I have a couple of Thompson Center Renegades. I also have a number of different Green Mountain Barrels that drop into the Renegade stock. One of the barrels is a Stainless Steel 1/28 twist 28" barrel.
I was told about a new sabot out there by Sabotloader. Some of us have seen them used in the 200 grain Shockwaves. They are a blue sabot made by MMP. So I purchased a couple bags of them through MMP and then ordered some 10mm or .40 caliber .400 diameter XTP's that weigh 200 grains. I was told that they shoot excellent out of fast twist barrels. Sabotloaderl said he had shot the XTP's with 110 grains of Triple Se7en 2f.
So today I took the rifle out and the new sabot/projectile combination. I loaded 100 grains of Triple Se7en 2f and from the 50 yard line off a single Caldwell shot bag bench rest took my first shot.
I was using CCI caps. Unfortunately these were not the magnum caps. I have a brother living in the big cities purchase CCI Magnum #11 caps for me and of course he got the wrong ones. So I have 1000 of the standard caps to shoot off. I actually got a slight hang fire with the first shot.
Without swabbing I loaded a second 100 grains charge and fired a second and third. Again, a slight hang fire could be detected. On the 4th shot, a definite hang fire occurred because I was about to bring the rifle off the bag to re-cap. (group #1)
I then swabbed the barrel clean and went into the house and got some RWS 1075 #11 caps. I upped the powder charge to 110 grains of Triple Se7en 2f and shot another three shot group. With the RWS caps there was no hang fire. (group #2)
While this might not be considered a "traditional" load, it sure would be a good hunting load. Very accurate, and with the powder charge and projectile combination it would be hard hitting. It should expand excellent, and I think if all things work good, I will give them a try this deer season for a day or two.
