The scope has to go back to the gunsmith tommorrow so I wanted to get alittle something done with the rifle as he was nice enough to let me borrow it.Nice scope by the way.Bell clear and you can dial every oz. of parrallax right out.
If I had to test rifles for a living Ballistic tips are what I would start with.Might not use them for hunting but I've always found that if your rifle will shoot a BT well.You have a "good" gun.
I ran a Redding 7mm STW S bushing die with a .302 diameter bushing for resizing some of the cases I broke the barrel with and I had Randy my gunsmith take a Redding 270 WCF BR seater die and open the sleeve up to fit the 270 STW for bullet seating.Runout on the rounds I reloaded was less than .0035 out on the tip of the bullet.
Dug into my stash and found some 130g Nosler Ballistic tips.And some Rel 25.Ran two loads 80g and 81g of Rel 25 with a CCI 250 mag primer.No pressure sign at all on either load.And the 80g load seemed the best printing at about .76 for 3.The 81g load opened up to about 1.1 cry
Most likley wont spend alot more time with the 130g BT as I want to run mono bullets.Thinking Ill end up with Rel 22 and a lighter bullet.But time will tell.Next trip the Model 33 is going along so I have an idea of how fast im actually pushing.
Now I need to pick up some kind of scope for it to.

I like that camo pattern with the stainless.

Care to explain to the ignorant what "skidding the action forward" means and what it accomplishes?

Dave is a big guy, and what he means is that the barrelled action is moved forward giving a bit more room for his big mitt behind the trigger guard. All you big guys should think about it, that's why we have custom guns built, we are all different sizes and have different tastes.

Just curious if you had an opportunity to run any loads over the chrono yet?

Is campfire camo a standard color pattern you can order from McMillan or did you have that done?

Thanks.

Chrono data is still pending.
CC camo is standard from McM.

Appreciate the info.

I have a 270 Ultra Mag that I still have to stock. After I did it I was sorry I didn't go with the 270 STW.I was trying to find some additional info on the 270 STW and ran across this posting which I thought was rather interesting....

27 cal cats

--------------------------------------------------------------------------------
A few years ago I got a new rem take off sendero bbl. It was 26" varment taper 27 cal for 40.00$
It sat in my shop a while intell I dicided to run the gamet of 27 wild cats. It was fitted to an extra rem action. it war a 6.5-20 leupold scope and a jewald trigger set at 14 oz. I put it in a hs pros. stock.
I shot a few 270 win loads to get an averadge vol. accuracy standed to judge the cats with. 3100fps 130 b-tip .689 group 100 yrds.
First up recamber 270 ackly 3186 fps .563 group 130 b-tip (easy to load and fire form)
270 wacker .015 body taper shoulder moved forward for a 1 cal. neck 3335 fps .675 group 130 b-tip.( a little tougher to make start with 30/06 and fitt fals shoulder fire formed using 18gr win 231 and fill case with pillow fluff)
270 wby 3280 fps .987 group 130 b-tip( made brass out of 7 mag)
270 stw 3525 fps .830 group 130 b-tip( necked down 7 stw brass to fit)
270/338 wacker shortend .1875 to fit 30/06 actions 3615 fps .467 group 130 b-tip moly ( this brass is a little tougher to make move shoulder back trimm aneal size to 30-28 then 270 no fire forming needed)
270 ultra 3598 fps 1.350 group 130 b-tip moly ( necked down 7 ultra to 27 olny one powder would give good vol altho several was tried 91.5gr retumbo)
27 wsm 3385 fps .366 group 130 b-tip( factory brass)
27-7mm wsm 3393 fps .406 group 130 b-tip (necked down 7 wsm brass chamber to 7 wsm laingth)

This cost me abot $350.00 in reloading supplys by the time I worked up to max then shot 10 5 shot groups to get an averadge vol. group for all of them.
the bbl naw sits on my sons ruger short action as a 27-7mm stw. It still shoots good and will bust rock chucks out to about 800 yrds. It is gitting a little throute ware and is gitting quit hard to cleen any more but for 40.00 wat can yo do.

I'm curious to see what kind of velocities you end with in your rifle.
Interesting post GJN thanks for sharing.
