.45 Remington 700 MLS wring out session

[mountainam]

I purchased two .45 cal stainless barreled actions from Denny's Sporting Goods the other week and a Donor .50 700 from Hunter. I assembled one this week. It was nice and sunny this afternoon so I decided to try some .35x .45 loads. I am using .35 x.45 MMP long petaled sabots from PR Bullet. I shot Hornady .357 180gr. XTP's I had on hand and was impressed with the grouping. I had a foreign body removed from my shooting eye two days ago so I had to shoot at 50 yards instead of 100 yds. I started out with 100 gr FFG T7 and shot a nice clover leaf. I upped it to 120 grs and the group shrunk a little. I then switched from small rifle to small rifle mag primers and 100 grs. of BH 209. Group stayed about the same at 5/8"c-c. I also tried some 10x but I'll refrain. The sun was bright today so I didn't set up the Choronograph. I hope my vision clears up soon so I can do some shooting from 100 and 200 yds with the .357 XTP's. The 700ML sure shot smooth compared to my .50's and .54. I want to try some 200 gr .358's. If they don't do well I'll try some .40's as soon as my sabots arrive.

Yes.

Tell me about these barreled actions from Denny's. Do they come with the trigger assembly and bolt? Do they have any more? What is their phone #. Thanks.

It's a barreled action. No trigger. It uses the same one that's on a CF. No bolt, no sights, no barrel band, just the assembled action, recoil lug and 26" stainless barrel. It will cost you in the neighborhood of $325. Denny has been putting together complete rifles for the locals and walk-ins. If you can supply a donor .50 cal. (there's a lot of them out there with ruined bores)you can have a complete .45 cal magnum for less than the cost of a Pac-Nor barrel. I'm sure that the Pac-nor's quality exceeds that of the Rem 700ML, but both the ones that I just got greatly exceed the quality of a Savage sad to say. They look mirror smooth. A bore scope may reveal otherwise, but my old eyes can't see ANY flaws. I don't know what cal. you're looking for, but these are .45's and they're going fast. We never checked on .50 or .54's. His phone number is (330)-534-3707. He's closed this morning but if you call and leave a message he'll return your call.

An update on the .45 Rem700ML. I shot the .357 180 XTP's with 140 gr FFFG T7. I set up the chronograph today and these loads clocked out at 2287 fps. and grouped under 5/8". Also yesterday I received my Hornady 200gr .358" RN. They don't have as much flat on them as the 180 XTP's and did not shoot well. They loaded too easily. I then cut a strip of paper from my Leigh ventliner invoice that measured .004" and made some paper patches. They loaded with 25-30lbs force. Man, did that make a difference. A 4 shot group with holes touching. I was using 10x so again, I'll refrain. It makes you feel good like in the old days when you got the patch thickness down on your favorite round ball load.

You beat me to the test. Due to health and help from the weather, I havn't been able to get to the range. Hopefully this week some time. I intend to spend all day with the .45, since I have to travel to the next state for a range, about 50 miles. Can't wait.

I visited an old gunshop yesterday while it was pouring down rain along with tornado warnings. Anyhow, I found some Hornady .41 cal 210 gr XTP's. My .45 Rem 700MLS would not shoot the .40's well so I thought these might work better. I went home and removed my breechplug and pushed the .41's through the bore using MMP tan; Harv blues; and Harv blue crushed ribs all while resting the but on a bathroom scale. I was surprised that the Blue CR's pushed at 37 lbs while the other two pushed at 32 lbs. All of the Tan MMP's that I tried deformed (stretched) the petals. None of the Harvesters deformed. So the MMP's were out of the equation. I shot between rains and the .41's shot 1" high on a clean bore with all subsequent shots punching through the 2nd hole. Winds were erratic so I was shooting at 50 yards so through the same hole at 50 is no big deal. When I get more stabile weather I'll do some 100 and 200yd tests. I swabbed between shots with a dry Butch's patch. Loading pressure increased once the bore was fouled beyond the 37 lbs. so it seemed. I clocked these loads at 2402 fps. I was using 10x so I'll say no more. Compared to my .54 and .50 700ML's , recoil was almost non existent in the .45 700 MLS. This rifle has our .32 ACP conversion using small rifle primers (not Magnums) and there was absolutely no blow-back and no hang-fires to boot. I'm really glad that I stumbled on to these .41 XTP's. We'll have to see how they perform on the buck necks!
