Re: Heavy Bullets!

LTLR one more question. What were the BC's you came up with for the 7mm 168 Lrx and the 338 265 Lrx?

Jeff how did you test the expansion? Could you post some pics?

Re: Heavy Bullets!

Thanks, i am thinking about building a wood box just the right size for newspapers to fit in snug and putting a piece of wood probably 1/2" thick infront held on by one screw on the top center so i can just swing it up and check out the damage. I am going to try some trail boss in the Lapua and see if i can get a velocity that will get me an impact velocity of 1600 fps at 100 yards.

Plus are you sure the bullet you are refering to will expand at all let alone at 1200? Might want to take that into consideration. I know I started my expansion testing of the bullet I hunt with at 1200 before I took them to any game. Where are the expansion test results of the CuttingEdge bullets? So far these pics are all I have seen.



I can't believe you said that.

Are we sure those are the CE hunting bullets and not the solids. I saw this pic on another thread and seem to remember there being some questions as to which bullet it was. These sure don't look like the bullets on their site. They are nicely mushroomed with some of the petals dis attached.

Can't say for sure which they are Scott. That pic was posted on this forum as results from an expansion test of Cutting Edge bullets. I did not do the test and so I can not say which version they are. But this is the only results I have seen done with any CE's. I would like to see more and may do some myself just to see first hand. I would think most responsible hunters would test for expanion before you hunt with them? Especially a non lead solid? Unless you are in the club like me that would shoot past 1200 yards and have no morrals and am not worthy..

Re: Heavy Bullets!

Initial drop tests with the 168 LRX to 1000 yards showed a .62-.64 BC out of my 7mm STW. I was easily getting BC's into the high .6's and Kirby into the .7's with the 265 LRX when it first came out. I do not have my data with me and going by memory. At one range session I remember Kirby saying it was grouping right with the 300 SMK to about 1200 yards. The BC can vary with each rifle and is not completely reliable doing preliminary drop tests but will put you in the ball park. When you decide on a bullet test it at various ranges to at least 1500 yards with excellent notes and checking it against your kestrel or ballistics calculator with every shot. With BC adjustments after each shot in the end you will have the exact BC according to your equipment that matches your data.

Just like shooting anything for accuracy. Repeatability is the only thing that matters. As long as your equipment gives you the correct data everytime for consistent hits it doesn't matter if it says .65 BC with your rig and the next guys equipment says it is .7. A hit is a hit and as long as your equipment matches what you are doing you are going to hit.

Thanks for the link to the bullet catcher. I am going to construct one out of OSB with a lot more dirt so I don't get shoot throughs. My 1000 yard target is supported by two short telephone pole sections. The 225 CE bullet hit one and blew half the back side out through a good size pole. Still have not recovered one. But with enough dirt I will.

EDITED BY LEN


Most all my hunting is inside 1000 yards and I shoot bullets that are ballistically superior to that distance at the range I most encounter game and give me the best chance for a succesful hunt.

You are worthy, and much respected. I look forward to your information. I personally will hunt all ranges out to about 1000. That is where I am comfortable. I want a bullet that will perform at everything in between. I have found that in the GS Custom Bullets. The 177g 30 cal will out run almost everything to about 2000 yrds at the speeds that I can launch them. The speed to bc ratio of this bullet makes it very hard to beat. It is also a true hunting bullet that holds together and deforms properly down to 1500 fps. It creates a square frontal area on impact that does more permanent damage than a rounded mushroom and insures deep penetration at any distance. No blowup or pencil.

If we are only allowed to compare bullets of the same manufacture and model then the heavier one will win every time. I am not limiting my comments on bc and weight to one bullet model. I am comparing long range hunting bullets of all makes.

Also the bc for any given bullet will change depending on the speed at which it is flying. And it will change on a curve through out its flight. Some bullets degrade bc faster than others as they slow down. Some get better as they slow down depending on the muzzle velocity. Tangent vs secant ogive. I will stand by my statement that it is possible to have a lighter vld type hunting bullet that has a better bc than a heavier vld type hunting bullet. This stuff gets quite complicated. We should not simplify it to say that heavier is always better. A 240g bullet is not always better than a 180g bullet. Unless the bc listed for a bullet is dreadfully wrong the bc is the flight characteristic that you will get. Very close depending on starting velocity anyway. I feel like I am starting to ramble. So I will stop.

Steve
