I can't seem to make the time to get to a proper range that's longer than 100 yards so I improvised. Using my rangefinder I was able to indentify a recognizable object 300 yards away then take a rugged hike out there to set up a makeshift target. I dispensed with my usual 6 and 8 inch paper plates, going all in with a full size paper plate, which is 11 inches across. I stapled it to the stump of a fallen tree about two feet off the ground. I had to shoot slightly downhill.
I chose Norma match grade ammo. 220 gr. Mainly because I had an open box in my ammo pantry.
First I shot the older gun that has the long bull barrel. I had previously mounted and zeroed the Vortex scope at 100 yards. Five shots, 3 inch group. Not great, but not bad.
Next the new gun with the Sig BDX scope. I used the Kilo rangefinder and it's built in ballistic calculator. I have a Kestrel that can talk to the Kilo but it wasn't very windy or humid so I didn't bother to use it. Five shots, 2.25 inch group. That's not bad at all. Especially since the gun is brand new, not broken in.
A one inch group with 300 BLK at that distance is exceptional. 1.5 inches is very good. Either is cum laude territory. I think with a better trigger the new gun could do better. Likewise, if the older gun had the benefit of the fancier optics, it might exceed the performance of the newer rifle. It already has an upgrade trigger that breaks around 2 lbs.
Ceterus paribus, that extra ten inches of barrel should matter. Here's previously posted pic of the guns:
My aim here was to spend some more time with these two rifles and get them dialed in. Neither of them have had many rounds thru them. This is going to be my winter challenge to myself. Getting these guns as close to 1-1.5 inch groups as my ability will allow. My final act in that journey will be get the new gun to run reliably with a can. That was the whole purpose of getting it.
I have to be careful shooting on my own property because anything beyond 200 yards out is public land. There's nobody out there for miles and I have a clear line of sight but I don't want to shoot any deer hunters that may wander into the area. The 300 BLK is lethal beyond 300 yards. However, the drop is about 40 inches at that distance, so it's going to be in the dirt not much further out unless I aim excessively high. Distance-wise the max sweet spot for 300 BLK is around 200 yards. Beyond that you should be shooting something else. I figure if I can reliably hit a 11 inch paper plate at 300 yds, these 300 BLK guns are performing as well as can be expected for that caliber. Anything closer is gravy.
BTW: The blue gun was an 80% lower I milled myself. I bought the finished lower for new gun. It definitely needs a better trigger than the mil spec it came with. I have the upgrade trigger just haven't installed it.
