I would hardly get any mushroomed bullets. Deer would go 100 yards or more sometimes with marginal blood trials. Of course at times I would get deer drops or massive blood trials but so far using the Barnes Spit fire EZ bullet, no only has my accuracy improved some but bullet performance has been OUTSTANDING!!! From 52 yards out to 211 yards on a 326lb mule deer, devasting results and near 100% weight retention! I really hope the Barnes bullets group well for me otherwise I plan on trying the Accubonds, sorrcios ect...
I tried the Scirroco bullet in 150g probably 12-13 years ago. I had been shooting RL 22 and loaded for that bullet in several different 7mm and experimented a .5 of grain at a time between 66 and 69 grains through 26" barrel and 24" barrels. At 67 grains, I was averaging 3100-3150 fps out of 26" barrel from three browning A bolts and almost 3000 in a Rem 700 24" barrel. One of the guns likes 68 grains (which is over the posted maximum) and shoots 3280, which is really fast and it's accurate for a factory gun, averaging 3/4 " groups.
I hope this gives you some knowledge on where to start at if you get the 7mm. It has proven to be an accurate and devastating combination on mule deer and elk out to 500. I haven't had an opportunity to shoot it further than that on any big game yet.
I have since picked up a .300wm in a stainless A Bolt 2 and have been hunting with it for the past few years.
