Having scope issues with 1895 45-70

[Will]

Had some problems sighting in today
Well today was my first day out with my new 1895 GBL. I scoped in with a 2-7 redfield revolution scope and used the DNZ one piece base and rings. The rifle shot great with my cast loads but I ran into one major problem. I ran out of adjustment on my scope and I am still about a foot low. I am having trouble understanding this and am not sure how to correct it.

Anyone else using the DNZ one piece base and rings? Any suggestions on what I should do to fix this problem ?

I had the same problem with my 1895. I decided that adding a shim under the rear of the mount wasn't what I wanted.
Look at Burris Signature rings with the plastic inserts. Get a set of offset inserts. These let you use the various inserts to "shim" the scope.

How much shim you ask? Simple ratio and proportion problem. The ratio retween the height needed vs distance to target is the same as the ratio between rings vs shim needed. I would expect around 15 thou.

Look at Burris Signature rings with the plastic inserts.

Couldn't agree more with Brad.

A great system to resolve that kind of problem.

That happens with all my 03's...I use a small piece of Linotype spacer material under the scope...its soft ,won't hurt anything and is of the right thickness and there is no additional cost...
come to think of it I did the same thing with my Remington 700...
The scopes on the 03's a regularly shimmed (Rear ring) in this manner to give an additional 20 MOA for long range shooting..

 

[Brad]

Shims are easily made. Pop cans are good for very thin shims. Thin sheets of brass are easily found at hardware stores. A pair of good shears will cut any size and shape required.

This is what I use in my 338 Lapua to reach out extra long range....

 

[Will]

Thanks for the help. I'll order a set.

I'm really excited to get the scope fixed. I was shooting some really good groups for the first time out with the rifle.

 

[Brad]

What kind of loads?
Mine shoots well with almost anything. I shoot a 460420 flat nose plain base over 24 gr of 2400 most of the time. Shoots great.

 

[waco]

I'm running a 405-460V From Accurate sized to .460 lubed with BAC over 42gr of 3031 and getting one hole groups @50yards.
This is through my 1895 Marlin.

Burris Posi-Line rings and offset inserts are practically a requirement for any Marlin rifle or carbine, if for no other reason than to correct for the barrels seeming to always be a long way off from straight with the receiver. I like to mechanically zero my scopes (count number of full turns in and out on both adjustments and return them to the center), then pull the lever and bolt out and bore-sight the rifle using only the offset inserts. I get it as close as I can and fine tune at the range with the scope adjustments.

50 yards is a good distance to zero when bore-sighting, but you can check it the way it is right now and get an idea of where the POI is vs. the crosshairs and view through the bore at a given range, which may help you determine how much high or low you need to pre-set the bore sighting picture for elevation when using the alignment rings.

 

[waco]

What loads are you shoot Will?

 

[Will]

I was just shooting up some old ammo I had loaded up with mihec 462 hammers. I think they were loaded with 3031. I was just trying to get my scope close to start checking loads.

 

[Pistolero]

If you have W748 in stock, I have had great results with 56 gr under a 405 gr RCBS GC design.

This is tested data from Brian Pearce and is at trapdoor pressures due to slow powder. Shoots about
1-2" at 100 from my Marlin, chronos at 1750 fps, excellent hunting load.

I have fired that load Bill, it was accurate in my rifle. I went far faster with that bullet too.
I use a 420 plain base at 1350-1400 for most of my shooting because it is less abusive to me.
Worst I ever did was the first lever action sillouhette match I ever shot. Between the 40 targets and 30 or so practice shots before the match I was beat. Only ammo I had was a 425 RD bullet over somewhere around 48 gr of 4895. I was beat after 70 or so rounds of 425s at 1700 or so.

 

[Pistolero]

Well, uh, YEAH.

Heck, 70 rounds of an ordinary .30-06 hunting load in a row would be
pretty punishing, too. Never said it was a plinking load.

