[QUOTE="Darryl Cassel, post: 5783, member: 34"] Brent In defense of what I said in the beginning, I stand corrected with the Matchking of .4 for the BC. that I did post. After retracing my steps on this topic, I had looked at the Oehler program and had gone down to far and into the 264 bullets of the Speer 140 gr. and posted that BC by mistake. After the thread got a bit heated, I went back to the Oehler Program and the "Green" Sierra manual and found that the BC of the 257 120 Gr BTHP was actually a miserable .370 BC which I ran the numbers on. I never corrected my first post of the .4----My mistake there. I repeated several times for those responding to go to that book as I then had two sources that said the same thing (or close) about THAT bullet (Sierra 120gr HPBT) which someone had mentioned would work at 1000 yards. It is my experiance (and others) with the 120 gr Sierra HPBT that the bullet dies at extended ranges compaired to other lighter bullets. I have three 25 cals to back up those comments. The Hollow point is huge on that bullet and it does not float well at all. Probably the worst bullet in the Sierra line. I think it really went downhill after S1 posted that the 120 Gr would work at 1000 yards and "this" I did not agree with at all because of the two sources saying the bullet only had a BC of .370. It had a very low remaining Foot Pounds of energy left at that range of 1000 yards. I also posted for "Foot Pounds" FPs which I thought everyone would know that the two large letters FP meant Foot pounds. The small s got hit accidently. I am not perfect and type fast most of the time. I have posted the Sierra BC from "Holmes" who has backed up what I was saying from the start after I found those two sources. posted 05-20-2003 02:13 PM -------------------------------------------------------------------------------- As per the Sierra web site: .257 dia. 120 gr. HPBT .350 @ 2400 fps and "above" .357 between 2400 and 1600 fps .330 @ 1600 fps and below Now if someone wants to hunt with a bullet such as the 120 Sierra HPBT at 1000 yards, I would suggest he has a lot of scope clicks available to him or he keeps his shots fairly close. There are better bullets made for the 25 cal that will reach out much better but, the 120gr Sierra HPBT is not one of them. I think we all (or most) agree to that. The original poster (Big Sky) said his shots would probably be in the "600 Yd" range and possibly to 800 yards and I agreed to those ranges with the 25 but, certainly not with the 120 gr and not to 1000 yards. I know of those who have used the 25 on deer at "extended range" without real good "quick kill" results and they were using GOOD bullets. It would be fine at the ranges that Big Sky mentioned he wanted to hunt but, only with a better bullet then the 120 gr Sierra HPBT. My 25 cals work real well on woodchucks with 100 gr Ballistic tips at extended range. Later DC [img]images/icons/wink.gif[/img] [ 05-22-2003: Message edited by: Darryl Cassel ] [/QUOTE]
