Re: .308 Bullet Weight effects past 1,000 Yds

I wouldn't say that I am good enough to make consistent cold-bore hits at 1K+ with the 308 launching 225s or any other bullet, day after day, month after month.

Few people could back up that claim, regardless of their rifles chambering or load.

For conversation, here is a pic of a target I shot with 208s, at 2480 fps via RL15. Range was 1120 yards. I needed two shots to get on steel that day, as I recall. After that I put six consecutive hits with .722 moa precision. The steel target is 15" wide by 25" tall.







Point being, the 308 has the ballistics to get there with accuracy, especially with a bullet with a BC in the .6's.

Reading and adjusting for conditions is the art of LR, and the 308 makes it a challenge that I enjoy.

Nice shooting! And i like your rifle by the way. I think 1000 yd cold bore shots are plenty do-able but i think its much easier to do with a heavy bullet moving much faster than the 308 is capable of. The weather conditions affect the 308's bullet to much to be a great 1k gun. A 1mph error in wind or a slightly temp affected powder unaccounted for is enough to miss a 1moa target. Especially approaching 1500yds, which is what this thread was about before i inadvertently hi-jacked it. My apologies.

I'd never argue against added velocity making it easier to beat conditions.

I suppose it all depends on one's purpose. I'd never promote the 308 Win for 1000 yard hunting.

At the same time, I'm quite confident I could make life difficult for someone at 1500 yards with my 308 and handloads, if things should ever come to that.

I would agree with that. You obviously have much experience with the 308 and i respect that. I would be eager to hear about your experiments with the 215 berger hybrid. That bullet and Re 17 could be very useful to me. I look forward to a write up

Following Shane's lead I put together a 208 amax/R17 load for my 308 tikka that will put cold bore hits on steel out to 1k. I haven't shot it much past 1k, but based on how easy it is to get a 208 amax on steel at 1k, I'd be confident shooting at man-sized targets at 1500 wih handloads. Of course, the usual excuse applies- my ability to accurately read the atmospherics will be the variable, not the load.

I have a speedie tag for your back yard, Shane. If you have a couple man-sized targets you'd be willing to put out at 1500, I'd be happy to lob some 208's in their general direction...

Re: .308 Bullet Weight effects past 1,000 Yds

Bushman, all bullets are effected by the atmosphere they go through and the closer they are to the target, the more they are effected 'cause they're slowing down all the time they're in flight. The problem is knowing what the conditions are throughout the bullet's flight to the target. How do you know what the wind is for each foot above your line of sight to the target and each 50 yards of range to the target your bullet's gonna go through?

The closer the bullet is to the target, the more it drops per yard of range and the more it moves sideways for a given cross wind. If the bullet goes through wind for only the first 200 yards for an 800 yard target, it'll keep heading the direction it was headed at the end of that first 200 yards.

If you've got a good zero for your load at different range increments for different atmospheric conditions, pick the one that's closest to your shot at hand, make a few small sight adjustments if needed, cross your fingers then shoot.

All of which adds up to a very difficult task of estimating the sight settings for a distant target based on the conditions and expecting the bullet to strike within 1/2 MOA of the point of aim.

I most certainly agree to everything you stated Bart.
