hi everyone...

need help with a load...

http://www.cpcartridge.com/45-70marlin-B.htm

Conley Precision Cartridge says here that if you have a + 5.5 at 100 yards 200 yard zero in this load you can almost effectivly have a 300 yard deer gun if you dont mind compensating 22 inches at 300 yards...i have a stainless guide gun without ports, assuming i will lose about 120 fps from the 18 1/2 barrel, what powder and how much would i use to get similar results????

also how are you loading this bullet. thanks for all the input and help

be kind, this is my first post...

400 Gr. Barnes O (Flat Point)muzzle 1900 / 3206 100 yards +5.54 / 1668 / 2470 200 yards +0.00 / 1464 / 1902 300 yards -21.84 / 1287 / 1471

boom stick, welcome to the forum. Cant help you with your load, but if you want an "effective" deer rifle then get a 300 mag, 1.7" high at 100, spot on at 200, and 7.5" low at 300. 22"compensatoin at 300

With all due respect, if you need a 300 yard deer rifle you have picked the wrong gun. Remembering to compensate for a -21 inch drop at 300 may be easier than remembering to compensate for a +5 inch midrange trajectory at reasonable ranges. I usually zero at 100 yards as most of my shots are under 50 yards. A fella could zero at 150 and learn to make hits at 200 when needed, I suppose, but 300 is a serious far poke with any 45/70 load. FWIW factory 300s clock 1700 fps and 405s start at 1200 fps from my ported Guide Gun, surrendering only about 100 fps from published ballistics. Anyway, why don't you bring your levergun questions down to the lever action rifles forum and set a spell?

I don't agree with the 45-70 being a 300 yard rifle, but here is my load (which makes me happy out to about 200 yards )...

47 gr RL 7, CCI 250 primer, Speer 400gr or Remingtion 405 gr bullets, for 1850 fps from an 1895SS (22in barrel).

Use sound reloading practices and work up!

Cheers,
Canuck

this is my only rifle...

maybe some day i will have more...

my dream three rirle battery right now is my 45-70, 338-06, 416 rigby

what do you think???

boom stick - The previous posters are correct. While the 45-70 is a great deer round for close shots in the woods or heavy brush, something like a 300 Win Mag is ideal for those long shots. My personal favorite is the 270 Wby Mag (for long deer shots). If I were going to add two more rifles to your rack, I would have a scoped 300 Win Mag, and a
375 H&H Mag. with open sights. Buy the 375 H&H before you buy the Rigby. The Rigby is a great round, but the 375 is "enough gun" for everything, as one members signature states, something like "375 H&H - one rifle - one planet". Welcome to this forum.
Best, Starcharvski

At most its a 200 yard proposition. If you want to stretch a little more range out of the 45-70 then go to a 350 grain North Fork at 2100 fps.

Here's my 400 grain load:
Marlin 1895 45-70
405 grain Remington JSP seated to 2.55" and crimped with a Lee Factory Crimp Die
Winchester brass, 2.1" trim
CCI 200 primers
48 grains H322 START
55 grains H322 compressed MAXIMUM
MAXIMUM yields 1950 fps from a 22" barrel
Adapted from Hodgdon #27

thanks for the great input i am taking all your suggestions in consideration

This is a handloading question, so I will move it to the Reloading forum.

Yeah, I concur with everyone else-- it's not any more a 300 yard cartridge than a 1000 yard cartridge. Once you need a table to figure the drop, you're not talking about normal hunting any more. (Incidentally, with the 400 grain bullets it's effective out to 1200-1500 yards, per the military experiments in the late 1800's. But it's extraordinarily difficult to hit anything at those distances. Here's the link: http://www.researchpress.co.uk/targets/sandyhook.htm)

But it'll be fine out to 200 yards-- that's no problem at all. Use the lighter 300 or 350 gr. bullets, and load 'em up hot. Get a load you like, and practice stalking and/or calling. Close the gap.

My normal load, which I won't quote from memory, and I don't have my notes handy, gives 1800 fps with the 405 Rem bullet. If I expected to have to shoot farther than 100 yards, I'd drop down to a lighter bullet. Great gun; great cartridge. But not for 300 yards.

The 45/70 lever gun with a 400 is a 150 yard gun for me. Because of bullet drop and the difficulty of accuractely guessing distance in the field. If I want to shoot long range, I get somthing that shoots flatter.

while this is my data from a 450 marlin, the same answer applies.

Sight the rifle in 1.5 " high with your most accurate load. TEST it at 200. then learn it from 20 to 200...

he round is very effective to 150-200 yards, in the hands of a "onegun" man that has fully learned that rifle.

While it COULD hit a deer sized target at 300, i believe it would be EXACTLY that.. hit it SOMEWHERE... but, of course, I am not a long range hunter.

if you are planning long long shots, the hornady 300gr HP might be your bullet, as it opens rather easily, and should still expand at longer ranges...

Congratulations! You have a hunting man's packing rifle. You will be hunting, not just shooting.

Because it is such a fine packing rifle, it is a shame to lard it up with scope, like some beanfield special.

Bear in mind that 90%+ of all deer are harvested at less than 150yds. 1800fps muzzle velocity, 3" high @100yds gives you a 150yd zero.

A 400'ish grain bullet at 1800fps generates some noticeable recoil in the 7lb Guide Gun package. Probably should master shooting that first before you start trying to go faster.

dla...
on the guide gun i have a leupold 2.5x fixed scope with detachable rings backed up with xo sight system ghost ring with a ramp front that i am thinking of replacing with a tritium front (formerly ashley)

i agree with you about the hunting vs. sniping thing. no offense to others it is a philosophy thing...if the deer, elk or whatever does not have a chance, it is not a sport or hunting...that was a big influence in the choice of this gun. my original question is about "can" it be done and done ethicly for
a sporting long shot on a small deer ect.
