    75 amax, will they work seated deep?

    guys, my friend has asked me to work up a load for him to shoot in competition this year in his custom ar-15 (single shot.. UK laws..) hes given me a box of 75grn amax to try, but they are too long for the mag, when seated with .020" clearance for reliable feeding, the ogive is inside the...

    How critical are you.....

    Re: How critical are you..... A good accuracy node should be forgiving of .1grn under/over, If your load isn't, then trickle slower?

    Anyone measure run out with new Lapua brass?

    Re: Anyone measure run out with new Lapua brass? I've never checked them straight out the box, as I always size and fully prep them as per usual routine.. Worry about any run-out AFTER you have done your prep, fire-forming should even things out anyway. Get them loaded and go shoot

    Molycoated vs Non-molycoated

    Re: Molycoated vs Non-molycoated 77gr IS pushing it.. But my mate shoots them ok thru his 1/8 twist Ar-15 rig. I would try a lighter weight first until you get to grips with it.

    loads for 22-250 and such

    Re: loads for 22-250 and such I've used 37.2grn varget behind a 52 amax for long time now, Works like a ballistic tip on fox, But I've just worked up a new round, and so far it's shooting like a laser beam out to 300yrds.. And devastating (literally) on fox, 40.7 grn varget 40 grn nosler BT...

    Should I switch from 155gr scenars vs 178gr

    Re: Should I switch from 155gr scenars vs 178gr With varget, I'm running on a slower node, preserving brass life etc, but it's damn accurate for me, 42.4 grns, lap brass, cci2 primers. .010"jump That's giving me 2600 fps out of a 26" 1/10 twist. That's barely enough to keep it supersonic...

    +/- .1 or .2 Grains a big deal? Hornady LNL AP

    Re: +/- .1 or .2 Grains a big deal? Hornady LNL AP Can I expect sub MOA or even .5 MOA @100yds? That depends on Waaaay more than just your powder throw Choose your powder for performance, and then deal with weighing it out. It's no big deal to throw your charge short and trickle up if you...

    +/- .1 or .2 Grains a big deal? Hornady LNL AP

    Re: +/- .1 or .2 Grains a big deal? Hornady LNL AP If your load is in the middle of a 'node' then +/- .1 .2 should be acceptable for hunting yes. That's why we run an OCW test, to find loads that are a little forgiving +/- giving the same POI. It's relative to cartridge size of course..

    Lee Collet collapsing cases

    Re: Lee Collet collapsing cases Take your die apart and clean/check it. It sounds like the collet 'fingers' could be stuck upward and together in the 'closed' position, so when you raise the case into the die, the case mouth is jamming onto the closed fingers and scrunching up the case...

    Re: Looking for Advice on bullets and dies Your suppressor gives you an extra 100fps...? Your bullet has already left your barrel by the time it's going thru your suppressor.. You may have got a corrupt reading from the muzzle blast without it, then a different reading with it on, but it...

    Lee Collet dies and dead length bullet seating

    Re: Lee Collet dies and dead length bullet seating +1 for the collet die, coupled with a redding body die, you have a very low cost and versatile combination, that can produce very straight (concentric) ammo For the bullet Seater, I would always say the redding comp Seater is worth the...

    Too much neck tension

    Re: Too much neck tension i have read on here before, that actual neck tension caused by sizing, can never be more than .002-.003"... the reason was something along the lines of, due to the metal properties of the brass, its 'elasticity' can only provide .002-.003" of neck tension. If you...

    40grn Nos.Btips 22-250

    Re: 40grn Nos.Btips 22-250 Well it's true that barrel replacement is expensive here, But I find myself leaving it in the locker more and more, and using the 308 instead for everything. So I'm thinking 'what the hell..' I'm going to just play with the 250 a while.. Screw the erosion!!!! See...
