Home Forums Reloading Big Game Rifles 243 with 105 AMax

Not many people do with a B.C. of .207, when the A-Max has a B.C. of .500

How well would this 105 AMax do on Mountain Goat? My buddy drew one of the two tags in the Bitteroot Valley and will be taking my 243 out west for me on his retun from beautiful NJ. He has been scouting and thinks the shot will be over 300 yds. I think I just answered my question.

Let me know if he needs more. I've got at least 1box of 50 and no .243.

I think that my Stevens 200 has decided it likes 43 grains of ramshot hunter for about 2950 fps. Retumbo gets me more speed but doesn't group as tight.

Man, I will have to check out some Hunter and I still have a bit of Retumbo left for the 243 as well. Might have to pick up some 105's when I get home.

Finally got to the range and chronied some 105s w/H4831 SC, Hornady cases, CCI 200s and got a five shot average of 3123 fps with a flattend primers but no hard bolt lift or other signs on the cases. 22" barrel. Didn't shoot for accuracy as I had 2 emergency plumbing calls as soon as I set up on the bench and had to leave. Typical.

Man, that is SCREAMING! Wow.. I will have to put H4831 on the list of powders to try with the 105.

I just did the Hornady Ballistics Calculator and this little gun is a cannon, 1153 Ft. lbs at 500 yds is amazing. I was shocked at the speeds I got.

Anyone have experience with 105 AMaxs and whitetails??

Thinking this load of H4831 at 3123fps w/105s is a bit hot as even tho I had no issues with a sticky bolt, the primers are flat, and 2 out of ten cases had ejector marks, and the cases stretched .005 at the web. These loads are 123 fps faster than the new Hornady manual. Any thoughts, I have 6 weeks till take off to my buddie's cabin in Hamilton MT. so I have time to test.

I would really give Retumbo a try. Start around 46-47gr and run a mag primer. It kicked ass when I used that combo.

Local shop has some on the shelf. I'll give it a try, thanx.

i think you'll be pleased with what you see. It seems a little goofy, I know, but the results I saw weren't at all. Good speed (3030fps, 24" barrel), and nice consistency on the chrony. It was fun, no doubt.

I'll throw a few thru the chronie and see what the 22" will do this week.

41.5gr of IMR4350 shoots lights out in my rifle, and would be worth working up to.

Sunday morning humor thanks to shefire.

who pissed in your corn flakes this morning?

you dig up a 3 year old post, just to post this?

Slow day at church.... you that bored....and you were done choking your chicken and still had time on your hands...

and I STILL like 105 grain Speers.... and don't need a BC of .500 to take a damned blacktail at 200 yds or under...

GFY and have a good day doing so...

Sheesh...what a putz..

Must be a man crush thing

I have been shooting 105berger hybrids for over a year. Using 41 grains of h 4350. Chronos at 2950, and shoots extremely tight. A good 105 bullet would work fine on the goat hunt mentioned above. I've killed lots of critters from Deer to coyotes to antelope with mine.
