I took my 300 win mag T/C Encore out tonight. I guess I don't know what I was expecting, but that sure was not it.
That is a scary round. I loaded up 168grn Barnes Triple Shocks with 71g of H4350. My chrony said the average was 3295fps (!!!) through a 26" barrel. SD was very tight... only 15fps from slow to fast. Yikes. Recoil from that light gun (no muzzle brake) was substantial, and I usually don't mind recoil. I shoot JC Garand matches with a 1903A3 and don't notice the recoil.
I sighted in 2.250" high at 100 yards, and shot a couple rounds at 200 to check the 200 zero. At 200 it was 3" high. I need to take a look at a ballistic calculator and see what is going on. The scope is not mounted that high.
I'd like to see/hear that sometime. :D
Okay...Looks to me as though it is currently set for about a 300yd zero. Playing with the ballistic calculator it looks as though 250 yds is the magic path... no more than about 2" deflection across that range.
I think that in order to do real load development though, I am going to need a lead sled.

Heck you can shoot it if you want. Let's find time for another range day.
Bring your hockey mask. Shooting off the bench, I dented my nose twice on the scope :)

That's why they invented ATV's ;D
Sounds like you had fun though.
Now if you want recoil, I built a single shot .308 on a skeletonized aluminum frame. The butt is 1/2" wide and it makes you want to cry when you fire it. Sure is easy to pack though. :o

From which end [scared]
A friend brought out a beautiful Browning 458 he had just bought to a range I was at----laid prone in the pea gravel and, I swear he slid backwards three inches when he lit that bad boy off. I never found out what kind of round/load he was firing-----he only fired one round and decided it was time to leave (He looked llke he was suffering a little buyer's remorse.)
I had a Winchester M70 express rifle in .458. Shot it a bit, never prone(!) and eventually decided that in the absence of a charging rhino, my .375 H&H would be all I'd likely ever need, and sold it. Those 500 grain factory loads pack a wallop at both ends!
Once read about a guy writing an article on an old british 8 bore black powder cartridge double bbl. dangerous game rifle (actually smoothbore until about the last 3 or 4 inches, then rifled). He was shooting it at a Southern Calif range, and a guy asked to try it. He agreed, the guy fired one shot prone and it broke his collarbone! This was a rifle that approached 20 lbs in weight.
:D My same friend used his 458 once more that I knew of----we were hunting caribou in Paxson, Alaska and he made a nice shot from about 200 yards-----the 458 entered dead on a forequarter and exited the opposite forequarter---when we got up to the very dead caribou we found that entire forequarter lying several feet beyond the caribou----he decided he had a little excess for anything less than a charging grizzly or polar bear here in Alaska. I don't think he ever used it again but it was a beautiful rifle!
