Anyone using heavier grain bullets in their 308

[mjh30]

I was wondering if anyone was using heavier grain bullets in their 308, such as Sierra's 200 HPBT or 210 HPBT, Bergers 210 Match target VLD or Bergers 210 Target BT long range. I was wondering if anyone was using these, what success they had, especially atlonger range and any load data anyone would care to share.
Thanks marty

I'm loading 208gr A-max in .308. It has the best BC of any bullet in .30 caliber except for the 240gr SMK. RL 17 is the powder to use, got the idea from this thread:

208 AMAX with a pinch of RL15 produces 2650 fps. Stays supersonic out to well over 1300 yards.

Thanks guys,I had read into the 208amax, but since I have some 200 sierra and 210 BT bergers, I figured I would work with those first. Set aside some new Lapua and Win brass for this, rifle has 1/10 twist with 24 inch barrel to work with. Figured a heavier bullet with a good bc would cut the wind a little better, we will have to see.

Wondering how those 208gr Amax would work in a 1:12 barrel?

I've tried the 200SMK to 1000 yards but I was getting more vertical than I liked. So I stopped using them.

2650 with 208 A-Max, that's pretty fast.

208s work fine in my 1/12 Rem barrel.

Check out the link to the thread that Farlar posted. There is a lot of info there. You are on the right track.

How many grains of Re15 are you using to get 2650 out of a 208 A-max? Also, is the powder crunching when seating the bullet?

im gettimg compressed with 178 amax rl 15 lapua

i'll trade some 178 amax for 208 amax or for some sierra 175 hpbt....

I'm using 208 amax's in my 20" getting 2620 on my last outing but that was entirely too hot, had pressure signs, I think the new lot of powder was a bit hotter than the last.

I'm going to back off down to about 2500fps and i'll still get great results.

You are correct in your assumptions about cutting the wind better. I was out last week shooting 800yards in stupid wind conditions (meaning they weren't that predictable) and the other shooter was using 2-4moa of wind correction, I ended up only needing about 1-1.5moa correction, he was using 155 Scenars at 2850.

They carry a lot of energy to the target for a long ways.
