could you tell me the plus and or minus .
I was going to give them a try and my range is 600 yd max?
Thanks

Range Report Shooting 190 smk out of 308? good / Bad?

Re: Shooting 190 smk out of 308? good / Bad?
IMO, it is a great bullet, and one of the best options for the 308. I chambered my 308 barrel for the 190 SMK and the 208 A-max. R15 and now R17 would be the best powders for it. It has a little more drop, but less wind drift than the 155 or 175 grain bullets at longer range. But, for 600 yards max, the 155 will be your best bet. The 190+ weights look better at longer ranges, but not so good at closer ranges. We are not talking about a lot of difference, but every little bit helps.

Re: Shooting 190 smk out of 308? good / Bad?
190 grains is not an unreasonable weight for .308 Win. When you go to a heavier bullet in a medium/small sized case, all your doing is trading more drop for less wind drift as Chad stated above.
In my opinion it makes a lot of sense to use heavier bullets because if you have a laser rangefinder, there will be very little uncertainty in the drop of the bullet, so a flat trajectory is not terribly important. However, the wind is <span style="font-style: italic">always</span> uncertain to some degree. The heavy bullet is less affected by the wind, so the uncertainty in wind isn't as critical. In other words, if you have more uncertainty with the wind than with the range, you'll hit targets more easily at long range with heavy bullets.
In that weight class, the Berger 185 BT is a better choice than the 190 SMK. It's got a higher BC and is lighter so you can shoot it a little faster.
Good luck,

This is my exact thought process on deciding on which bullet(s) to use for a given caliber. I want less wind drift, because majority of the time I know how far the target is. The wind is what will get you! I will also look at the VLD's when the time comes.

I love 185 VLD's out of my .308. I liked 190's too, but I think the 185's did a little better in my rifle.
Now if I could just afford them.....

Bill...at 600 you may not see much benefit on calm days.....in windy conditions , the 190 is a bit more forgiving, but as stated above they do much better in the wind out long past 600.

well from what it looks like to me the 208gn Amax is doing good.Dust Remover has done a lot of testing and getting good results.4.75 at 700 yards is good in my book.but hey this is something I want to try when it gets a little warmer.

Re: Shooting 190 smk out of 308? good / Bad?
I read a paper by Litz where he was suggesting that bullets of upto 220gr are the 30 cal heavyweights and are therefore these bullets are the appropriate choice for people seeking best performance in the wind.
I am stating the obvious, but his point was that what we generally consider heavy in 30 cal actually performs akin to a medium weight bullet in other calibres.

You are going to need a 1/10 twist or faster. Just so you know guys have shot the 220's out to 2700+ yards with 308's.

There's been lots of good results out of barrels up to 1:12. Mines a 1:11 from Schneider and it shoots them lights out.
I use only the 190 in my 308 for all ranges. That way I only have to deal with one load. Plus, you get used to shooting it and knowing the conditions and how that one load works for you. I use it all the way from 10 yards to 1000.
I like to keep things simple.

We've shot the 208 A-max out of 1:12" twist with good results. You have to push them near max, though.

Re: Shooting 190 smk out of 308? good / Bad?
I run a 1:12 barrel and only drive the bullet to 2610fps @ 85 degrees and 1000asl. Never had one go sideways.
