Hi All. I am a nearly 50 year old reloader hailing from Johannesburg South Africa. I cast, powder coat and reload for 12G (slugs, and buck), my 9mm pistols for sport shooting and as of last night have started working on three cast, powder coated and gas checked bullets for my 270 Win.
The 270 molds in question are Lyman's # 280473 - 124gr, Lee's C277-135gr-RF and RCBS' # 82017 270-150gr SP. So far I have cast, powder coated and gas checked the first two for which I have load data from the Lyman Cast Bullet Handbook for IMR 3031. Haven't been able to track down anything definitive for the RCBS bullet.
We have access to some US propellants in South Africa but supplies are not consistent and prices are high so I'll need to be fairly sure of the data before splurging on additional propellants.
I would welcome guidance from anyone with relevant experience that they are prepared to share.