As far as faster - I took that bullet and the 405 Jbullets from Rem and Speer up to about
2100..........and decided that the fun factor for even a 5 shot group was LONG gone,
and I wanted to keep my fillings in place, so dropped back to 1750. Which will kill
a zebra or blue wildebeest nicely with a single well placed shot. That Marlin will take
loads that I won't tolerate, no doubt about it. Even with a Kick-EEZ pad (sorbothane,
really helps).

Yes, for fun shooting and deer, there is not need for anything more than the 420 at
1350-1400.

[Brad]

I shot a few, like maybe 10 or so of the 405 Remington over 2000 fps. Not much fun. I did hang a full pop can of water in front of a steel plate at 100. Hit the can square and found numerous little bits of aluminum can. Quite impressive.

My two black bears were hit with the same 420 plain base but at 1650-1700 loaded over H322. It leaded a little after 20-25 shots but that wasn't gonna happen in the field.

I will say this, my Marlin 1895 is the most agreeable gun I own. It shoots damn near anything I feed it. M

 

[Pistolero]

"Not much fun" -- I'll nominate that for understatement of the thread.

Yes, nice rifle. My only slam is on that damned safety. I accidentally bumped it on, and after a 15 minute stalk on a
really nice impala, it went "CLICK", which the impala heard and bolted. REALLY irritating. I have an o-ring in the
groove on it now and it cannot come one accidentally. Half cock is fine with me. Mine is a SS Guide Gun, Leupold
1.5-5, fixed the trigger pull and it is really a good rifle. Nothing out there that I wouldn't be willing to take on with
it, given the correct ammo.

The PH in RSA was skeptical of the .45-70, which surprised me. Apparently some guys had shown up with 300 HP loads,
and they were NOT shooting whitetail deer. My 405s at 1750 smacked the wildebeest nicely, and the PH was convinced,
esp when he found the fully expanded bullet against the hide on the far side after punching both shoulders. He was happy for
me to use it on zebra after that. He bought all my extra .44 Mag Keith loads for his father after the hunt was over. He and his
boss were fans of my ammo. I made 140 TTSX ammo for the boss's 7x57 and he was tickled. Dropped a big kudu at 200 with
one shot while we were there.

As far as the original topic. I just put the Leupold on with std low rings and it was nearly zeroed, so no good
advice there.

[Brad]

Mine is a std 1895 rifle. I prefer the longer barrel.
I have a Leupold 1.75-6x on it. I like those scopes, have one on the 375 H&H and 300 BLK too.

The guys I dealt with in RSA all used a 270 or 06. I had taken both, left all the extra ammo there. I used a 130 TSX on everything, recovered just one. It looked exactly like the ones in the ads.

This is the only rifle I ever fought to get sighted in. I grew weary of messing with shims and after getting the Burris Signature rings with the inserts I was sold.

 

[Pistolero]

I think that the TSX is an impressive bullet, but I used 160 Nosler Partitions, each one which was recovered
was, like you said, just like the ads. The one 140 TSX that the safari place owner recovered from the kudu
was the absolute classic version, like you said. Today, I might use the 140 TSX or TTSX, now that I know how
good they are, but the 160 Nosler Partition did great, too. I loaded for a friend who went to the same place
for her Ruger 7x57. Gave her samples of 175 Hornady RN and 160 Nosler Partition, her gun liked the 175s better.
She killed 7 animals, all with one shot, only recovered 2 bullets. She reports that they called her "Sniper Granny"
at the dinner table, as the guys with .338 Mags told of chasing wounded animals for half a day.

Never heard of these Burris Signature rings with inserts, will keep it in mind if I run into problems.

I made my scope mount from a piece of blank Weaver rail extrusion from Brownells, and just screwed it on,
no sweat. Apparently I lucked out.

[Brad]

I think it may be a case of a barrel not in line with the top of the receiver. Doesn't need to be off by much to cause issues.
