Re: Accurizing a Rem .270 win CDL SF

Gents,
All good points. Thanks for the conversation. I totally agree with you guys. I take all of what you have said into consideration and definitely do my part by eliminating as much human error as possible. Good advice though.

I'm able to get my other hunting rifles down to 1/2 to 3/4 moa all day long with reloads, so the shooting isn't the issue. I ensure the optics are solid and not an issue. I was just checking to see if anyone had some advice that I hadn't tried yet.

For some reason my Rem 700 CDL 270 does not shoot boat tail bullets worth a hoot.It shoots flat based in near one hole groups.Try some Hornady 130gr SP and see how it shoots them.

Something to try thats almost free! Totally strip your barrel bore clean, absolutely no chance of any jacket, powder or carbon ring then let KroilŪ soak in it for about 20 minutes. then spray automotive brake cleaner down the barrel, dry with a patch and immediately oil heavily and patch dry. Choose your bullet and dont switch brands. Some rifles want a heavily fouled barrel and totally refuse to shoot clean. You might find that after doing this your rifles accuracy will improve after about 6 - 8 shots, then after that only clean your barrel when accuracy deteriorates or when it is stored for a lengthy time. - barrels love a proper fouling!

Interesting that your gun doesn't shoot BT's very good but shoots flat base excellent.

I have heard of guns having an ever-so-slightly blemished muzzle crown, such that it disturbs the boat tail bullets just a little bit more than a flat base bullet as it leaves the barrel.

In fact, I had a friend do some testing on a 7mm mag out West because he said that it did about the same as yours, (not good with BT's, but very good with FB bullets). He said that it was due to a very tiny burr at the end of the barrel just inside the bore and out of normal view from the naked eye, unless you knew it was there and looking for it. He said he found it by dragging a stretched out q-tip from just inside the bore and he saw it snag on something. He then took a flashlight and found the culprit. Probably came about from rough cleaning process.

In the end, he had it recrowned and it shoots great with all kinds of bullets, both BT's and FB bullets.

He said that he was told that it is a characteristic of flat base bullets to be less disturbed by small muzzle crown burr's than boat tail bullets. In his particular case, it proved to be true.

I'd like to hear from someone that knows more on this if able. that kind of ballistics info is above my G2.
