007hunter Posted October 31, 2005 Report Share Posted October 31, 2005 I was reading in this months Outdoor Life magazine and they had an article on Point Blank Zero. I found this very interesting. What the article said was that by sighting yur rifle in (they used the 30-30 as an example) about 4 inches high at 100 yards you would be able to hit the vitals of a deer out to I do beleive 300 yards or a 10 inch circle by just aiming for the boiler room. They also gave a list of different calibers and how many inches high it should be sighted in at to get the PBZ. By doing this they said it is eliminating having to try to guess what the range is and aiming accordingly, since most of us get buck fever and can't think straight. This was my understanding of the article So lets here what you think of this method....should be intersting. I can give more details of what the article in case someone wants to give it a try Quote Link to comment Share on other sites More sharing options...
Reloader Posted October 31, 2005 Report Share Posted October 31, 2005 Re: PBZ Read that article and several others on the same topic recently. Iprefer calling it Max Point-Blank Range since the zero is not at the further distance like the term PBZ seems to suggest. IMO, it is a great concept but I would recomend a smaller "pipe" than 10 inches...like between 6 and 8...and thus a slightly shorter PBZ than they recomend. Especialy for Eastern whitetails and other smaller varieties. Quote Link to comment Share on other sites More sharing options...
AJ Posted October 31, 2005 Report Share Posted October 31, 2005 Re: PBZ Welcome to the world of ballistics. The max PBR method does work. Assuming you will be holding center chest for long range shots and low chest for closer range stuff. I agree with James, I would not use 10" as a vital kill area. I prefer the bullet to rise no more than 2.5" from the aiming point. If I am hunting woods and a doe is standing there only offering me a neck shot at 100 yards, I don't want the bullet to hit 4" above aiming point. At that point, you have to think about holding low on close shots. Close range shots can be immediate. I want to react not have to think about where to hold. On long range shots, everything is more critical. Take the time, think the shot through, and execute. As long as you know your trajectory and the range, it is easy if you use the PBR method or just sighting in where ever. With my 308 Win I shoot it in 1.5" high at 100 yards. This allows me to hold on fur out to 300 yards. Using a chronograph and a rangefinder make shooting fairly simple. It still means a shooter has to shoot at different distances to verify their load is performing like the program says it will. Get a good ballistics program and you can learn a lot about what cartridges will really do. Quote Link to comment Share on other sites More sharing options...
007hunter Posted October 31, 2005 Author Report Share Posted October 31, 2005 Re: PBZ Correction, the 30-30 has a PBZ out to 260 yards. AJ, by sighting your .308 in at 1.5" high at 100 yards allows you to hold dead on at 300? So the bullet only drops 1.5"?? Or does the bullet drop more but is still a killing shot?

[/ QUOTE ] He said "hold on fur" This basicaly means that he may have to aim high but does not have to put the cross hair above the animals backline out to 300 yards. Once your aimpoint is above the animal it makes holdover much harder to calculate. Quote Link to comment Share on other sites More sharing options...

AJ Posted October 31, 2005 Report Share Posted October 31, 2005 Re: PBZ Yep, my load is slower than typical as the barrel is only 20". I am shooting a 150 gr SST 2650 fps. When zeroed 1.5" high at 100 yards it reaches its apex at 100 yards (+1.5") and is 1" high at 150 yards, dead on at 175, 1.2" low at 200, 3" low at 225, 5" low at 250, almost 8" low at 275, and is under 11" low at 300 yards. I can hold on its back and still take it out at 300 yards. Most people shoot over animals from 200 yards and out. Quote Link to comment Share on other sites More sharing options...
