    Is .750 behind the gas block thick enough for an spr?

    You are correct. Primarily stress in the barrel.

    .308 Win and Berger 185 Juggernaut Tactical question.

    While the Bergers may be overkill for your needs and not worth the extra expense shot-to-shot, they do have no problem jumping. Even the Federal Gold Medal load’s OAL is only 2.785-2.790”.

    Opinions on AR10 caliber

    260 would be an excellent choice. It would be mine under the same premise I went with 7-08: I can make it from 308 brass I have on hand.

    Opinions on AR10 caliber

    This is what everyone needs to remember when they say the 7-08 and 6.5’s are neck and neck. That argument applies mainly to the 162gr Amax/ELD. And you need all the length you can get to make the 162 get some worthwhile speed. Not a good choice for a gas gun. I say this is a 7-08 shooter...

    Accessories WTB - Geissele MK18 Rail

    Looking for a Geissele mk18 rail. To avoid any confusion, the mk18 rail is around 16” long and has the Arca rail built in to the bottom. Black or tan is fine, and don’t care about condition as long as it’s serviceable. Thanks!

    AMP

    Even prior to the AMP, I would graphite the necks before seating. While it certainly helped some with the AMP oxidization, basically I just redid load development once the AMP was included. I use it every time, and the new load developments really didn’t change a whole lot as far as the load...

    AMP

    This is it right here for me. I did the torch and drill socket for a while, then ponied up for the Giraud. Add another $150 in torch components trying to improve the flame and its consistency over large batches of annealing sessions. I dreaded the process and usually waited until I had a...

    What’s the weight difference between the two?

    Range Report 5.56mm AR, BC vs Speed in 16” barrel

    At this time, the biggest factor would be what powders do you have, or have access to? If you have powders for the heavier weights, keep your focus on that. My pick for your use would be the old standby 77 Sierra. If you already have ELd’s that’s one thing during these times, but I personally...

    Night Vision What ever happened to the PVS-21’s?

    Oh I definitely wouldn’t buy today. Just years ago I thought the 21-style/design was going to be the direction future goggles went. You had improved depth perception, see-through lenses for when the lights came on or utilizing your weapon sights, and of course - at the time - they were...

    Night Vision What ever happened to the PVS-21’s?

    Or at least their concept? Ten years ago, I was fascinated by the design and that’s what I wanted to save for for purchasing. Got to dabble with a set as some guys I was working with at a time had them in their kit. Ended up with anvis 9’s for my own personals, but the 21’s have resurfaced on...

    Range Report 7mm-08 vs 6.5 creed, which is better ballistics

    The 165gr tipped Game king. BC starts right at .6 and then drops to .510 under 2600fps - According to Sierra...which means, historically, the advertised BC is going to be a little higher than real life. Their TMK starts at the same .6. Amax still has the edge on them. ELDM is even a bit...

    Range Report 7mm-08 vs 6.5 creed, which is better ballistics

    Long time fan of the 7-08. I chose it over the 6.5’s because of the long-loaded 162 Amax at the time I was switching from 308 about ten years ago. Like Lowlight said above, I really wish more companies would put some time in the 160ish class of bullets. Particularly Berger. While I still...

    Another FGMM Clone thread. Accuracy Issues

    RL-15 is the powder in M118LR (Lake City) over the years. Not the Federal loadings. The Federal military load is Mk316. Maybe was originally 41.75 of 4064 like the commercial GMM 308 variant, but not in any of the lots I’ve seen over the years. The commercial 7.62 version [and military load]...
