300 win mag in Browning rifle
Hello everybody. I'm new here, but hope someone is willing to help. Recently I bought a rifle scope combo that I'd like to use for long ranges. I do alot of shooting in the summer and don't take it lightly. I don't expect to have someone tell me a load and I can run out and start shooting game from a long ways off. Sorry for the rant, I can continue with my question now.
The rifle I got is a Browning BBR in 300 win mag. I'm kind of cursed, cuz I like the Browning rifles, including their short magazine. The short magazine isn't that big of a deal in my 25-06 BBR or my 7mm RM A-bolt, but the 300 is longer than either of those. I did grind the rivet off of the magazine, pull the spacer out in front and grind as much as I could off. I then contoured it back to a good shape to fit the magazine box well again, and reinstalled it in the mag box. I gained 1/8" or so in OAL. But, I still can't reach the lands with bullets such as an Accubond. I'm gonna try some Speer Mag tips and some Nosler protected point Partitions. But, I'd still like a bullet with a high BC. I was gonna try the higher BC bullets, but seated as long as I can go. I was gonna size my cases with the Lee Collet neck sizer, and use the Lee Factory crimp die.
The scope I have on top is a Leupold LPS 3.5-14x50 AO. It's a solid scope, and seems to track well. It's sitting in Leupold rings, with a one piece scope mount rail. Everything seems solid in the mounting of the scope.
I have a Leupold RXIII range finder. I don't really trust it that much as the last time I was trying to range things it wouldn't range anything, even a truck from greater than 200 yds. But, I'm also thinking the batteries are low on it. I'll try putting new batteries in it and seeing what happens.
I have a few trial shells loaded up with the Speer mag tips, RL 25, Winchester brass, and Fed. 215. I haven't had a chance to shoot the rifle yet, except for half a box of factory rounds I got with it when I bought it. I don't know what weights of powder I have loaded up right now, as I loaded them two months ago, and haven't been home since then due to work. I have it all written down at home, on the shells and in my book.
The rifle I have has had close to 200 rounds through it, and has lots of life left in it. I would like to use this rifle on elk out to 600 yds. I plan on shooting off of a short bipod, in the prone position. I haven't had the time to o it yet, but I'm gonna do a trigger job on it and drop the trigger down to 1.5-2 lbs. That's where I keep the triggers on my other rifles at as well, so I'm used to the light trigger pull.
I think I'm on the right track, but I don't know how to use what I have. I know I'll have to shoot to the actual range I plan on shooting so I can figure out what my actual MOA drops are. Is there a way to get close, to save shells while target shooting, to save ammo a bit? I'd make a range card and tape it to the side of my stock once I have the field recorded info.
Sorry to ramble on, and I hope I didn't sound arrogant. I don't wish to be that way, I was just trying to get all my info out there.
Does anybody use a setup like this? Are high BC bullets necessary for 600yds shots? I hope to get my groups down to 3/4", is this a tight enough group for the shots I mention? I understand that a bullet will do funny things once it's getting out there and speeds start dropping. Does anybody have a favorite load they shoot out of their Browning A-bolt or BBR?
Anyways, thanks in advance for any help. Eric
