    Horizontal Stringing

    Re: Horizontal Stringing IME horizontal stringing is usually me goofing the shots. Either poor trigger control or position behind the rifle. Load up and re-test those particular groups to confirm.

    "Quieter" powder?

    Re: "Quieter" powder? Same bullet, same rifle, VihtN550 is louder/more over pressure from the brake Than Varget in all the load development I've done with it. (even at start loads, when the 550 is producing lower fps than Varget)

    Understanding case neck runout

    Re: Understanding case neck runout The confusion is the two different ways of reading it.. There is TIR (total indicated runout) And just 'Runout' (or actual runout) Imagine your case neck to be crooked by .003" So your needle reads +.003 on the high side, and then drops to -.003 on the...

    NEED HELP 308

    Re: NEED HELP 308 If your getting x10shot groups @.6 then I would leave the barrel alone lol! I havnt used the 155palma, but that measurement doesn't sound ridiculously long or anything to worry about, Is there any particular reason you wanted to load them out to the lands? If not, then...

    IMR 8208 XBR

    Re: IMR 8208 XBR Nope I havnt tried it in .308, I shoot heavy bullets with Varget or vihtn550 So Im happy with those loads I tried the xbr in the .223 because Varget was filling the case (lapua) and crunching ALOT without pressure signs so I switched to the faster xbr.. Worked for me! NOTE...

    IMR 8208 XBR

    Re: IMR 8208 XBR I started a load for Berger 70vld's in a factory Steyr aug, (20" 1/9 twist chrome lined) But couldn't get over 2700fps with Varget.. 8208 xbr is getting me 2830fps with no pressure @24.7grns Which is quite a bit over book max, seated to mag length 2.26"COAL I havnt fine...

    brass ?

    Re: brass ? Always back off your charge and work back up again if your changing one of your components, especially brass. Err on the side of caution! Depending on how hot your normal load is (with the regular Winchester brass you use) Back off 1 full grain. If your only shooting a mild...

    Looong solid bullet.. Opinions?

    Re: Looong solid bullet.. Opinions? Forgot to add.. They DO have some of their BC data on the JBM website.. Listed under 'Extreme Performance' The 175grn I am using is listed at .570 BC (G1) Which is pretty smokin' IF the data is accurate..

    Looong solid bullet.. Opinions?

    Re: Looong solid bullet.. Opinions? Well I finally got an email reply from the manufacturer with some load info.. He suggested Vihtn550 as that is what they use for their military stuff. I already have 1kg of n550 so I loaded up and tried a quick OCW last night, I am pleased to say they shot...

    Berger 6.5mm 140 gr Target Hybrids

    Re: Berger 6.5mm 140 gr Target Hybrids Ady, if your interested in the hybrids, both Reloading Solutions and Tim Hanham's have .30cal hybrids in stock, there's a good chance they have some 6.5's too.. I nearly bought some 185's and 200's to try, but £52+shipping is a hard pill To swallow...

    Looong solid bullet.. Opinions?

    Re: Looong solid bullet.. Opinions? You mean a crow sat on its nest won't stop a 208amax? Lol, and I SWEAR the speed camera incident wasn't me.. I was at home all night.. The other reason for mag length, is if they are seated any longer the case mouth is over the recessed part of the...

    Looong solid bullet.. Opinions?

    Re: Looong solid bullet.. Opinions? Yep I've got all the OAL data now (I have all the hornady kit, I just hadn't got that measured before I posted here ) I knew they were going to seat deep (for a 2.80" COAL) because the ogive is so much higher up on these things, so all that extra bullet...

    Looong solid bullet.. Opinions?

    Ok, Went to a shoot show yesterday, and bought some solid Bullets to try. The company making them is local to me, is relatively new, And has little info on the bullets at the moment.. According to the guy on the stand, they have been producing/selling .338 solids To the military for a while...

    Problem with RCBS ChargeMaster 1500

    Re: Problem with RCBS ChargeMaster 1500 Also check a kernel of powder hasn't dropped underneath the black weigh table thing, Happened to me once and readings were all over the place driving me nuts until I found it! Never had any trouble apart from that tho..

    Question on 208 Amax, RL17 - Updated 8/19/11

    Re: Question on 208 Amax, RL17, and compressed loads Hey chaps, I'm also half way thru varget development with the 208's.. I have started at AI mag length, and so far settled on 41.3 gr varget in Lap body sized brass.. No pressure signs, and right on 2400fps With 20 ES and 6 SD so far.. It...

    .223 POI change with bullet

    Re: .223 POI change with bullet What physics do you require explaining? Lower impacts?? Your using 2 different types of brass for starters, so internal volumes will be different, giving different pressures. So there's a strong possibility the two loads are going to behave differently...

    Ladder test interpretations please!

    Re: Ladder test interpretations please! Faster loads can (and very often do) strike lower on such tests, It all depends on at what point in the barrels 'whip' the bullet exits the muzzle.. The faster bullet can exit sooner as the barrel is flexing upwards, giving lower strikes on paper, also...

    Two ? about loading for a gas gun.

    Re: Two ? about loading for a gas gun. Anything that promotes reliable feeding/cycling. Better to FL size rather than NS, some people like to give them an extra thou on the headspace, and obviously make sure the bullets have clearance in the mags. Some like to crimp the bullets too, but some...
