<1moa 270wsm?

My understanding of "floated" is not touching the stock in front of the action, and not bedded in front of the action. The barrel fits the stock well, but as I mentioned previously, there is 1" of compound under the barrel which I will remove and see how it works.

Is this what you mean by floated?

I'm going to relieve the recoil lug as well, because I'm pretty sure the bottom is touching.
 
If the bore is that rough, consider hand polishing with some JB borebrite (red colour). It will knock the rough edges off the lands. Repeat as needed till you get some semblance of smoothness.

I think your pipe is pooched.

Maybe I should just patch thru some emery cloth..........

:)

I just missed a nice sized coyote at 320yds from prone, bipod. I ranged after the shot, but guessed 300, so I was close. I tried to hold about +10" but estimated it only, and didn't dial it on the scope (+3.25MOA ~) I found the impact later, so no hit, no blood. Arrgh. I gotta learn....it's too hard to GUESS hold over at distance because it's so dependant on target reference size.

SIGH. I'm learning.

Tomorrow is range day. I'll experiment with some loads, and try digging out the recoil lug.

Floated means free of contact. It does not usually matter if the first couple of inches in front of the action is not floated, but the rest should be. It is a simple matter to achieve this. I use a cigarette paper to guage whether the barrel is free of contact, it only has to be a whisker. When floated the rifle will sound quite different. It is not necessary to relieve the base of the recoil lug if the action is bedded properly. I think the reason relieving it was mentioned is that the action can not rock on it, but if it is bedded properly this will not be an issue, and the fact that it is not relieved can only serve to give the bedding strength.
 
Thanks Spencer. My barrel is definitely floated then. The action is really nice and snug in the stock.

As to the recoil lug, the excess squished out, so the action "should" be bedded OK. The fact that accuracy didn't change after bedding means at least I didn't make it worse.

My quest, if I choose to accept (I do!) is to make this sucker shoot 1MOA.

I'm gonna chrony and test the 73 and 74 gr H100O Wednesday, just to check that accuracy issue, then...I need to work up some other recipes.
 
Well that's one thing you don't have to worry about then.

My advise to you would be not to bother with the chrony, just develop a load that the rifle likes, the actual speed the bullet is traveling at is neither here nor there, you ain't going to notice the difference in any case. Try several loads all lower than what you have been shooting so far, so that you will have been from one extreem to the other, then you will for sure know what works best.

It's wednesday tomorrow, I will be looking forward to a range report. : )
 
I need the chrony data to build data tables for hunting and shooting unknown distances, and learning ballistics and environmental stuff. It's helpful for that.

If I develope a max load or max speed (which is around 3400 to 3500fps for the 110Vmax) then in the summer it will be out of spec. I need this info.

I'm not going by SD etc, to develope "the best" load though.

I have to go and "re-shoot" that coyote, so I'll be busy tomorrow!! er Wednesday.

You only need to build data tables when you have it shooting right. All you are doing at present is complicating things.

Why are you interested in "max loads" and "max speeds" ?
 
I'm interested because I'm 6 months new to reloading and while I'm doing fine, I don't want to stray into unknown territory. The 110's aren't supposed to be pushed past the 34 to 3500 or they'll start to come apart (supposedly). At present I'm at around 3200. In the summer, using the same loads I'd be hitting the redline.

You're right about getting it shooting first, but I am also enjoying the learning aspect while I keep tabs on the data.

Most of my loads right now...for instance for the .223 Tikka...are near minimum. It shoots so well I haven't strayed too far. My 75gr Hornady's come out of there at 2550 with 23.0 gr of Varget, @40F.

The 270 is the subject of conflicting load data from various sources, plus my gun is darn inaccurate, so far. Due to the pressures of the WSM, I thought it wise to track my progress with the chrony AND my group sizes.

Today I did get to the range for a rushed session to test 10 of the 73gr H1000. Group size did not appear to change although it printed ~2MOA higher than the 71grainers I used to do my fouling shots. I didn't have enough time to do a whole run up, or use the chrony. I just wanted to check something from a previous test session, as I stated in another post.

Now, I will put together a whole test regimen, and I will go slower than I'm at now to check them through the whole spectrum.

Thanks for being patient with my newby-ness.

At least I can shoot the 270 now without recoil problems. I figure that's something positive. I had to cure a flinch due to scope issues.
 
I have a Brownning stainless stalker in 270wsm and yes it gets groups under 1 inch all day long if I do my part, and it's 100% stock out of the box. I do have a Leo 4 X 14.5 Varix III on it though.
 
Well, I just dug up some targets that I kept from when I bought the 270. There were three three-shot groups on it from 100 yds at .680, .945, 1.50 for an avg. of ~1.0MOA

The cartridges were factory Federal Power Shok 130gr Soft Point deer rounds. I still have 10 from that box...guess you know what I'll be doing! What a perfect double check.

I did those groups right after I got the rifle, and the trigger stunk, and I wasn't used to the recoil, so my guess is, if the rifle hasn't changed, I'll shoot sub MOA with it. Which points to the 1-10 twist, and my underdeveloped 110Vmaxs as the culprit.

If I don't....I need a new barrel.

Does that sound right?
 
YUP!!!

Varmint weight bullets in hunting cartridges tend not to do well because they are so short. Most chambers have a throat set up for the mid to heavy weight bullets so stubby varmint bullets tend not to have a good bullet land relationship.

Also, you are likely using a powder way too slow and thus not getting consistent burn and alot of fouling.

It is nice to have a baseline to compare to. I bet the rifle shoots as well now as it did then.

270 moa

Machine cut rifling under magifing looks like someone used a axe to it.
Thats why button rifelingis so smooth no maching marks, your rust problem sounds like the metal doen't have enough nikel in it.
Have a 1895 win 303 no rust, 1964 win 70, .225cal no rust.
Usually the barrel will sweat for a few days after shooting, so don't oil it right after cleaning the oil will seal in the moistur. George

Sunday came and went. It was VERY windy here on the farm, and at the range it was only a little more sheltered.

I decided to not over-do the testing today because of the wind.

I did, however, toss about 15 Federal Fusion 150gr rounds down range, against 6 110gr VMAX handloads I had in my pocket for hunting.

I got ~1.75" groups with the Federal and about a 3.5" group with the handloads. I wouldn't call it conclusive on a day like today, but it's a start.

Those 150's have a little more whollop, btw!!

I'll have to try again this week. Stay tuned!! I'll even put my 8.5 to 25 Leupold on it for the actual test :D
 
There was a bit of gusty cross wind here in Sask as well. I tried some hornady hollow points for the first time along with H4831 which I have not used before. I got the hornady hollow points out to the rifling easily, I have used up my box of noslers and wanted to try something a bit different.

Hornady 120 grain hollow points touching the rifling gave me a five shot 1,1'4" group at 100 yds with 71 grns of H1000. It was shooting much better before with this powder with the bullets set back from the rifling.

HDY hollow points with the bullets set back gave me a four shot group of 1,1/4" with 65 grns of H4831. This is the start load in my reference book.

HDY hollow points set back again gave me a four shot 1" group with 64 grns of H4831

Same as above but with 63 grns gave me a four shot group of 3/4". Not bad for a gusty afternoon.

I think it's time to start shooting at long ranges.

Going to the range tomorrow. Hopefully it won't be windy.

I have a big test set up...two bullets, three powders and seating depth tests, plus those factory 130's as a re-benchmark.

Should get SOME kind of useful data out of this. I'll let you all know, of course!!
