 2950 to 2980 fps. You'll lose probably 75 to 100...

    The form 1 (at least the form did when I filled it out years ago, don't know if the "blocks" are the same today?) establishes you as the builder of the suppressor/firearm when the form is approved and the tax stamp issued. Under the manufacturer...

    "Small base dies are only needed for the Browning BAR , REM 7400/7600, WIN 100/88 and Savage 99. And then only on a case by case basis." Bingo, give the man a cigar! I have sized thousands of LC cases (Match, M80 ball and M118SB) In...

    Ah, then you have far more favorable options, particularly with faster burning powders.

    Yes, I have rebuilt it (if you fill out one part of the form correctly rebuilding it yourself poses no problems) twice.

    If you are set on PCing and not using a GC then whether or not you can "get away with it" (assuming a reasonably accurate closer range load that functions your AR) is mostly going to be dependent on your AR. To function reliably the time/pressure...
