Build Time

[Anschutz]

Quick update. Stock is in. Scope is in. My time here is winding down so hopefully by Christmas I'll have it put together. Really like how the stock looks.

I ran some numbers using the vortex ballistic app comparing a 260 shooting a berger hybrid 140g at 2700 fps and a 300 win mag shooting a SMK 190gr at 2940 fps.

At 1000 yards:
260: 30.7MOA drop. Velocity 1512FPS. Time of flight: 1.486seconds. Energy: 710 foot pounds

300 win mag: 27.71MOA drop. Velocity 1508FPS. Tim of Flight: 1.426seconds Energy: 959 foot pounds

So a 260 has ~10% more drop, ~74% of the energy at 1000 yards. The 260 will get the job done with less powder, less recoil, and better barrel life. A 243 shooting a 105g berger hybrid at 3000fps will drop even less than a 260 or 300 win mag, and has ~500 foot pounds of energy.

That is a mild 260 load.
I've smacked a few coyotes in the 1200 to 1500 range with hybrids out of my 260.
It solves their problems with authority!

That's some shooting right there. I'm going to try to find a load that will get me in the 3000fps range with the A-Max but I think at that range the bullet would pencil through with a 243... if I could see/hit it at 1500 yards.

Been putting together some final pieces. Now only powder to go and there are so many choices. I'd like to get something that will get me in the 2900-3k range with the A Max. I also would like to stock up as more than likely powder will likely be in short supply soon. I'm thinking 4895 is a safe bet but it'll be a little slow though I can use it in my 45 70. I'm thinking reloder 17 or 22, ramshot hunter or magnum, or h100v. There are many options out there and my reloading experience with the 243 is limited. Thanks

I don't know if I'm reading this right but you mentioned 4895 being "a little slow" but all the powders you listed are slower (burn rate) than that. Did you mean velocity slow?

I usually pick a powder that fills the case and gives decent velocity. Some instances I've found that faster powders that don't fill the case ended up being better (like H4831 in my 7-mag) but I always try high-density loads first.

Edit:

I wanted to add that IMR-4350 was awesome in my .243Win with 87gr V-max and 85gr Sierra. Can't remember the charge weight off the top of my head. I don't use those bullets any more.

Also it worked well with 70gr Nosler ballistic tips (which I bought 1000 of so that's my .243 coyote bullet for a long time).

I agree
4895 is way to fast of powder

H4350
H4831
7828ssc
roader17,19 and 22
Also look at 4451 and 4955 in the new enduron powders, those and the two Hodgdon powder are nice as a hotter load is less likely to bite you in summer heat and 243 can get a bit spooky

Are you using the 105gr Amax? if so, i would recommend waiting for the hornady ELD 6mm bullets to come out, and they are soon. If not, you will probably get better results with the 105gr hornady HPBT. I believe hornady is discontinuing the Amax due to the polymer tip not holding up due to heat at high speeds and long distances.

I use Reloader 23 and get great results with it out of my 1-8" twist 243 using the sierra 107 match kings and the hornady match bthp's. no matter my powder combo, i was unable to get satisfactory loads with the 105 amax.

Yes, I meant slow velocity wise. 4895 is to fast of a powder to push the bullets out quickly. It has produced good accuracy in Dad's Savage FTR though back when we were practicing together for that, I could shoot easy 3/4" groups at 200. My wind reading is pretty awful though so that's something I'd like to get better.

Steelhead, I'm thinking 4451 may be the ticket. It's pricey buy I'm also looking at doing a WSM barrel in the future and that will be usable there according to Hodgdon. Thanks

Bought some bullets and powder last night. I have 200 105gr AMAX on the way with some Ramshot Hunter. Base, rings, barrel nut wrench, and headspace gauge on the way too. Parts should be complete. Thank you all for your help with this build, even those who have disagreed or provided criticism. It should be about 13lbs all up. In the future I may have bottom metal and a Rifle Basix or similar trigger installed.

good luck with the amax. if you get a good load that works past 200 yards, please post. i have a box collecting dust i wouldn't mind to utilize.

edit: sorry, wrong link.

I will do that. I plan to get zeroed and then load test at 200

Rifle is built. I was only able to zero at 25 in the local indoor range but really like how it feels and looks.http://uploads.tapatalk-cdn.com/20161231/f20487500c4d045bbe932a6f92538355.jpghttp://uploads.tapatalk-cdn.com/20161231/cf0d9a6f92d7ac39728de3e2d76f123a.jpghttp://uploads.tapatalk-cdn.com/20161231/7329924060f953196079bb26fd54c76f.jpg

Did some load development yesterday. Had 6 of ten loads umder 1/2moa. And these were my best. I was shooting at 100 yards so I'll test at 200 and 300 next time out. 105 amax at 2.81coal and Ramshot hunter.https://uploads.tapatalk-cdn.com/20170122/4920ff0610c4b436ec61a4a7a7200cc4.jpghttps://uploads.tapatalk-cdn.com/20170122/495ed7066e739604b0a0291107b5ecdf.jpghttps://uploads.tapatalk-cdn.com/20170122/e01a7e37ee2fd8d03c5f2d1493cde753.jpg

Nice build, wish stock barrel was 1-8 twist.
