Hi guys and gals! i am pretty new to this whole long range shooting thing. I have been doing quite nicely with a 243 out to 600yds but had a question. currently i am using 87gr HPBT hornady with 39.8g of h4350 i get around 2900fps with this load. it shoots pretty consistently under moa. but then i loaded up some "hotter" rounds at 42.5g of h4350 and that gives me about 3000fps it also seems to group a little better but not a huge difference. now my question is should i keep shooting my original load or should i switch to the hotter one the reason i ask is it really a worth the extra powder and shorter shell life for the 100fps gained? thanks!
