    I've heard that " cut down the recoil spring to increase the rate of fire" before. Complete crock. Softer springs will slow things down, shorter springs slow things down and they both allow the gun to beat itself to death. Stiffer or longer springs speed things up.... 60s are fun to shoot and...

    I think the best thing he gave us was term limits for the office of the president. Just need to get that worked out for congresscritter now. Frank

    Maggie’s Funny & awesome pics, vids and memes thread (work safe, no nudity)

    What makes you think that FDR thought an alliance with fellow socialists was a bad thing? His ideas and policies weren't so different than stalins. Maybe not so much murdering millions of jews and undesirables but more of the control and squeezing the people for power and money. He was just as...

    I'm pretty sure its not running JP8 filtered or otherwise. The Falcon nine is but the starship runs Methane chilled to liquid and liquid oxygen. There is a lot less soot that way and it is a fuel that can be sourced on mars. Frank

    The MP5 doesn't have as much poop to worry about so it isn't as destructive. Use your best judgement based on whether or not you can feel the bolt/carrier hitting the buffer and endcap. With the full power rifles you get damage to the buffer but also the rollers try to pop out when the carrier...

    Do you have the right locking piece in that HK? The cans tend to make them beat the crap out of themselves with the standard LP installed. We normally run a 35 or 40 deg LP to keep it smooth and soft. Its quieter too> Frank sorry no tittie pics or other stuff....

    Where’s the 12.7 Blackout?

    The feds spent a bunch of your tax money testing the raufoss bullets on pigs to insure it wouldn't go off on hitting bone. I'm guessing the API and APIT won't pop either. Frank

    Where’s the 12.7 Blackout?

    I hadn't thought about the Norma Mag but it might work fine. The taper should come out when you run it into the expander die for the neck. Any body taper should fireform. I guess the only question is the wall thickness of the cases. I don't know if they're any different than the 338 Lapua. If...

    Where’s the 12.7 Blackout?

    I've had API and APIT pop at 800 yds when fired subsonic to start with. The key is hitting a hard target. They won't pop when they hit the ground unless they hit a rock at those speeds.... Raufoss is a completely different animal. Never shot any of them as the live rounds were worth too much...

    8.6 Blackout accuracy and barrel twist

    Pushing something for profit makes a lot of illogical processes make more sense. Pushing the 3 in twist is one of these things. Nothing in reality shows the high twist rate to be effective for anything but exploding jacketed bullets or making barrels tougher to make. Its one thing to spin up a...

    Where’s the 12.7 Blackout?

    A few reasons for the cavity, first it moves the CG of the bullet forward which can help stability. It also can help the bullet expand into the rifling. I've heard some other reasons but many seem odd. My guess is you won't get any better engagement if you're loading for subsonics. Not enough...

    Where’s the 12.7 Blackout?

    Sorry Dogtown, I don't remember the company that made my trimmer. I got it from Sinclair and its gold anodized....I'll have a look tomorrow. I did make up a pilot for it so I can trim without resizing. It fits the case mouth after I run the expander into it. Works great with a battery powered...

    Where’s the 12.7 Blackout?

    30 lb of bullets ain't much for a 50. I've got a few cans of 500 API and they weigh about 50lb ea. I did try running some of the spotter tracer bullets but the barrel has to be throated for them to work safely. If you don't seat them out far enough they compress the powder way too much and...

    Where’s the 12.7 Blackout?

    Brass is a pain to make up for the 510 Whisper but once made it lasts a long long time. In fact, I've never worn out or cracked a case. I use a harbor freight micro chop saw to do a rough trim on length then run them through the expander die to remove the taper like Dogtown noted above. After...
