Stick with 243 handload for Speedgoats or try 7mm Mag?

Hey guys, I have found a very accurate handload for my 243. I am shooting a 100 gr Hornady BTSP pushed by 41 grs of IMR 4831. This is consistently giving my 3/4 inch to a little over an inch groups out of my Model 70 Featherweight. The 100 gr Rem Ultra Core Lokt is nearly identical with the same load.

I drew a buck antelope tag and the area I will be hunting is loaded with em. From all the yote hunting I do out there I know a few good areas to hit opening morning and as is standard with pronghorns the shots will prolly be in the 200 to 300 yard range.

I also have a 7mm Mag which is very accurate and I have reload dies for it as well. Would you stick with the 243 (I would really like to get my antelope with it) or in the event of a 350 plus shot on the buck of a lifetime (I know unlikely but always possible) would you feel better with 7 pushing a 150 gr bullet?

I took my first goat two years ago with a 30-06 150 gr. It went about 10 yards and kicked back over dead.

Last year I used 100gr sierra out of my .243. Shot one at 253 yards and it stood there for 20 seconds and then kicked over dead.

I am using my .243 again this year, but I am now shooting Nosler 95 gr.

Good to hear. I know the 243 is lethal I have taken one Mulie and two coyotes with mine so far, but shots were under a 100 yards on all. I feel completely confident in it's goat killing abilities out to 300 and just wonder sometimes if the 7mm Mag would be just that much more assurance in a long, long, shot scenario. But, then again I really love my 243 and want to get a lot of hunts under it's belt.

I reloaded the 95 gr CT's and didn't get quite as tight groups as I did with the ones mentioned above.

Part of the reason I've opted for the .243 is I have a Nikon BDC reticle scope so it makes shooting longer distances easier.

Of course, if my .270 win comes in before my hunt I will take it instead.

I love my .243 and have taken coyotes, whitetail and pronghorn with it. All one shot kills. But, if I get my new gun in I'll need to break that one in.

It would depend on how windy it was and how far I would be shooting.

Here are some groups from Sundays Shooting session. I have settled on the load outlined above. I have been averaging 1/2 inch to 1 inch at 100 yards consistently with it and I am currently sighted in at 2 inches high at 100. The first pic is at 100 yards and the second is at 250 yards. I shot one at 300 yard group I didn't get a pic of because it dropped about four inches and you couldn't see them well. It measured 3 inches. Due to the four inch drop I am going to adjust to 3 inches high at 100.

I am shooting a Winchester Model 70 Classic Featherweight and am pretty happy about the accuracy I've finally found coming from a light weight sporter with a thin barrel. I struggled to find accuracy at first and one of the biggest drawbacks was my set up. I purchased a Caldwell Rock Steady front rest and sandbags for the rear which improved my hold and accuracy immensely. The other was finally finding a good handload recipe. I shot a helluva lot of factory ammo and then since getting into reloading quite a few different handload recipes.

As the experienced guys already know a word of advice for beginner shooters. Make sure you have a good and solid rest from the bench or you will never know how accurate your rifle is.

And finally, I am ready for my Antelope hunt this year yeehaw! I saw a big buck off of my deck this morning as I was getting ready for work, a good omen?

And finally the rifle in question. I have a lot of confidence in this gun now that I've seen what it can do.

I would probably just stick with the 243. If you think you will have to take a longer shot go for the bullet that has the best B.C. in any manufacturer, it will stretch your reach a bit.

I think what Fuzzy was driving at is that the issue is not so much killing power (antelope are small and thin skinned), but wind drift, since it always seems to be blowing wherever antelope are....

Thanks Bitmasher and yeah that's what I was getting at with those groups. I'm happy with the accuracy I'm getting and decided to stick with the 243.
