Here in the UK, there have been some Match Rifle comps at Bisley with F & FTR classes included, so I've shot my F/TR rifle 1100 and 1200yds with good results, but usually we're on a standard NRA(UK) long range target with a 24"Bull and 12.4" V Bull, so in good conditions it's not really such a...

Re: 200 berger hybrid for F-TR I've been trying the 215 and 230 Bergers for F-TR but so far haven't found a load that works well enough to switch from the 185 Juggernauts. Have you guys gone to the 200 because it's not as much of a leap into the dark as the 215/230 or have you already...

Re: Quickload & OBT prediction with 230gn .30 bullets Ah, hold on. I've just spotted that the X-axis on my graph isn't linear, so that would account for the ramp-up. I'll change it and re-post. Changed the graph and text in the above post. All seems as it should be now!

Re: Quickload & OBT prediction with 230gn .30 bullets My faith in Quickload has been restored! Did a lot more range testing today across a wider load/velocity spread and carried out group testing while chrono'ing every round. The results are summarised in this graph: The yellow line...

Re: Quickload & OBT prediction with 230gn .30 bullets No problem. Here is my starting load, before tweaking the burn rate. Actual MV was 2257. Quite a bit away from QL's 2374 fps.

I've had some very good results using Quickload to work out optimal loads for my .308 rifles with 155, 175 and 185 bullets. I'm now trying to get 230s working in my 32" 10-twist barrel but things aren't going to plan... I'm using Berger 230 Hybrids in Lapua brass with Reloder 17. The OAL is...
