with a remington .243 caliber which bullet is best the 80grain or 100 grain?

Answer 1

It really depends on your intent.

What are you shooting at?

If you are shooting at Praire Dogs, I'd opt for the 80 gr.

If you are shooting at Whitetail deer, I'd use the 100 gr.

If you are shooting at paper and are interested in accuracy, then you have to try both.

I have a Remington 700 FS, and my rifle likes 95 gr and 105 gr bullets. It only shot about 1MOA with 100 gr bullets and about 0.5 MOA with 95 gr and 105 gr.

I shot one whitetail with mine using a 105 gr Speer handload, and it dropped the deer right in its tracks. I dug the rifle out again for this weekend and am going to try 95 gr. ballistic tips on a deer.

Answer 2

I just looked in both the Speer and Hornady reloading manuals, both of whom list both 100 and 105 grain bullets. Difference in guns for the testing really makes a noticeable difference in the results! The strain was showing heavily, though, in both guns and bullet mffrs for going up that mere 5 grains in bullet weight. Clearly one has passed the point of diminishing returns on power after 105 grains in the 243, and a case can be made for that line being at 100 grains! I don't feel good about using the 95 grainers, although I have used them and frankly cannot tell the difference in field results on autopsy to determine bullet performance from the trusty 100's. But then I use only Nosler Partition bullets on big game, because they are so forgiving, having the broadest dynamic range of any bullet made.

Answer 3

The 100 grain is intended for deer, and will do nicely for the classic heart-lung shot, although performance may be compromised if it hits bone.
The 80 grain is meant for varmints and is thus more frangible. A varmint bullet will not penetrate deer hide, but will cause a nasty surface wound which will be fatal some hours after you've given up the chase.
On the other hand, the 100 grain may shoot right thru a smaller varmint and go on to hit some poor sod in the next field, so be careful in matching the bullet to the game.

Answer 4

It would depend upon the twist rate of the barrel. The faster the twist rate, the heavier the bullet that it shoots well. There is an equation called the Greenhill equation that you can use to calculate the aspect ratio of the bullet that works best in you barrel and from that what bullet weight is best suited for your rifle. You can probably find it by doing a search online. You can also go to your local library and look up a book entitled "Understanding Firearm Ballistics" by Robert A. Rinker. The Greenhill equation and a very good explanation are found on page 141 in Chapter 12. It takes longer to explain it than it does to make the calculation.

Answer 5

Remington 80

Answer 6

I have a Remington 700 ADL Youth chambered in .243 Winchester. What are you doing with the .243 bullet? Deer? Varmint? Which one groups better out of your rifle and has enough power for your intended target?

Answer 7

with a 243 the 100 grain bullet is exelent for deer the 80 grain bullet is faster and lighter and great for smaller game such as varmints but overall the 100 grain is excellent for both and it is a good allaround bullet with great knockdown and velocity

Answer 8

For farther distances use a lighter grain, it will not drop as much.... so the 80 gain will be better, for close hunting 200 meters and closer use the 100 grain. I would zero my scope at 200 meters with the 100 grain and you will be good.... if your going for far distances then zero your scope at 300 meters with the 80 grain.

Answer 9

What are you shooting? The 100 grain bullets are good for deer. The 80s are for varmint.

Best.

Answer 10

I use Winchester 95 Grain in my Remmington Model 7400 243 and it works great, it's very consistent and tight patterning.
