Is sub MOA possible with Cast ?

[Shopdog]

You have to have a gun capable of it first. Then the person has to be capable of it. Then how much time and effort you want to put into it.

Not everyone can do this.

This.... it takes dogged attention to details that honestly,most just aren't willing to invest in. Just finding the time for practice is daunting enough and unless you are born with some kind of mistic powers,practice is still the only way to get to Carnegie Hall...... think,shooting everyday.

A three shot group will demonstrate if you have a poor load. It might indicate if you have a good load.

BTW, think about why all the MOA "guarantees" are based on three shot groups. It is easy to get a MOA 3 shot group if you shoot enough groups.

I only tested three rounds with that load with a 5 pound trigger and only tested three more with the 2 1/4 pound trigger. Five pound trigger shot MOA and then I adjusted the 2 1/4 trigger measured .256”. Guess I got lucky two times in a row? It’s not the gun that can’t shoot MOA in most cases...it’s the person behind it.

After reading this thread, it should be obvious to you that with a good cast bullet bench gun, well cast bullets, and a good rest, you should be able to easily achieve sub MOA accuracy, or you are doing something wrong. Note you need a bullet and gun proper for the job... just because a gun is accurate with jacketed bullets doesn't make it a good cast bullet gun. Time to read a bunch over on the ASSRA.com and CBA forums, and pay attention to what they discuss. Those guys can be very serious about the shooting you propose.

One shortcut to moa with cast is to get a .30 br. with a custom barrel, Jewel trigger, and a few Eagan molds. In CBA benchrest comp. this is the ticket.

I have a .30BR but shoot bullets out of an NEI 4 cavity mould. I've got a .280something at 100 yards and a .527 at 200 yards with 5 shot groups. Mine were shot in registered matches. The 200 yard group was the hard one to get. I have other small 100 yard groups.

I used to shoot military bolt action matches at the red castle gun club at Tulsa,OK. One of the shooters was shooting a Swedish rifle that the barrel had been set back to shoot varmit bullets. He was a retired Marine so he could shoot. The match called for ten shots on 4 targets, 2 targets for group size and two for score. The match director announced Hank had just shot a 1.3 inch target but I had inched him out with a 1.2 inch score. The rifle I was shooting was a 1903 A3 2 groove shooting a RCBS 180 gr. cast bullet over 16 gr. IMR 4759 with a dacron filler. The rifle was stock and I used Lyman Molly lube. I ran a patch down the barrel every five years or so.

Well i look at it this way i wont keep a rifle that wont shoot at least 1 moa not all are cast shooters though a few are .but my eyes are starting to go so maybe not for long. Its a lot of development and time

If you already cast then I would say it is just a little more development to dial in a cast bullet load. For my current cast bullet rifle it was actually less time and trouble than getting a good jacketed bullet load. The rifle is just a bit picky about jacketed bullets.

Cast bullets that I used came out excellent the first groups I fired in it. I wasn't sure about shooting cast so I bought some from Montana Bullet Works (they cast using the same molds you can buy). My very first shooting session had groups of 1.5MOA or less. Less than one box of bullets was needed to reach 1MOA regularly.

Even my cheap Lee bullet mold (309-180) produced 1.5MOA or less groups on a regular basis with my first loads. Once I became more careful when casting then 1MOA was more common.

The truth of this is evident in the amount of pushback received when someone posts about being meticulous in cast, handling and loading cast bullets as well as being meticulous in case prep, etc.
There are also the contentions that sub moa is so easy anyone can do it or since I can't shoot sub moa with regularity then anyone who says they can is dishonest.

This may or may not be germaine but I just recalled hearing said, "I rarely miss in the field, I just can't shoot good on paper targets."

Remember guys, this is the rifle the OP wants to shoot moa with cast in (he says 3 - 10 shot groups).

i know a guy who says and does just that, my brother. his left eye was blind since his birth. i don't know if that causes him not to shoot paper targets or what? but in the "field", he is devastating!!! he uses archery, muzzle-loading and rifles. he is like a terminator, expect when shooting paper targets. his accuracy measures in feet instead of inches. every year about the time deer season begins, he'll bring me the gun(s) and say "shoot them". so i do. the mossberg patriot synthetic in 270 with 130gr nosler bt and h4831sc will go 1/2 - 5/8" groups at 100 yards(5 shots/bench). then i gave it to friend to try and it was 3/4 - 1" at 100 yards(5 shots/bench). so i give it to my brother and with 100 cartridges and he hunts with that.

I had a 7X57 that just plain wouldn't shoot from the bench, but was a tack driver off hand.

This is actually a common problem with some rifles. I suspect the problem is some kind of interaction between a rest, the stock and the barrel.

A possible solution if shooting from a rest of any type, the hand grips the fore end and then the hand sits on the rest. 94 Win and some muzzle loaders need this kind of treatment. I have found my Garand is better that way too.
