I started loading for a 243 I picked up in late summer, havent used it much but managed to produce some remarkable results in record time.
I ended up with a load as follows which produced as close to a single hole group as I am ever likely to see!
100gn Hornady Interlock SPBT
Went out yesterday and it a fit of desperation having seen nothing else to shoot, decided to perforate some cardboard.
no rangefinder but i am guessing it was around 120-130yds.
first two shots were bang on the bull and about 1/2" apart.
My problem is that I noticed some of the necks and case bodies following on from that had black soot on them. I only fired 8 or 9 rounds of this load before and dont recall any of these signs.
I know this indicates a low charge that has not sealed adequately and I know that I obviously need to up the charge.
My question is I am only 1.7 grains off the VV load limit and 3+ grains off the Hornady load limit, if it shoots like this and the only side effect is a bit of soot am I nuts to try and work up another load with more powder just to stop a little bit of soot?
