Kimber Montana 280AI... 140TTSX? - 01/27/15
I've been running a Kimber Montana 280AI with Z6 2-12BT, using Nosler Brass, 62g of R22, Fed215, OAL 3.325 for 3190fps... shoots great, but getting stuck cases, shaving the back of the cases and flattening primers on a semi regular basis in the field, but almost never at the range? I'm thinking I must be right on the edge of be too hot in the right/wrong weather/atmospheric conditions? Dropping back even half a grain blows groups right out to not good enough...
Looking at trying different powders after reading (and seeing my changing results) from the temp issues etc with R22...
Not wanting to change projectile as I use this rifle from Fallow to Sambar in Australia, plus Chamios and Tahr in NewZealand at ranges of 10m to 600m and like the way the pills preforms...
I have tried ADI AR2209 and R19... both grouped poorly and way down on velocities for my likings. Just picked up a few tins of ADI AR2213sc to try?
Anyone using the same-ish set up? Load data for a starting point? Ideas even?
Thanks in advance
