270 sendero it is a win m70 short action with a #4 28" lilja barrel with a pk brake and the full Kirby touch to it.The stock is a thumb hole laminate pillar bedded and that's about it other than it's a shooter just like all my APS rifles
I have a muz brake from Shawn Carlock and adjustably cheek piece. Still using the beaver tail stock with the aluminum bedding block What scope are you using??
Does Retumbo powder = a lot of recoil/muzzle blast?
Hi all, I've tried many combinations and am getting great results with 165gr but I also getting massive recoil and muzzle blast with 65gr of Retumbo in a 24" barrel 13.5lbs rifle.
I've tried a similar load (case full of Retumbo) in a 20" 243 Win driving a 105gr A-Max and the muzzle blast/recoil is impressive. A very similar load using H4831 showed minimal recoil (almost same muzzle velocity and powder charge).
My question is this:
Does Retumbo (or any slow burning powder) generate a lot of recoil and huge muzzle blast in 20"-24" barrels?
This reminds me of 357 Mag 125gr Win296 full load fire from a 4" barrel!
Yes, Retumbo will creare a lot of muzzle blast in any short barrel as it is a very slow burning powder. That is why it works so well in long barrels, i.e. more time to burn what's there. Recoil is more noticable as well. The old H-870 was great for this!......Rich
