Hi there, novice re-loader from Scotland, where I principally hunt Roe Deer, I've been trying out loads for .243 Barnes TSX (85gr) & TTSX (80gr) using Lapua cases, for my Sako 75 (stainless, synthetic) 21.5" barrel. I've had a good search round different threads here and elsewhere. As with you lot propellant powders are a bit thin on the ground. I started off with Hodgdon H4350 using loads provided by Barnes and/or Hodgdon, but even at maximum (no pressure signs) results were modest and MV was slower than Hodgdon or Barnes predicted (less than 3000fps) and it was very dirty, producing significant change of POI as the barrel got dirtier! I managed to get some Vihtavuori N550 and using the Lapua/Vihtavuori recommended loads for the TSX (85gr) and a big jump to lands (0.086"), at less than maximum load and with no signs of pressure, I am getting 3300fps and less than 1.0" groups @ 100metres, with little change in POI from clean and cold. Much cleaner burning! I'm inclined to think the loads recommended by Barnes/Hodgdon and H4350 are a bit timid? Anyway, I'll stick with the N550 'cos it works for me. However, I have no Lapua/Vihtavuori N550 recommended loads for the TTSX (80gr), despite looking everywhere. Since in general terms it seems to be that the slightly lighter TTSX has recommended loads (whatever the powder used) slightly higher than the TSX: would I be right in thinking that I could safely use my N550 TSX load (41.4gr as it happens) as a safe starting point for loading the TTSX? My reasons for using the Barnes are two-fold: we are beginning to see some land-owners over here demanding lead-free, but also I am impressed that there is less meat damage/loss with the Barnes than my previous (Sako Gamehead) ammo, and less risk of that meat being lead contaminated. Great forum chaps, thanks! alasdair.
