Re: Advice on Bullet Weight for New Build
The driver is always going to be more important than the bullet, and nothing but practice is going to make you a better driver. Guys shooting 155s have beaten guys shooting heavies in pretty much all wind conditions.
That said, windage is where most of your points are going to be lost, 155s pushed really hard still give up more than 185s, and 185s give up more than 200s, but there is a cost. Pushing anything hard is going to kill your brass. You can get loose primers in a hurry if you get the pressures up there.
Heavies have more recoil, more fatigue at the end of a match, getting pushed out of position more each shot.
I personally haven't run the 200s (yet) but what I read online from very good shooters who have is that they are more sensitive to technique, which makes sense, more recoil means the recoil cycle of the rifle will be effected more by variations in your position and will effect the poi.
Another consideration for me at least is that Bergers cost about 20¢ more per bullet than some of the other options. In my case I shot over 1500 rounds this yr in competition and practice. I have identical loads with the Hornady 178 and the 185LRBT. The difference is about 1MOA of vertical and the 178s give up about an inch per full value MPH, not something that I can hold, but something that will cost you a point here and there, but having a load with the 178s saves a few hundred a yr because I shoot them in club matches and most of my practice.
What kind of wind do you usually see at your range? Here in Oak Ridge - well, we have winds that you can't see
- but typically I never dial more than a couple of MOA so the advantage of the 200s is less, but at places like Raton and Camp Perry you can be dialing on 7MOA or more, and might get a minute or more less windage when its blowing. I got a little side by side practice at Raton with a friend shooting 200s, I was shooting 185s; in the wind during the Friday practices it looked like he was seeing about 1.5MOA less adjustment, or at least about a minute and a half less on the letoffs, but my 185s did win one match in the wind, and I believe Darrell said that there were matches won with 155s too.
Personally I would not set up to shoot 155s, but neither the 185s or the 200s would be a wrong answer.
