243 & 105gr A-max?

I have a 243 with a 1 in 10" twist and I want to shoot the 105gr A-max? Does anyone have any experience with this setup?

Thanks! [img]images/icons/smile.gif[/img]

Not sure, but a 1 in 10 may not be fast enough to stabilize the 105. I shoot a 6 Rem AI with a 1 in 8 for the 105 to 107s. You could try and see what happens though. I would recommend you begin with I-4350.

You need the 8" twist.

Re: 243 & 105gr A-max?

I have had A LOT of experience with this pill and caliber! Actually, just got back from the range shooting a bunch of them. The rifle (my wifes) is a Weatherby Vanguard .243 and it LOVES the 105's (NOT the 1:8 twists though). I set it on top of 36gr Varget, seat out .001 from the lands, and it will get MOA accuracy at 100yds all day long. Took me a while to get my seating depth just right since the Weatherby has so much freebore, but once I hit the "magic COAL", groups tightened right up and they have proved to be VERY reliable and consistent. What type of rifle are you using? Sometimes, the 1:8's will work for a particular rifle, but in mine, they don't shoot very well. All in all, it's a fine bullet and very easy to load with. I would recommend it highly to you if you want to gain more in terminal ballistics. Good luck.

I have a H&R Ultra Varmint that I will be using until I get a better long range setup. My intention is to target and varmint shoot out to about 600yds.

Re: 243 & 105gr A-max?

That's not too bad of a setup to start with. You may want to consider rechambering the bbl you have for a .243 AI chamber. I've done that with several of my .243's and had good luck every time. They have all been able to hold their own at 600yds without too much trouble. Another thought would be the 6/284. That would definitely get you out there. If you're shooting varmints, then, depending on your twist rate, you could probably find some good results in the smaller bullets as well. My first (and only) 6/284 was my doggin' rig for several seasons and it had a track record of 638 out of 804. Greater than 90% of these shots were over 250yds and many of them extended to as far as 700 or so yards. I think you could probably do a lot with what you have unless you really want to see what the 105 A-Max can really do to prairie dog! It's definitely a quick (if not sometimes messy!) kill, I do know that! Anyhow, that's a good bullet if you want to get out there. Do you know how many shots have been through the bbl? I have noticed that my .243's will eat bbl's alive if I shoot all my loads at or very near max.

I had a 9 twist 788 in 6mm that shot them well, but a 10 twist 788 in 243 shot consistant triangle three shot groups at 100 but they were about 1"--that told me the bullet liked the gun, but the gun didnt like the bullet so 1" was the best it could do because of stability issues.

a better option would be a berer 95gn VLD--similar BC to the 105 but light enough for a 10 twist.

also 80gn ballistic tips work well
