Re: 243win/95 bergers drops

An "Ackley Improved" chamber. Holds about 10% more powder after it is formed than a regular cartridge.

My original barrel was the model 12 26" varmint barrel 1:9.25 and the 95gr bergers would not group with it.

Just looked and they have 2 different 95gr hunting bullets

95 gr Match Grade VLD Hunting G1:0.480 G7:0.246 length:1.150" Twist: 1:9″ berger #:24527
95 gr Match Grade Classic Hunter G1:0.427 G7:0.219 Length:1.070 Twist: 1:10″ berger #: 24570

What I can tell you is that the higher BC Match grade hunting shot no better than 2MOA from my Savage Barrel which was a 1:9.25 and now shoot 1/2 MOA in my 1:8 barrel. To get any real advantage from shooting VLD's one is typically going to shoot the heaviest one that one can from your barrel. Poor grouping is how you can quickly tell that they are not going to be working for you in a given barrel. I wanted to shoot the 105's and the data listed for them is

105 gr Match Grade VLD Hunting G1:0.532 G7:0.272 Length:1.235 Twist: 1:8″ Berger #: 24528

So I let the spec for the 105 dictate which barrel to buy.

Looking at the 115:
115 gr Match Grade VLD Hunting G1:0.545 G7:0.279 Length:1.365 Twist:1:7″ Berger #:24530

You will note that there is only the slightest BC advantage in going to the 115 and it requires its own special twist rate and look at the length of that thing ! Not easy to accommodate in the typical short action 243 rifle.

I was thinking I was around 3175 out of my other rifle. I will double check slope height.
