I am still looking into the best combo for the 243AI as far as powder goes and some online articles suggest slower powders giving best velocity and life in the 243AI. I have a tin of 2217 (H1000) and have been fire forming with 47g 2217 under a 95g Targex. Anyone else got a load for either this or AR2226 (Retumbo) for the heavies from a 243. Plan to run two bullets. 95g Partition and 105 VLD.
James, I thought 2225 was the retumbo equivalent? How's she shooting so far? Any neck sizing issues?
Yeah, you're right 2225 is RetumboQuote:

I will show my missus the first three words from this quote James. I never hear those words in my house. It is also suppopsed to be the equivalent to RL-25. BB reckons RL 25 has temp issues and I have had some unexplained things happen with it as well. N560 might be worth a play?Quote:

Im useing n165 becsuase Iv got a heap of it, the 105 vlds are nudging 3100. anything in the 2213sc R119, R22 range will be worth a try.
I think I can get enough 2217 in. 47g in the standard 243 is about 90%.Quote:

Hows does it go.................if a man says something in the woods, and a woman is not there to hear him, is he still wrong?Quote:

RL15 works very well for me in the 7mm-08
I was thinking of trying RL17 in the 260AI.
I am no longer a speed demon when 1/2MOA is usually the difference.
RL-15 would be easier on the barrel I spose. I might scrounge some off you sometime James.
What load are you using in the 7mm/08 James?
I think 44.5g with a 140BT on top. I have a full tin if you want.
Cheers James. I would be better off with a sample in case It doesnt go that good in my rifle. Barrel wont be on till after I head back to Oz so I wont get much done till July. I would like it up and running before we head out with you and chase some Japs
Ill send you down a doggy bag
Ha Ha sounds great! Cheers

But with a 1:10 twist barrel so not the loads James will want, Sam (the claw) had load data with the 105 form firing and it was very accurate N165?Quote:
