I have been reloading the hornady 139btsp in my dads browning safari 7mm rem mag for about the last dozen years with 70g of rl 22 in winchester nickel cases with cci large rifle primers at 3.224". I found that load in modern reloading as it was the only book I owned for a long time. My 60yr old dad can consistently put 3 shots inside an inch at 200 yards. Its the only load hes ever used for deer in that gun. I recently bought the hornady #9 reloading manual and that load according to them is over 3grains above max. I noticed they list it for ALL the 139g bullets they make. If you had a good load that you were using for a long time and then one day it is suddenly too much, would you change the load? I told my dad this and mentioned that if we worked up a different load, we could update to a bullet with a plastic tip. He said what he has been using as long as hes had that rifle is just fine.
