    H4895!?

    Even more useful than bickering or calling BS on a niche use case for an alternative powder (H4895 reduced loads)... You could actually experiment yourself and provide some useful data to other shooters here at SH. I lead by example in the case of IMR 4895 and would be happy to share if others...

    H4895!?

    FWIW I am trialing some reduced loads with N-135 in 308 using the 125 SST. I will report back if there are any ignition issues in cold weather. I have used IMR 4895 for reduced 308 loads with identical results to H4895, again using the 125 SST. No ignition issues even with charges in the 60% of...

    308 win Winchester Brass

    Another thought if you want to continue to use some cases with looser primer pockets that aren't otherwise completely trashed - some primers fit tighter than others. For example Ginex LRM primers are VERY tight in new brass, and a touch larger in diameter than the standard primer brands (CCI...

    Why are basic bolt guns so hard to find?

    The market has spoken and hardly anyone is buying them... So why would someone manufacture them if the demand is so low? Either find a vintage BDL varmint, build one off a 700 action (a SPS Varmint would be a good action/barrel donor with a replacement wood stock), or get a Sako/Tikka. I...

    Converting a mid length 16" to rifle length 18"

    That is a problem with the barrel, not necessarily an intrinsic problem with the 18" rifle gas setup

    Fast burning, large grain powder like Trail Boss

    Great find, looks like a 5744 clone...

    Fast burning, large grain powder like Trail Boss

    Actually most of these suggestions are not very good. A powder like IMR 4227, AA 1680, etc is completely wrong for a low case fill application IE subsonic in 308 Win. AA5744 is pretty much unobtainable. There are several other threads about this, as well as data in "subsonic loads" sticky. A...

    Converting a mid length 16" to rifle length 18"

    Maybe, maybe not. Shoot it and see. Too many variables to assess. I have one large frame AR that ran like crap without being tamed with an AGB. Another one was a Criterion 16" rifle gas. That ran like a sewing machine right out of the box with no issues. Didn't even use a fancy heavy buffer.

    Converting a mid length 16" to rifle length 18"

    You don't necessarily need an adjustable gas block with a suppressor. A pleasant side effect of your switch to an 18" rifle gas is they tend to run smoother and be much less prone to overgassing than shorter barrels/gas systems. I shot out an 18" rifle gas barrel (over 9.5k rounds) with almost...

    AR10 6.5 Creedmoor problems.... Need Help Bad

    It may or may not be possible to salvage a functional rifle from your collection of parts, even if you try the gas block, buffer, etc tricks to try and get it to run. Sometimes there can be tolerance stacking (this means still in-spec!) and function issues even with high quality parts (JP...

    Night Vision Basic Thermal Clip ON Q's.

    The FOV and menu locations are different for every clipon. I have experience with the SNIPE-IR, Clip XELR, and PoT products. All would be "optimized" in terms of resolution, ideal base scope mag, and maximal minimum usable mag with different optics. The ideal optic for the vast majority of...

    308 DMR optics

    There are lots of good options that have been posted here. I have some decent optics including a Schmidt 3-20 and the XTR 3 in 3-18 is a pretty good optic for the $$$...

    PRI Mk 12 Mod 0 gen III: how gassy with a flow-through suppressor?

    An appropriately gassed 18" rifle gas barrel generally is about the LEAST gassy configuration for a suppressed AR. They tend to tolerate a suppression even without fancy tuning tricks. I shot out an 18" MK12 barrel with over 9k rounds and never had a single malfunction, with the majority being...

    22 Creedmoor and 60 grain VMax..

    I would consider H4350. The burn rate is close to ideal for this bullet weight. I have seen 3600 with 64 grain bullets with moderate loads and didn't see the need to push it further. If you throat is rough, and you have a fast twist barrel, you may very well have exploding bullet syndrome of...

    Lightest centerfire suppressor

    Griffin Sportsman UL HD is another option if you wanted to go all steel... But about 2.5 oz heavier than the ultralight Ti designs here

    Remington M700 6.5 Creedmore opinions.

    It may or may not shoot as you hope. Factory Remington barrels are a crap shoot in terms of quality. Just because an auction says a bright bore doesn't mean it isn't shot out. Also I am not sure what factory Rem 700 model came with a threaded 24" barrel and a laminate stock. It may be an...

    Looking for data 300grn 44 slow slow slow

    This is good advice. You want a fluffy, fast burning powder. The VV pistol powders that are extruded also work pretty well too. While not in 44 Mag, I have experimented with a variety of powders in this capacity including N340, Red Dot, Bullseye, etc and all have worked fine in 45 Colt and 300...

    What is a good receiver set to do an AR10 build with?

    Lots of great options... If you wanted to spend some scratch could always do a SR-25 lower/MWS upper. Despite being different brands they mate almost 100% and look factory. That being said I screwed together a Palmetto PA-10 and the receivers themselves were of perfectly adequate quality.

    22 creedmoor

    My understanding of N555 is that it is a similar but slightly slower burn rate to H4350, which should be perfect for lighter bullets. If it over-pressures before max with lighter bullets that would seem to indicate to me that it is not optimal for heavier bullets. N560 seemed absolutely...
